Dwyer DPC-ACS is a duplexing pump controller designed for controlling the operation of two pumps. It can operate in temperatures ranging from -4 to 131°F (-20 to 55°C) and can be stored in temperatures ranging from -40 to 185°F (-40 to 85°C). It requires a power supply of 120 VAC/DC, 240 VAC, or 24 VAC/DC. The controller features an 8-pin octal mounting and consumes approximately 3 VA of power. It is housed in a polycarbonate dust cover enclosure. The electrical rating of the controller allows for 10 A @ 240 VAC resistive, 1/8 hp @ 120 VAC, 1/4 hp @ 240 VAC inductive, and 360 VA @ 240 VAC inductive. The switch type is SPDT and the controller has two LED indicators to show the active output relay.
