TDK-Lambda has now developed the backflow prevention module (EVS-RP) for EVS series of constant current power supplies with simple function set, suitable for charging electrical energy storage systems. Shipments for this backflow prevention module product called “EVS-RP” are started from November 24, 2015.

■ Main features and benefits: EVS-RP

• Suitable for backflow prevention circuits which prevent the current from electrical energy storage systems when the output power of power supplies is turned off.
• Low loss: Due to using MOS-FET, 72% reduction of forward voltage comparing with schottky-barrier diode.
• Low heat: Less heat as compared to the diode.
• Available to use as the diode when power supplies are parallel operation.

■ Major specifications: EVS-RP
