Milwaukee Resistor Corporation Introduces New Line of Dynamic Breaking Resistors
Milwaukee Resistor Corporation, now in their 62 year of business just introduced a new line of Dynamic Braking Resistors that are used with both AC Variable Frequency Drives and DC Drive applications. This new line of dynamic braking resistors are rated between 300 watts and 6000 watts and are ready for shipment in as little as 24 hours. This new line offers resistors mounted in NEMA type 1 enclosures and are pre-wired for easy installation both at the OEM's factory and at an industrial job-site.
The enclosure is constructed from aluminum and includes two endplates and a screened cover. Milwaukee Resistor Corporation stocks numerous ohmic values of 300 watt and 1500 watt resistors which provides the ability to quickly ship dynamic braking resistors up to 6000 watts. Series/parallel wiring combinations of these stock values are utilized to create numerous other resistance values and braking packages up to 19.2kw are also available.
The Application of Dynamic Braking Resistors..... When a load is being decelerated, the motor acts as a generator, converting the kinetic energy of the load to electrical energy. The dynamic braking circuit converts this electrical energy into another form, heat, through the use of dynamic braking resistors to slow the load. The resistors are sized based on braking torque (ohms) and heat dissipation (watts) as recommended by the manufacturer of the drive and application.
More details can be learned by speaking first-hand with a hands-on application engineer and by visiting the company's website at www.milwaukeeresistor.com.
.........additional company details. Milwaukee Resistor Corp is based in Milwaukee, WI and is celebrating their 62n year in business servicing the industrial and utility marketplaces. The company specializes in the design, marketing and manufacturing of electrical power resistors from milli-watts to megawatts in numerous applications including motion control, crane control, motor stopping and starting, dynamic braking of variable frequency drives, neutral grounding to protect power transformers and generators and loadbanks for testing batteries and generators. Milwaukee Resistor Corp is a member of the Huntington Electric family of companies (www.heiresistors.com).
