SIM240 Changeover Module

The SIM240 static inverter module is designed to eliminate these switching problems. The SIM240 utilises two interposing relays for the two supplies and introduces a time delay of approximately 500m sec between breaking the normal supply andconnecting the static inverter supply. This sequence is reversed upon restoration of the monitored 230 volt supply when the SIM240 immediately breaks the static inverter supply and then after a similar time delay reconnects the normal lighting supply. A dimming isolation facility is incorporated as standard for use with dimming drivers to enable full light output to beachieved in the emergency condition.
