Overview

The PS150 is a 12Vdc power supply that includes a rechargeable 8.5 Ah value-regulated lead-acid (VRLA) battery and charging regulator. Charging power for the PS150 is typically supplied by an unregulated solar panel, AC/AC transformer, or AC/DC converter. The PS150 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.

Specifications

Operational Temperature -40° to +60°C (VRLA battery manufacturers state that “heat kills batteries” and recommend operating batteries at ≤ 50°C.)
Dimensions 19.3 x 7.6 x 10.6 cm (7.5 x 3 x 4.2 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 V 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

Additional Compatibility Information

Enclosure Considerations

A desiccated, non-condensing environment is required. The PS150 includes built-in keyhole flanges for mounting to the backplate of a Campbell Scientific enclosure.

Adapters

The PS150 is compatible with the A100 null-modem adapter and the A105 adapter for additional 12 V output terminals. The A100 Null Modem Adapter connects and powers two Campbell Scientific peripherals via two CS I/O 9-pin connectors configured as a null modem. This is useful in linking different communications technologies, such as telephone to radio, at sites that do not have a datalogger. The A105 adapter may be used to provide additional 12 V and ground terminals where the power supply is used to power several devices.

  1. The CH150 or PS150 will pull power only from the source with the highest voltage at that moment. For example, the regulator will take the 20 W input from the 24 Vdc wall transformer rather than from the 18 V 50 W solar panel—even during the day. If the power goes out, the 50 W solar panel will charge during the day with no charging at night.
