TDK-Lambda EVS Constant Current Switching Power Supplies

TDK-Lambda EVS Constant Current Switching Power Supplies are designed for electrical energy storage and water processing applications. The 300W and 600W power supplies offer a universal 85VAC to 265VAC or 120VDC to 370VDC input with adjustable current settings. The constant current/voltage charging allows a charging method where the charging current/voltage can be controlled in order to protect the battery from overcharging. The EVS devices are ideal for charging various types of storage media, including lithium-ion batteries, nickel hydride batteries, and lead-acid batteries.
