Power Transformer GuideTRANSFORMER SELECTION GUIDETransformer Voltage: A transformer's secondary A.C. voltage required varies greatly with the type of rectifier chosen and filter arrangement.Use the formulas below as a guide based on the D.C. voltage you require and the rectifier/filter chosen. All A.C. voltage references are R.M.S. Don'tforget to take into account losses (not included in this guide), especially diode voltage drop. Leave an adequate safety margin for D.C. regulatorvoltage requirements and minimum operating line voltage.Transformer Current Ratings: A transformer's A.C. current rating needs to be recalculated from the D.C. load current. The required currentvaries with type of rectifier chosen and filter type. Use the formulas below as a guide, shown for common D.C. supplies. Included in the formulas ishigher peak to peak capacitor charging current in the filter.Rectifier Selection Notes: When selecting rectifiers remember, average current in a full wave circuit is .5 x I D.C. per diode. In a half wavecircuit, average current is equal to I D.C. per diode. A rating at least twice the output current is recommended to cover turn on surge. In full wavecircuits, the reverse voltage rating should be in excess of 1.4 x V A.C. In half wave circuits, the reverse voltage rating should be in excess of 2.8 x VA.C.Capacitor Selection Notes: When choosing capacitor voltage, allowances should be made for D.C. voltage rise due to transformer regulation.Remember, RMS ripple current in a filter capacitor can be 2 to 3 times D.C. load current. Capacitor life is greatly increased by reducing it'stemperature via less RMS current or reduced ambient temperature.HALF WAVE Resistive LoadFULL WAVE Choke Input LoadPriV A.C.SecV A.C.I D.C.+V D.C.-PriV A.C.SecV A.C.I D.C.++V D.C.-V D.C. = 0.45 X Sec.

Hammond Tube Output Transformers (Overview)Audiophile Tube Output TransformersWhether you are into the clean, free spirited"Single Ended" tube output or high efficiency, high power,"Push-Pull" audio, we have the output transformer for you.We have been producing tube output transformerscontinuously for over half a century, constantly improvingand tweaking their performance. The output transformer isone of the most critical components in a audiophile amplifier.These excellent designs have survived the years andhave enjoyed a recent resurgence along with the tubeindustry.Please note, our specifications are at FULLOUTPUT power. Many "newbies" to the industry usefrequency specification data at milliwatt ranges to inflatetheir claims. Check carefully when comparing manufacturersspecs. We use -1db roll off points to ensure a typicalHAMMOND conservative rating, again at FULL OUTPUTPOWER.To ensure a long life and maximum versatilitythese units are built to and tested at a Hi-Pot rating of2,000 VAC!!!!!Our transformers are of EI laminated design, wedo not offer toroidal designs due to their inability to handletube imbalance and high manufacturing cost.More importantly, our designs are "ear tested".After a new design has passed our extensive testing, it'sgot to sound good too, before we put it on the market!From Bach to rock & three watts to 280 watts, we haveyour output transformer IN STOCK.Single Ended Tube Output TransformersB+ B+Push Pull Tube Output TransformersB+ B+These high quality units are also designed formaximum versatility. All units include an optional use - 40%screen tap (a proven pentode "sweet spot") for "Ultra-Linear" operation. They are designed to be used with mostall power output tubes available today. The ratings shownare at full power and rated plate current. We have alsoadded an epoxy potted series to our line for the ultimate intube output transformers.HAMMOND Interleaved WindingsThe reason for our sparkling high frequencyperformance is the use of interleaved windings betweenthe primary and secondary. The number of interleavedwindings is optimized to the size (wattage) of the unit. Alloutput models (both single ended and push-pull) includemultiple interleaved windings to maximize high frequencyresponse. These windings are machine wound with highquality copper wire The multiple interleaved secondariesare wound (series or parallel connecting them) to match to4, 8 or 16 ohm load impedances.The primaries of each model (including the "singleended"series) include Ultra-Linear taps at the 40% point.Tube Output Transformers - EstheticsThese high quality units are designed for maximumversatility. Designed for both triode or pentodeoperation - Class A operation. All units include an optionaluse - 40% screen tap (a proven pentode "sweet spot") for"Ultra-Linear" operation. The ratings shown are at fullpower and rated plate current.The lamination iron used is a high quality (M6)grade, silicon steel, for low loss and the lowest possibledistortion at bass frequencies. A factory set core capensures against core saturation at full ratings. All singleendedoutput models include multiple interleaved windingsto maximize high frequency response. These windings aremachine wound with high quality copper wire.We have also paid close attention to the "look" ofour units as they are as much on display in some designsas the tubes themselves. Our units are manufactured withhigh grade laminations (M6) and machine wound with highquality copper wire. The core is varnished and oven bakedto ensure quiet operation - even at high ambient temperatures.Then the end bells are bolted on. These end bellsare finished in a tough, low gloss, black powder paint finishto resist scratching. The end bells include knockouts foroptional above chassis wiring.CANADAPhone: (519) 822-2960 Fax: (519) 822-0715USAPhone: (716) 651-0086 Fax: (716) 651-0726 49© 2000www.hammondmfg.com

Line Transformer - Selection GuideSteps To Proper Transformer Selection1) What power is available (you need to know both voltage & frequency).2) Check the operating voltage of your equipment (is it single voltage or multiple?).3) What line frequency will your equipment run on? Either 50, 60 or dual 50/60 Hz.(remember a transformer can not change line frequency).4) Use the chart below to determine your requirements:PowerAvailableYourEquipmentTransformerTypeRequiredVoltageFrequencyVoltageFrequency( (Youmayalsoneedplugadaptors-pg.74)1156010050/60Step Down1155011550None Required - or - Straight Isolation1155011560Will Not work11550115/23050/60None Required - or - Straight Isolation1156011560None Required - or - Straight Isolation1156023050Will Not work1156023060Step Up11560115/23050/60None Required - or - Straight Isolation2305011550Step Down2305011560Will Not work23050115/23050/60None Required - or - Straight Isolation2306011560Step Down2306023050Will Not work2306023060None Required - or - Straight Isolation23060115/23050/60None Required - or - Straight Isolation6) Determine if your equipment is Electronic or Electrical:- Electronic = containing a chips, transistors or a circuit such as a radio, shavers, electric toothbrush, computerprinters, camcorder battery rechargers etc...(if in doubt, check with the manufacturer or refer to yourmanual).- Electrical = Simple heating device, such as irons, hair dryers, electric blankets, curling irons, etc...7) Use the chart below to locate correct series & voltage conversion in the catalog pages that follow:TransformerType(determineddYourEquipmentTypef from chartabove)ElectroniccElectricalS tep UpU se Isolation (series 298)Could use "Auto" (series 170 or 170E)S tep DownU se Isolation (series 172, 179 or 289)Could use "Auto" (series 175)S traight IsolationUseIsolation (series 169 or 171)-IMPORTANT NOTES- "Auto" transformers: are non-isolating units and should be used where only a voltage change is required. The advantagesto using them are light weight (generally half), less expensive and smaller size. The disadvantage is noisolation from the power source. This type of transformer is sometimes referred to as a "converter".- Isolation Transformers: Used for maximum safety, versatility (can be used on both electrical & electronic equipment)and isolation from the power source, used to step-up, step-down or for straight isolation. The disadvantage tousing them is weight (about double the "Auto"), more expensive and larger size. This type of transformer is sometimes referred to as "double-wound"- Adaptors: We strongly recommend that 3-prong "grounded" plugs be used with all of our products. They should beused only with our "grounded" adaptors. Adaptors do not affect voltages, they are a mechanical device only tomatch foreign "pin-outs" of receptacles and/or plugs.CANADAwww.hammondmfg.com© 200068Phone: (519) 822-2960 Fax: (519) 822-0715USAPhone: (716) 651-0086 Fax: (716) 651-0726

Special Designs & Catalog NotesHELPFUL HINTSYour best decision is to try to find a standard, off the shelf transformer to fit your requirements.This ensures a reliable, proven design that seamlessly drops in to your designs. This alsoallows you take advantage of our cost savings by pooling your requirements with thousands of othercustomers who have specified standard transformers. You can also take advantage of our largestock of both field distributor inventories and our own!If you are unable to find what you need from our extensive standard line, remember, wehave over 1 million special designs on file. To help us better serve you, here are a few helpfulhints:1) Make sure simple circuit adjustments can't be made to allow you to use a standard transformer.This will prove much less expensive than a "modified" or "special" design.2) By using the table of contents, try to find the closest possible standard unit (or series) wemake. We have included lots of spec's and photo's to make this easy. Modifying an existingdesign is much easier, less expensive and faster for both of us. (ex.....you must have achassis mount 115V primary, 15V @ 3 Amp secondary.......contact us to quote on a"modified 166M16 except 15V @ 3 Amps").3) Also advise us of any product physical changes you need.4) Please have estimated quantity (production releases) ready and possibly a budget figureto make sure we pick the correct design. If your design appears to be totally custom, contactus for quotes from prints or for initial help. Always feel free to contact our salesoffices or contact our factory direct tech. line @ 519-886-6181.CATALOG NOTESHammond Manufacturing products are continually being revised and improved, to use the bestmaterials available.
