Larson Electronics’ 120V AC 50/60 Hz explosion-proof uninterruptible power supply is protected by a copper-free, cast aluminum enclosure that is NEMA 3R- and 4-rated. It comes with an output power capacity and maximum configuration power of 500W/750 VA. It contains a leak-proof, maintenance-free, sealed, lead-acid with suspended electrolyte battery. The battery takes roughly three hours to recharge and has a three–to-five-year lifespan.

Para Systems’ Minuteman PRO-RT series uninterruptible power supply (UPS) is designed to provide fail-safe protection from all power anomalies for small to medium-sized security, telephone, server and network peripheral systems. It features load shedding with two controllable receptacle banks, independent battery bypass, plus auto-restart.
