TDK-Lambda EVS series constant current power supplies

Click2Contact

The TDK-Lambda EVS series constant current power supplies offer a simple function set, designed for electrical energy storage and water processing applications. The new products will be marketed under the TDK-Lambda brand. In addition to a 300 W board-type fanless model and a 600 W unit model, a dedicated backflow prevention module will also be offered.

In recent years, the demand for electrical energy storage systems for peak shift and peak cut applications as well as for emergency use is rapidly increasing. The EVS series has been designed as a constant current power supply optimal for integration in such systems, providing the required constant current, constant voltage charging capability. The upper output voltage limit as well as the constant current value can be set by the user using equipped trimmers.

The 300 W model realises silent operation through a fanless design. Available output voltage ratings are 18 V (300 W model only), 36 V and 57 V, to suit the requirements of 12 V (300 W model only), 24 V and 48 V storage systems. Parallel operation is also supported, to enable charging of high-capacity storage systems.
