Integral heat pump bypass circuitry allows electronic bypass of speed control. Eliminates overshoots common to on/off and pressure switch controls. Helps prevent evaporator freeze-ups, low pressure cut-outs and liquid-slugged compressors in low ambient conditions. One model covers 120 to 480 VAC. Features hard start (adj. 1 to 5 sec.), low speed cut-off (adj.), high temperature bypass, isolated 24 VAC supply. Controls up to 3 refrigerant circuits. Typical application: heat pumps. 4.5″ × 3″ × 1.75″.

Input: [Control: 18-30 VAC. | Frequency: 50/ 60Hz. 1.8 VA max. | Line input: 120-600VAC.] Output: [Max: 10 amps.| Min: 100 mA.]
