Watt-Muncher
Portable Load Bank
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. The Watt-Muncher 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.
Resistive Load
Simplex “Powr-Web” iron-chromium-aluminum alloy power
resistors operating at 312°C, rated for maximum continuous
1038°C; continuously supported by high temperature ceramic
clad insulators
Watt-Munchers are assembled using the highest quality industrial components including:
chromium alloy load elements rigidlysupported by high temperature ceramicclad insulators,heavy duty terminals,industrial toggle switches,fast acting fuses,high temperature XLP insulated powerwiring,and 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.
Fully self-contained, lightweight and hand transportable, the Watt-Muncher is the ideal addition to your selection of test instruments.
