The Simplex Watt-Muncher is a small DC rated load bank used to test battery systems, AC to DC rectifiers and power supplies, battery chargers, UPS systems and DC generators. The Watt-Muncher provides a variable test load used to measure charge and discharge rates, response, stability and endurance. Corresponding calibrations and adjustments can be made while maintaining a constant, precise, resistive load on the power source.
Watt-Munchers can be operated within their rating continuously. The load resistors used in the Watt-Muncher convection cool to less than one-third the maximum, continuous temperature rating of the chromium alloy resistance wire. Fuses on each load step protect the load bank against over-voltage and short circuit.
