Overview

Unlit obstruction lights due to power loss imposes significant risks on aircrafts and tall structures. A UPS (Uninterruptible Power Supply) unit is an vital device in obstruction lighting system to backup obstruction lights for continuous operation in the event of power loss.

The UPS unit is compatible for a wide primary AC input from 165VAC to 265VAC. Built-in inverter circuity, battery charger, and high-quality VRLA battery packs for some sub-models or external battery box connected to UPS, provide continuous AC power when primary input AC power is interrupted.

Incorporated surge protector, the UPS is capable of protecting obstruction lighting system from voltage fluctuation and lightning strikes.

REDDOT provides both Standby UPS and Online UPS solutions. UPS capacity is customizable to suit various backup time for obstruction lighting systems.

For obstruction lighting system with high power consumption, or longer backup time required, an extended battery box with high quality SLA UPS battery packs combines with UPS main engine. The combination of UPS engine and extended battery box provide sufficient backup power to obstruction lighting system after blackout.
