Backup Power Supplies for Facility Lights

Backup Power Supplies

Turn your facility lights into emergency lights—no need for generators or separate backup lights. Also known as battery inverters, these power supplies detect outages and shift your lights to battery power. To comply with UL 924 and help you meet NFPA standards, they activate your lights at full brightness for at least 90 minutes, even if they’re off or dimmed. A low-voltage disconnect extends the life of the battery by switching it off before it’s fully drained.

An LED indicator tells you whether your lights are using primary or backup power. The indicator also tells you when these power supplies require maintenance. They have a manual test switch, so you can test them without disrupting the power.

If you have more than one circuit, you’ll need to add a relay to bypass dimmers and on/off controls across circuits. You can also wire these relays to your fire alarm. Pull the alarm to activate lights to full brightness during emergencies, even without an outage. Also known as automatic load control relays.

For the Manufacturer User Manual, click on a part number and select Product Detail.

Note: For many batteries, recycling or other proper disposal is required by law. Do not dispose of batteries in the trash. For recycling drop-off locations visit https://batterynetwork.org/locator/ or call 1-877-2-RECYCLE.

Maximum Recommended Power—Maximum recommended power is the total wattage of connected devices that these power supplies can support.

Cannot Be Sold To—Power supplies that cannot be sold to the listed areas are restricted due to local energy efficiency requirements.

DC Motor Drives

Control the speed and torque of DC motors. These drives have a dial for manual adjustments, or you can automate control by hooking them up to your PLC. Use the potentiometers to set parameters, such as minimum and maximum speed.

Reversing Motor—Operate in either direction with the flip of a switch or an input from your PLC. There’s no need to rewire the drive.
