Product Summary

The VI-251-CU is a Battery Charger Current Source Module. The device combines industry standard package with the flexibility of a power converter whose output voltage and output current may be independently set. The float voltage of the VI-251-CU is the point at which the BatMod transitions from constant current to constant voltage. The VI-251-CU is an ideal candidate for battery charging and other applications which require a controlled current source. The device is also available in booster versions that enable the designer to create systems capable of multiple kilowatts of output power. With its wide range of input options, the VI-251-CU is compatible with all major battery types. This new current output module finds application in systems where easily programmable current is of primary importance.
