Power Supplies - 48V DC 7.2aH Battery Pack
Battery Pack

The RLH 48V 7.2Ah battery pack is designed to provide reliable UPS backup power for industrial equipment. Ideal for use with RLH UPS systems, battery packs are commonly used with AC/DC power supplies and a UPS battery charge controller to provide uninterrupted backup power in the event of a power outage.

The battery pack is a durable, compression molded fiberglass housing with four 7.2Ah sealed type batteries mounted inside. The battery pack is designed to be wall or panel mounted.

The batteries are field replaceable by qualified personnel, and replacement battery kits are available. The battery pack includes a connection terminal and replaceable protection fuse on the bottom.

RLH battery packs have a long service life up to 5 years of standby service. As with all batteries, excessive discharge cycling, hot or cold temperatures will decrease battery power and life.

Please refer to the ordering information section for replacement batteries.
