The Luxstat Power Pack by Servodan powers the Luxstat ON/OFF Control Module and the Luxstat Dimming Control Module. It supplies low-voltage power to the control modules via a quick connect cable and has 3 normally open relays (ON/OFF switches controlled by a circuit) to switch line voltage in response to signals from the connected controller. Additionally, the power pack has an automatically resetting fuse. If the current drawn from the power pack exceeds the specifi cations, the +24VDC output and the LED will turn off. When the problem and the primary power are removed, the power pack will restore power.
