OrderableGSA12 V Charging Regulator
Best for general applications
Overview
The CH150 is a charging regulator for an external rechargeable 12 V VRLA (valve-regulated lead-acid) battery, such as the BP12 or BP24 offered by Campbell Scientific. Charging power for the CH150 is typically supplied by an unregulated solar panel, AC/AC transformer, or AC/DC converter. The CH150 provides charging with temperature compensation for optimal charging and battery life. A maximum power point tracking algorithm is incorporated for solar inputs to maximize available solar charging resources.
The CH150 is ETL certified. The ETL Mark is proof of product compliance to North American safety standards.
Key Advantages
Technical Description
The CH150 is a micro-controller-based smart charger with temperature compensation that optimizes battery charging and increases the battery's life. Two input terminals enable simultaneous connection of two charging sources. They also incorporate a maximum power point tracking algorithm for solar inputs that maximizes available solar charging resources.
The CH150 has several safety features intended to protect the charging source, battery, charger, and load devices. Battery-reversal protection is included, as well as ESD and surge protection on all of the CH150 inputs and outputs.
The CH150 replaced the CH100.
Benefits
- Protects against high-amperage and high-voltage damage to power supply
- Battery reversal protection
- Allows simultaneous connection of two charging sources (e.g., solar panel, ac wall charger)
- ETL listed Class 2 power supply
Specifications
- Operational Temperature
- -40° to +60°C
(VRLA battery manufacturers state that “heat kills batteries” and recommend operating batteries at ≤ 50°C.)
- Dimensions
- 7.5 x 3.7 x 10.0 cm
(3 x 1.5 x 3.9 in.)
CHARGE - CHARGE Terminals (AC or DC Source)
- AC
- 18 to 24 VRMS
(internally limited to 1.2 ARMS)
- DC
- 16 to 40 Vdc
(internally limited to 0.85 Adc)
SOLAR Terminals (Solar Panel or Other DC Source)
- -NOTE-
- Battery voltages below 8.7 V may result in < 3.0 A current limit because of fold-back current limit.
- Input Voltage Range
- 15 to 40 Vdc
- Maximum Charging Current
- 4.0 Adc typical
(3.2 to 4.9 Adc depending upon individual charger)
Quiescent Current
- No Charge Source Present
- 160 μA at 13.7 Vdc
- No Battery Connected
- 930 μA at 30 volt input voltage (ac or dc)
Battery Charging
- -NOTE-
- The "T" represents temperature in degrees Celsius.
- FLOAT Charging
- Vbatt(T) = 13.65 V - (24 mV) x (T - 25) + (0.24 mV) x (T - 25)2
- Accuracy
- ±1%
(on charging voltage over -40° to +60°C)
Power Out (+12 Terminals)
- Voltage
- Unregulated 12 V from battery
(4.65 A solid-state circuit breaker)
- Standards
- ETL Listed Class 2 power supply
