Watt-Muncher DC Portable Load Bank Description The Simplex Watt-Muncher is a small DC rated load bank used to test battery systems, AC to DC rectiers 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. The WattMuncher is available in three nominal voltage ranges and three capacity models. In each model, the total load is divided into discrete steps that can be manually applied in any increment of 1A. Watt-Munchers are assembled using the highest quality industrial components including: • chromium alloy load elements rigidly supported by high temperature ceramic clad insulators • heavy duty terminals • industrial toggle switches • fast acting fuses Watt-Munchers are available with three nominal voltages: • high temperature XLP insulated power wiring • 12V DC • precise instruments 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 overvoltage and short circuit. • 24V DC • 32V DC in three models: • Junior (70A) • Standard (100A) • Super (150A) Fully self-contained, lightweight and hand transportable, the Watt-Muncher is the ideal addition to your selection of test instruments.
