Power Supplies

Cooper Notification of Long Branch, New Jersey, has added two new power supplies to its Wheelock line. The PS-6 (6-amp power supply) and PS-8 (8-amp power supply) are used to extend notification circuits. Both models are equipped to operate on either 110 VDC or 220 VDC power and are available with a red or black enclosure. The new features include the distinguishable ground fault LED, true input to output mapping, a power supply expansion board, and a larger chassis on the PS-8. The units can be used in a split mode operation, allowing the independent operation of the two inputs to any of the outputs. The larger chassis on the PS-8 provides additional cabinet room enabling mounting of addressable control modules inside the cabinet instead of mounting an external box and conduit between the cabinet and the power supply.
