PS150/CH150 12 V Charging Regulators
3.6 LED Indicator
The green “Charge” LED will flash approximately once a second if all
incoming connections are correct and there is an adequate charging voltage
present.
4. Specifications

Physical Specifications
PS150: 10.6 cm (4.2 in) tall, 19.3 cm (7.5 in)
long, 7.6 cm (3 in) wide
CH150: 10.0 cm (3.9 in) tall, 7.5 cm (3 in) long,
3.7 cm (1.5 in) wide
1. Battery voltages below 8.7 V may result in < 3.0 A current limit because of
foldback current limit.
2. VRLA battery manufacturers state that “heat kills batteries” and recommend
operating batteries ≤ 50°C.
