PO Box 537 Katy, TX 77492 Phone: (800) 838-4694 Fax: (859)-384-8099 Email: sales@powerohm.com Powerohm Resistors is pleased to offer the third printing of the Powerohm Braking Resistor catalog for Rockwell, Allen Bradley Drives. In addition to the comprehensive Dynamic Braking Resistor selection list, which now includes the New PowerFlex 750 Series of Drives, we have added sections for the Powerohm Resistors new line of stand alone DB Modules/Choppers and the exciting new VBR, a diagnostic tool, which facilitates the proper selection and takes the mystery out of sizing Dynamic Braking Resistors. Contact information to cross reference competitor’s part numbers is listed on page 4. We can quickly provide information on drop in replacements for Post Glover /IPC Resistors. For your convenience we have web access information tools, such as RAISE Proposal Builder and Engineering Assistant. These software program tools provide the user with the opportunity to quickly size and select the correct resistor. This comprehensive guide also offers complete information on all the resistor selections including the panel mounted type PFCR case style resistors, to rugged PF style type screened or louvered enclosed units. All series of Drives, from the PowerFlex 4, 40, 70, 700 and the 750 series are covered, and conveniently listed under the appropriate section by Voltage, HP, Duty Cycle and with minimum and maximum brake torque percent selections, for e-stop, deceleration or overhauling type load applications. Once your part number is selected, additional technical information such as ohms, watts, dimensions, weight, watt seconds and the list price of the unit may be found on pages 40 thru 61 Powerohm’s new DB Module/Chopper is listed on page 28. Models are available in continuous amp ratings of 80, 115, 300, and 600. A crossover chart is available on page 28 which outlines offerings for replacing the Rockwell Series A, (WA, WB and WC models), one to one, that were originally part of the legacy 1336 and 1305 drives. If you desire to employ the combination of a Powerohm Brake Resistor with a stand alone Brake Module/Chopper, those easy to use selection charts of Brake Choppers and corresponding resistor are available on pages 29 and 30. Powerohm’s VBR takes the mystery out of sizing DB resistors. The light compact, portable unit will assist in sizing the proper DB Resistor for any of the PowerFlex Drives series. The unit may be purchased or rented from Powerohm Resistors Inc. A complete description of the unit’s operation is available on pages 31 thru 33, purchasing and rental information is available on page 61. Finally, additional product information such as Installation and Mounting instructions is included as well as other product information pages and useful Application and Engineering Notes.
