Industrial DIN Rail UPS

The APC SUA500PDR-S is a 500 VA battery backup designed for industrial panels and DIN rail mounting. It delivers 325 watts of output power at 120 V AC nominal for critical control equipment. The unit includes a hard-wire 3-wire terminal block for permanent installation. It targets automation engineers who need compact uninterruptible power inside a cabinet.

Installation Requirements

Verify that your supply voltage falls within the 75 V to 154 V adjustable mains window or the 82 V to 144 V standard mains window. The output is hard-wired only, so plan for a 3-wire connection with ground. A DB-9 RS-232 serial port provides the management interface; ensure your monitoring system supports this connection. The unit weighs 33.25 lbs and measures 5.80 in high, 14.20 in wide and 6.70 in deep.

Sustained Load Behaviour

At full 325 watt load the battery provides eight minutes of runtime, which is 0.13 hour. Recharge to full capacity takes less than three hours, with a maximum of 2.50 hours specified. This runtime suits orderly shutdown sequences rather than extended operation. The standard battery module is user-replaceable for long-term service.

Questions about this item

What comes in the box and do I need to buy a cable or battery separately?

The package includes the DIN rail UPS with its standard battery installed, a DB-9 RS-232 signalling cable, a software and documentation CD, an installation guide and a wall-mounting template. No extra battery or cable is required for basic operation.

Should I select a different VA or wattage model for my load?

This unit is rated at 500 VA and 325 W; choose it only if your connected equipment draws 325 W or less. There is no higher or lower capacity version of this same model in the listing.

What does the 500 VA rating mean for actual backup time when the UPS is powering my equipment?

At the full 325 W load the battery provides 8 minutes of runtime; lighter loads will extend that time proportionally while the input voltage stays within the 82 V to 144 V mains window.
