Cooper Heavy Duty Occupancy Motion Sensor Switchpack Power Pack Supply HVAC Relay 50/60Hz 120/277V 15 VDC AHSP20-MV

Cooper Arrow Hart AHSP20-MV 120/277VAC occupancy sensor switchpack. Isolated contacts can be used to control HVAC, contactors, motors, etc. Contains a 15 VDC power supply to provide power to Cooper Arrow Hart motion/occupancy sensors and a relay to provide switching to a lighting load. Features include:

• Provides 15 VDC operating voltage to all low voltage, 15 VDC, occupancy sensors and daylighting controllers
• Single switchpack can provide power for up to five sensors
• Up to ten switchpacks can be connected to one sensor for control of multiple circuits
• Capable of switching up to 20 amps
• For use with and rated for magnetic and electronic ballasts, tungsten, and motor loads
• 120 and 277V in the same unit
• Replaces separate transformers and relays
• Reduces installation expense
• Suitable for plenum installations
• Zero-crossing circuit provides increased durability, especially with today's high inrush loads
• Compact size and light weight allows easy mounting through knockout in 4sq. junction box, via 1/2" nipple (from either inside or outside the box) with a simple twist-on nut

Specifications include:

• Power input: 120/277VAC, 50/60Hz
