LEX PRODUCTS PCS TRIO SINGLE DIMMER/DOUBLE POLE RELAY MODULE (PCS-A-MD-D2R) SPECIFICATION

1. GENERAL 1.1. Dimmer/double pole relay modules shall be responsible for voltage modulation of one (1) 20A 120 VAC AC power circuit and the switching of one (1) 20A 240 VAC AC power circuit. 1.2. Dimmer/double pole relay modules shall be fully compatible with the entirety of the Lex Products PCS TRIO Module Chamber series of power control products. 2. ELECTRICAL 2.1. Dimmer/double pole relay modules shall contain two (2) individually controlled, electrically separate and electronically addressable circuits. 2.2. Dimmer Circuit: 2.2.1. Each dimmer circuit shall be rated to operate at a nominal voltage of 208Y/120 VAC 3-phase, 4-wire plus ground. The nominal frequency shall be 60Hz. 2.2.2. Dimmer circuits shall be capable of operating within a range of 90 to 135 VAC at 50 to 65Hz. 2.2.3. Each circuit's power shall be modulated by using a solid-state relay (SSR) for forward-phasing sine-wave modification. 2.3. Double Pole Relay Circuit: 2.3.1. Each relay circuit shall be rated to operate at a nominal voltage range of 208Y/120 VAC 3-phase, 4-wire plus ground or 240/120 VAC single phase, 2 wire plus ground. The nominal frequency shall be 60Hz. 2.3.2. Relay circuits shall be capable of operating within a range of 90 to 250 VAC at 50 to 65Hz. 2.4. Each circuit shall be protected by a branch-rated, hydraulic-magnetic circuit breaker with a 10,000 AIC surge and 100% trip rating. 2.4.1. The circuit breaker shall be rated for tungsten loads having an inrush rating of no less than 12 times normal current. 2.5. Failure of an individual circuit shall not affect the operation of the remaining circuits. 2.6. Each circuit shall be rated to 20 Amps with the relay circuit rated to 1.5 HP. 3. MECHANICAL 3.1. Each module shall be labeled on its face as 'D2R' indicating Dimmer/Double (2) pole Relay. 3.2. Dimmer/double pole relay modules shall be fully factory wired and ready for installation. 3.3. Module components shall be housed in a removable chassis comprised of 14 gauge powder- coated steel.
