Avtron LoadBank Inc. has introduced a new high-capacity, compact portable load bank designed for testing and maintenance applications on generator sets and UPS systems up to 100 kW. The new Minuteman load bank weighs 65 lb., making it light enough to be transported by a single technician. At the same time, it is built to withstand years of service, the Cleveland, Ohio, manufacturer said.
The Minuteman load bank incorporates lightweight aluminized steel construction and fully rated quick-connect load terminals, Avtron said. A 10 ft. cable set and hard-cover protective travel case with casters and telescoping handle is designed to allow for easy transport of multiple units to any job site. In addition, the unit can also be used in parallel, allowing two Minuteman load banks to be used to test systems up to 200 kW.
The load bank is rated for continuous operation at 100 kW at both 240 or 480 VAC, three-phase, 60 Hz and 80 kW at 208 VAC, three-phase, 60 Hz. The Minuteman can also be used for testing single-phase sources, the company said.
The load bank controls and cooling fans are powered by any standard 120 VAC, single-phase wall outlet with detachable line cord provided. An integral control panel is provided for load bank operation and includes the necessary controls, status indicators and a digital metering unit for monitoring volts, amps, kW and frequency with data-logging software included. The data-logging software allows real-time data acquisition of all meter parameters using an infrared USB interface (included) to a customer furnished laptop computer.
