Regulated Power with UPS for Industrial Equipment
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 is available with a 24V 1.2Ah or 24V 4.5Ah DIN mount backup 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, low output ripple, and built-in short-circuit, overload and overvoltage protection. Constant-current limiting automatically reduces output voltage during fault conditions, protecting connected control components from direct shorts and device failures.
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 packs contain sealed batteries that are field replaceable. They include convenient screw terminals for wiring, and an externally 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.
