The Studio Solid State Relay Pack is a switching interface for controlling "ON AIR" or "RECORDING" lamps without the necessity of running high AC voltages over long distances by using low voltage DC control. It is designed to interface with the DM Engineering "SLAVE" Studio Relay Pack, but will perform with any DC control input voltage between 5 and 15 VDC. The DC input connector is a Eurostyle pluggable type and input voltage polarity need not be observed. AC input and output connections are standard Nema grounded AC plug and receptacle types. Zero-crossing technology is employed to eliminate noise and UL recognized components are used. The unit is capable of delivering up to 5A @ 125VAC, and is fused at 5A.
