Resistive Load Banks

Resistive load banks can be used for testing AC supplies (at unity power factor) or for DC batteries discharge or UPS testing. The load bank size is expressed in kilowatts (kW) or amps (A) at the rated voltage.

Froment’s standard load banks can be used for testing supplies up to a voltage of 690Vac or 500Vdc. The MS range, based on a welded monocoque or modular chassis construction, is primarily for single or three phase testing at up to 2000kW at 690V.


Resistive Elements


The Proofloader uses replaceable load elements which are conservatively rated and sheathed in stainless steel for corrosion resistance. They do not need cooling fins, which means that they are very reliable, because they are not susceptible to hot spots caused by foreign matter or loose fins.


Access and Control


A comprehensive system of guards and interlocks ensures safe and reliable operation, and the Sigma control system provides easy-to-use manual or automatic test programs. Control is either from an intelligent hand terminal, or from a PC running the Sigma PC system software.
