Power supplies for constant current operation
TDK's EVS-RP6020 constant current ac-dc power supplies can accept a 85 to 265 Vac input and have nominal 18V, 36V and 57V outputs for use with 12V, 24V and 48V lithium ion, nickel hydride and lead acid batteries.
TDK's EVS-RP6020 constant current ac-dc power supplies are designed for applications that require constant current operation. They accept a 85 to 265 Vac input and have nominal 18V, 36V and 57V outputs for use with 12V, 24V and 48V lithium ion (Li-Ion), nickel hydride, and lead acid batteries. The float voltage is user adjustable down to the nominal battery voltage. The board style 300W rated models can operate without forced air cooling, with the enclosed 600W models having an internal cooling fan. The units can operate in ambient temperatures ranging from -4 to 158 F with model dependent derating. An external stand-alone reverse protection module prevents backflow of current into the power supply from the battery. Rated at 20A, 7 to 60Vdc, the EVS-RP6020 uses a low resistance Mosfet to reduce the voltage drop to 200mV.
