The S1 Safeguard ignitor turn-off switch increases ballast life by eliminating continuous high-voltage pulses caused by end-of-life, defective, or missing lamps. It eliminates continuous high-voltage pulsing in PSMH or HPS fixtures by automatically disconnecting ignitors after seven minutes of operation, and its design provides 120V and 277V inputs for use with CWA, HX, and reactor-style ballasts. The S1 Safeguard operates with all 39W to 750W PSMH and all 35W to 400W HPS lamps and ballasts with a 90ºC case temperature rating.
