Photocontrol - Inverse Ratio Series

Ripley’s microcontroller technology presents a True Inverse Ratio Photocontrol that provides a precise Turn-OFF light level lower than the Turn-ON level

  Zero Cross Switching Technology:
protects the device from inrush
currents, commonly found in LED
SELF-Healing Relay: Our Patent Pending technology
actually works to un-stick the contacts. Allowing
unattended field restoration. 
  3 Tier Power Supply Circuitry: 320
Joule MOV rated, Dual Zener Diode and a 
precision voltage regulator.
  Intelligent Microprocessor: assures
advanced Performance & Reliability
  Tru-Filter®: spectral sensitivity
matches that of the Human Eye

Available Ratios Available Foot Candles Available Cap Colors
0.6:1 1.5 Blue (BL)
0.3:1 2.0 Black (BK)
1:1 3.0 Green (GN)

Examples of turn on /off light levels

  • 0.6:1 Ratio @ 1.5 fc = your lights will turn on at 1.5 fc and off at 0.6 fc. They will turn off earlier or when it is darker in the morning.
  • 1:1 Ratio @3 fc = your lights will turn on  at 3 fc and off at 3 fc. They will turn on and off at the same light level
