The Uninterruptible Power Supply (UPS) is maintenance free and requires no battery. The UPS is 100W and is 24 V DC. The ultracapacitor technology reduces the risk of downtime from battery failures and saves expenses on battery inspections and replacement. The UPS eliminates cost on HazMat waste battery disposal and hydrogen gas buildup inside the enclosure. The Panduit Industrial Network UPS is intended to provide uninterrupted power for critical applications including managed network switches, micro PLCs, and HMIs deployed on the factory floor. The device is suitable for use in extremely low temperature environments and elevated temperatures without loss of performance or reduced life.
