This controller has been superseded by the ASC S5-12V solar charge regulator (LED). This has the same specs with slightly different dimensions (5.1cm x 5.1cm x 3.8cm) It also includes updated features such as 3-stage charging and temperature compensation. You can find an image and also a comparison in the pictures and the installation guide can be found in the related documents. 

This 50W Advanced Solar Panel Charger Controller (also known as a Solar Charge Regulator) uses less than 1/10th the power of the industry average.

The zero battery consumption at night saves lots of power, especially in systems that get covered in snow or need to last through prolonged overcast conditions.

(Almost all other charge regulators have a standby current draw that will drain the battery during poor light conditions).

    * Perfect for telecommunications, solar powered parking meters and other PV systems up to 50W.
    * Save up to 10% of the power from a 5 Watt module.
    * Max Charging current (at 70°C) 4A DC
    * Protection (PV & Battery), against short-circuit & reverse polarity, overload, over temperature & battery removal
    * Can charge a completely discharged battery
    * Extreme design -40 degrees to +70 degrees C
    * Series design (not shunt)
    * Reliable - 100% solid state
    * No radio interference
    * LED indicates charging
    * Wall mountable ABS plastic case
    * Fully encapsulated in epoxy potting
    * Dimensions: 3.8 x 7.0 x 3.1 cm; 50g
    * Battery consumption zero, 0.0 mA
    * Typical solar consumption 5 mA daylight only, 3 mA without LED
   

Ultra low consumption version 5mA (during daylight only).  [Consumption is 3mA if no LED is fitted - please call us for details].

For bulk orders we can customise voltage set-points and wire lead lengths.
