Description
Doug Fleenor Design makes a series of Relay Packs that are controlled by DMX512. This single channel unit is designed to switch up to a 20 amp line voltage load. It is built with a 30 amp relay for robust performance. The unit is provided with two 18″ 12/3 SJ pigtails for line in and switched line out. Supplied with 15 amp parallel blade connectors as standard, the unit may be wired with higher rating connectors by special order or may be rewired by the customer.
Doug Fleenor Design Relay Packs use dry contact air-gap relays. These relays have advantages and disadvantages over the solid state relays found in dimmer packs. Solid state relays can be switched on and off rapidly with no wear, but tend to leak current even when in the off position. Air-gap relays do not leak current, but due to their mechanical design have a finite life span. Doug Fleenor Design Relay Packs should be used where a true off condition is required (no voltage, no current). They should not be used in applications where they will be turned on and off rapidly (for example in chase lights). Ideal applications include fog machines, power to moving light fixtures, motorized disco effects, strobe lights, fans, etc.
