The Watt-Muncher by Simplex is a Portable DC load bank which is designed to test the battery systems. It can also be used in AC to DC rectifier, power supplies, battery chargers, UPS systems and DC generators. This is the ideal tool that can give variable test loading which is used to measure charge and discharge rates, response, stability and endurance. For this specific model, it features its capacity to enhance the performance of a system in terms of constant, precision and resistive load on the power source. Plus, it comes with a step protect the load bank for preventing over voltage and short circuit.
