3 Amp Charge Controller

Application

This charge controller is used to charge a battery from a PV power source. This charge controller can be ordered with a special float voltage to charge small batteries used for Video or digital cameras or small security camera systems. The exceptional small size of this unit makes it extremely portable and able to fit almost anywhere in the user equipment.

Features

  • Single unit 12/24 V operation

  • Able to charge 12 V battery from 24 V PV

  • Special order units can charge lower voltage rechargeable battery
      • For example, a 7.2 V li-ion battery from a 12 V nominal solar panel with complete energy transfer

  • Will also charge batteries from rectified AC through an energy limited transformer, great for systems with optional AC charging or UPS systems

  • Real world 15 - 30 % more current than conventional technology into discharged batteries

  • Overvoltage Protection
      • Regulates output at float level even without batteries connected (or bad batteries)

** Special units have a suffix of B XX after the part number. The float value of the charge controller is XX. For example PT 12/24 - 3 B8.4 will charge a li-ion battery to 8.4 V from a nominal 12 V solar panel. Note that the charge current increase by the ratio of approx. 15/8.4. Thus a 1 amp 12 V nominal solar panel will charge the li-ion battery at approx. 1.78 amps.
