300-600W Constant Current Power Supplies are Suitable for Charging Energy Storage Systems
2016-07-12 | ReturnThe EVS series will accept a wide 85 to 265Vac input and has 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. Parallel operation is possible.
The units can operate in ambient temperatures ranging from -20 to 70oC with model dependent derating. The 300W supplies measure 3.31” x 1.65” x 7.09” and have an optional perforated cover, with the 600W measuring 4.72” x 2.4” x 7.48”. A remote on/off function can also be selected on both power levels.
An external stand-alone reverse protection module is also available, preventing 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 less than 200mV. This module is available as a board assembly or with a mounting bracket, measuring 1.97” x 1.02” x 3.05” and 2.36” x 1.26” x 3.68” respectively.
The power supplies have 3kVac input to output, 2kVac input to ground and 500Vdc output to ground isolation. All are certified to UL/CSA/IEC/EN 60950-1 and carry the CE mark for the Low Voltage and RoHS2 Directives. The EVS complies with EN55011/EN55022-B conducted emissions and the IEC 61000-3-2 harmonics and IEC 61000-4 immunity standards.
More information can be obtained at the following TDK-Lambda Americas website, http://www.us.tdk-lambda.com/lp/products/evs-series.htm, or by calling 800-LAMBDA-4. Product availability for the EVS series can be found via the link to TDK-Lambda’s distributor network (see “Check Distributor Stock”) at http://www.us.tdk-lambda.com/lp/
