Constant current power supplies charge energy storage systems

TDK-LAMBDA EVS constant current ac-dc board style 300W rated power supplies can operate without forced air cooling, with the enclosed 600W models having an internal cooling fan. Units come with five-year warranty and are ideal for charging batteries in energy storage systems, or for other applications requiring constant current outputs. Products will accept a wide 85 to 265Vac input and have nominal 18V (300W only), 36V and 57V outputs for use with 12V, 24V and 48V lithium ion, nickel hydride and lead acid batteries. The float voltage is user adjustable down to the nominal battery voltage and the charging current can set from 50% to 100% of the rated current. http://www.us.tdk-lambda.com/lp
