Overview
The PS150 is a 12 Vdc power supply that includes a rechargeable 7 Ah valve-regulated lead-acid (VRLA) battery and charging regulator. Charging power for these charging regulators is typically supplied by an unregulated solar panel, AC/AC transformer, or AC/DC converter.
The PS150 are smart chargers that provide 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.

Battery Charging
FLOAT Charging: Vbatt(T) = 13.65−(24 mV) x (T−25) + (0.24 mV) x (T−25)²
Where T is temperature in degrees Celsius ±1% accuracy on charging voltage ove the -40° to +60°C range
Accuracy: ±1% accuracy on charging voltage over -40° to +60°C
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)
Input Voltage Range: 15 to 40 Vdc
Maximum Charging Current: 4.0 Adc typical; 3.2 Adc to 4.9 Adc
depending on individual charger
