Energy Saving Module

Innovative & cost-cutting

Energy-Saving Module (ESM)

for DC-brakes

ESM energy-saving module for electromagnetic devices

The energy-saving module optimizes the control of inductive loads such as brakes, solenoids and valves.
The electronic module uses pulse-width modulation to keep the voltage supplied to the electromagnetic device at a constant level over a wide input voltage and temperature range.
The full operating voltage is applied for a limited period of time to ensure fast and powerful switching when the load is switched on. The electronic module then reduces the power supply to constant holding voltage. A 30% reduction provides power savings of 50%.
Moreover, lower intrinsic heating of the load extends the operating temperature range.
The module is very compact thanks to the use of state-of-the-art microelectronics and power electronics components. Overexcitation time and holding voltage can be factory-programmed to customer requirements.
