Abstract

Specifies requirements for constant-potential type battery chargers designed to float-charge stationary batteries and which may simultaneously supply power to a direct current load. Covers both performance and safety requirements and provides test methods.

Scope

This Standard specifies requirements for stabilized constant-potential battery chargers that are designed to supply direct current power from an alternating current source, while charging a float-type stationary battery, and which may simultaneously supply power to a connected direct current system load.

NOTE: Appendix A provides guidance on information to be supplied by a purchaser.
