Product Information

Product Information

150VA-1500VA 230V AC Single Phase Output Static Inverter System suitable for operation with standard mains luminaires. Available with 1 or 3hr battery configuration, load / battery monitoring as well as integral 4 way fused distribution. The EF5 ELI range of emergency lighting inverters performs automatic load tests of the luminaires by monitoring the current they draw.

There is no need for additional control wiring; they are suitable for loads between 150VA & 1500VA and where luminaires are directly connected to the system output. 4 fused load paths with earth leakage detection can be monitored giving the user defined areas in which to easily locate faults, load flexibility allows any one load line to be maintained, non-maintained or switched. The systems are designed with space saving as a priority.
