Emergency Lighting Inverters Description With the advent of new NFPA and life safety codes, the use of Emergency Lighting Inverters has now become common place. In order to supply the demand, Controlled Power Company has developed an entire line of no-break, power conditioning, NFPA and life safety code compliant, emergency lighting inverters. All of Controlled Power Company's emergency lighting inverters are listed to UL924/UL924a standards and are also NFPA 101 compliant.

An Emergency Lighting Inverter is often referred to as a "UPS (Uninterruptible Power System) for emergency lighting". This description is accurate for each of our emergency lighting inverter products, in that they are a true uninterruptible, no-break power supply.

When selecting an emergency lighting inverter (UPS for emergency lighting), it is mandatory that the system is UL924 listed. UL924 ensures that the battery backup system has passed several critical discharge and recharge tests which are required for life safety. UL924 Listed Emergency Lighting Inverters.

NiCad batteries are useful in applications requiring very high discharge rates because they can withstand such scenarios with little damage or loss of capacity. Nickel–Cadmium batteries are made in a wide range of sizes and capacities, from portable sealed types comparable to carbon-zinc dry cells, to large ventilated cells used for standby and motive power.

 

Compared to other rechargeable cells, NiCd batteries offer good cycle life and performance at low temperatures with fair capacity low internal resistance. Their true advantage is the ability to deliver practically full capacity at high discharge rates. However, their materials are more costly than lead acid batteries, and the cells have high self-discharge rates.
