DIN rail UPS battery backup offers network-grade power protection for industrial and machine control installations.

  • Recommended for industrial locations where temperatures range within 0°C and 50°C
  • Protects equipment against blackouts, brownouts, overvoltages, surges and line noise
  • Keeps power running during brief outages to allow time for safe system shutdown
  • Restarts automatically when power is restored, eliminating a costly site visit
  • Built-in clamp mounts easily to a “top hat” 35mm DIN rail with no mounting screws or brackets required
  • 2-year limited warranty


Flexible Power Protection for Smart Industrial Applications
The DIN500AC standby UPS system with hardwire AC input/output delivers reliable power and battery backup for computing, networking, control and storage equipment in factories, warehouses, edge computing locations and automated manufacturing and fabrication facilities. The rugged compact housing withstands demanding conditions and integrates seamlessly and securely into electrical enclosures in any non-traditional IT environment.

Ideal for Factory Floors and Extreme Temperatures
Get full use of the DIN500AC’s power capacity because there is no derating based on its operating temperature range of 0°C (32°F) to 50°C (122˚F), which expands the number of locations in which it can be used. Built to fit into small spaces, the DIN500AC is a UL 508 recognized component for use in industrial panels. Its pre-installed clamp enables quick mounting to a 35 mm DIN rail. Its fanless design reduces noise and increases reliability.

Reliable Battery Backup Keeps You Operational Through Power Outages
Power outages not only drain productivity from the factory floor, but they also damage expensive equipment. The DIN500AC protects productivity by providing enough runtime to maintain operation during a brief power outage and protects equipment by allowing it to complete an operation during an extended outage. It also prevents brownouts, overvoltages, surges and line noise from damaging equipment that could destroy data and contribute to costly downtime.

Convenient Automatic Restart
The DIN500AC automatically restarts when AC power is restored after an outage, eliminating the need for a costly site visit.

Stay in Control of Your Operation
LEDs on the front panel confirm normal operation and indicate alarm or fault status. Remote on/off and a battery indicator mode can help you avoid maintenance surprises. The DIN500AC is compatible with PowerAlert® Office software for UPS monitoring and control via USB connection.

Easy Preventative Maintenance and Initial Troubleshooting
The DIN500AC’s self-test capability and user-replaceable internal battery can extend the life of the UPS and minimize disruption to operations. A resettable circuit breaker helps prevent dangerous system overloads.
