S Series electronic photocontrols have a spectral response that mirrors that of the human eye. Tight On /Off ratios and a cadmium sulfide sensor with minimal sensitivity to invisible light (ultra-violet & infra-red) provide energy savings from minimal burning hours. S Series units have extended life due to non-chatter operation at load break and having the cadmium sulfide sensor operate in a low voltage DC electronic circuit.

• Meets or exceeds ANSI C136.10.
• Proven DC circuit design.
• Close 1:1.5 on to off operating ratio.
• Non-chatter load break.
• Light level sensing with a spectral response similar to visible light (not sensitive to UV & IR).
• Heavy duty construction.

• 12 year expected life.
• Low power consumption and extended life from "cool" operating DC circuit.
• Close ratio reduces burning hours at sunrise.
• Reduced burning with minimal affect of UV & IR.
• Significantly reduced energy costs.
• Significantly reduced maintenance costs.
