Resistive Load Bank
25-75kW, 120-480VAC, 1 or 3phase

This LIBERTY model air cooled load bank is rated for continuous operation, is ultra-compact, portable, easy to transport and has digital metering and data logging software included. Travel case also included.

The Liberty Load Bank is specifically designed for testing and routine maintenance of smaller generators and UPS systems.  At only 69 pounds, it is light enough to be easily moved and transported by one technician, and rugged enough to stand up to years of reliable service.  The Liberty Load Bank features light-weight aluminum and aluminized steel construction, and quick-connect load terminals.  It comes standard with a hard-cover protective travel case on casters with a telescoping handle.

The load bank is available in four versions:

    75kW at 240Vac single phase

The load bank controls and cooling fans are powered by any standard 120Vac single phase wall outlet with the detachable line cord that is provided.  An integral control panel is provided for load bank operation and includes the necessary controls and status indicators.  Digital metering is provided by the Advanced Digital Monitoring System (ADMS).  The ADMS meter provides faceplate display of Volts, Amps, Frequency and kW.  The communicator EXT Data Logging Software allows real time data acquisition and trending of all meter parameters from your laptop PC or PDA.  An infrared/USB interface cable is included for "Plug and Play" convenience.

     - compact and simple operation
     - light-weight aluminum construction
