Model APD solid-state current sensing switch monitors on-off status of blower motors to provide fan proving for S2000/S2020 steam humidifiers; operates a spring-type damper for fresh air; and monitors the on-off status of various electrical loads, direct-drive units, and exhaust fans. The split core feature eliminates the need to splice wires. It has an amperage range of 0.75-200 A, and an output range of 1 A at 30 V ac/dc. Features include a low 0.15-A turn-on and a mounting bracket.

EWC Controls, 385 Hwy 33, Englishtown, NJ 07726; 800-446-3110; 732-446-5362 (fax); www.ewccontrols.com
