All Charge Controllers
  • Combines three functions in one: charge controller +flexible timer + LED drivers
  • Developed especially for rough environments, solar LED lamps, and solar LED street lights
  • Fully protected by the encapsulated case (protection class IP68): increased lifetime and reliability, reduced costs
  • Flexible dimming functions: renders ambient, pleasant light and extends operation time
  • Auto-protect function: two voltage disconnects extends system operation time and reliability
  • Small size – fits everywhere
  • True colour PWM dimming
  • Charge controllers are the core of every PV system, precisely controlling the energy flow, protecting the battery, and increasing system efficiency. Harsh weather conditions may damage the electronics. In order to protect these core elements, increase system operation time, reliability, and efficiency, Phocos has designed a product line with fully encapsulated housing (protection class IP68): the CIS series.
  • • The built-in LED driver, timer and charge controller are harmonically combined and protected in one fully encapsulated housing (IP68), increasing system reliability, lifetime and lowering investment costs.
  • • An on/off timer combined with an adjustable dimming function renders flexibility extending operation time and furthermore, saves energy.
  • • The CIS-LED also offers an auto-protect function: by means of its two low voltage disconnect levels, the LEDs light will automatically be dimmed when the charge of the battery is getting low. The levels can be programmed by means of remote control CIS-CU.
