High frequency tools and generatorsHigh frequency tools and generatorsContinued next pageHigh frequency grinding toolsA frequency converter is necessary for the operation of BOSCH HR tools.All HF electro tools are in principle delivered without plug since determination of the rotary field is necessary before connection.Operating frequency: the use of a 3-phase supply with increased frequency of 200 or 300 Hz permits the combination of high electrical power output and lowmotor weight. Thanks to the motor with no wearing parts and service-friendly design, our high frequency electric tools are well known to have a long lifetimeeven under conditions of heavy demand (e. g. in foundries) at low maintenance costs.The rotary speed drop is only about 5 % at rated load. This ensures that the recommended cutting speeds can be fully utilised when grinding and drilling.The present range of HF tools consists of angle grinders and straight grinders:Continued next pageHigh frequency grinding toolsThe two single-workplace converters HFS 17-300 und HFS 27-300 from FEIN now make industrial high-frequencygrinding straightforward, economical and mobile for everyone. Individual high-frequency grinderscan now be used for continuous operation where stationary high-frequency solutions are not cost-effective.It is especially at building sites, also in smaller foundries as well as in shipbuilding, steel construction andcompanies fabricating vessels and tanks where you can benefit from the new FEIN single-workplaceconverters with the advantages of high-frequency technology for all kinds of industrial grinding.Continued next pageElectrical generatorswith synchronous generator/inverterType of protection IP 23 – applied in accordance with DIN VDE 0100-704 also for use on buildingsites.Application: the electrical generators in synchronous design deliver electricity in a variety of applicationareas. They are especially suitable as mobile sources of energy in the commercial and industrial sector.Synchronous generators are suitable for loads with high starting current , such as angle grinders, drills andpumps, as well as for ohmic loads (household appliances).Execution: all electrical generators are fitted with engines of well known brands. Die OHV petrol engines(with valves on the upper side) of the GX series distinguish themselves due to their silent operation andfavourable consumption. With automatic engine shut-off when oil quantity is less, a thermal circuit breaker.INVERTER: is a generator technology on high level. The power quality ensures operation of highly sensitivedevices, such as computers, electrical controls, high-frequency tools. INVERTERS stand out for theircompact design, the low noise level, consumption and weight. is a generator technology on high level.The power quality ensures operation of highly sensitive devices, such as computers, electrical controls,high-frequency tools. INVERTERS stand out for their compact design, the low noise level, consumption andweight.Ohmic load:They consists of one or more resistances, i.e. electric components,which produces heat when voltage is applied.Examples: oven, bulb, iron, toaster, hair dryer.Inductive load:They contain electric components, which produce electromagnetism.Voltage and current (both sinusoidal) are out of phase, i.e. they reach theirpeaks at different times and require a current 2 to 3 times the currentduring continuous operation as starting current for a short duration.Examples: Fans, drilling machines, pumps, compressors, concrete mixers.h Prices on request.t Technical Hotline +49(0)711 9813-360Electric Tools2010/111247
