Regulated Power with UPS for Industrial Equipment

Power Supplies - Integrated 75W AC/DC UPS with Battery Backup
UPS with Battery Backup

The RLH 75W AC/DC 24V power supply with integrated battery charger offers a complete power system designed for 24VDC UPS applications. The compact switching power supply has a built-in UPS charge controller, and optional DIN mount 24V 1.2AH battery pack. This system is designed to provide regulated 24V power for industrial equipment, while providing battery backup power in the event of a source power interruption.

The system features flexible AC or DC input, with low output ripple along with short circuit, overvoltage and overload protection.

The integrated charge controller continuously maintains the correct charge level on the battery and ensures a seamless power transition to battery power when needed for a complete UPS power supply solution.

The optional battery pack contains sealed batteries that are field replaceable. The battery pack has a convenient screw terminal for wiring, and an external replaceable fuse for protection.

This compact UPS system offers an excellent price/performance ratio, and provides tightly regulated output voltage for sensitive loads in industrial environments. The constant-current, short-circuit protection limits the output current as the voltage is reduced, to safely protect the control components from direct shorts and device failures.
