Product Description

AC LOAD BANKS

Purely resistive load bank is the most common type of load bank, and it proves equivalent loading of both generator and prime mover. That is, for each kilowatt of load applied to the generator by the load bank, an equal amount of electrical energy converts to heat by power resistors, in a general way, this heat must be dissipated from the load bank by air forced means or other convection.

The JMHing’s resistors are made by high quality finned tubular heating elements, they are of the type where the surface area is enlarged by a strip in order to heat gases. At high power the surface temperature is small and the heating element is short. Meanwhile, Load elements are cooled usually via Fan Forced Air, blower power is typically provided by an outside source. Selected load banks are available with blower power derived from the power source under test.

JMHing’s AC resistive load banks can be further divided into these categories:

AC Small Portable: A resistive load bank easily carried or pushed on strong robust swivel wheels for testing and maintaining AC power equipment such as UPS systems and generators up to 150 kW.
AC Large Portable: A resistive load bank on strong robust swivel wheels for testing and maintaining larger AC power equipment such as UPS systems and generators up to 1000 kW.
AC Stationary: A resistive load bank for testing and maintaining AC power equipment such as UPS systems and generators at one location up to 4600 kW. Many models can be used as modular building blocks for applications requiring capacity of tens or hundreds of megawatts. Also the load banks can be loaded on a trailer for more flexibility.
AC Medium/High Voltage: A resistive load bank for testing and maintaining larger generators and other AC power equipment up to 7000 kW and up to 15,000 volts.
