This controller has been superseded by the ASC S3-12V solar charge regulator (LED). This has the same specs and dimensions but includes updated features such as 3-stage charging and temperature compensation. The third picture shows the front label and the installation guide can be found in the related documents. 

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 small PV systems up to 30W.
• Save up to 10% of the power from a 5 Watt module.
• Protection (PV & Battery), against short-circuit & reverse polarity, overload, over temperature & battery removal
• Can charge a completely discharged battery
• Extreme design -40 degrees to +50 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: 5.1 x 7.0 x 3.8 cm; 50g
• Battery consumption zero, 0.0 mA
• Typical solar consumption 7 mA daylight only with LED, 3 mA without LED

Ultra low consumption version (1mA during daylight only) with no LED available - please call us for details.
For bulk orders we can customise voltage set-points and wire lead lengths.
