Die PS150 ist eine 12V Stromversorgung bestehend einer 7Ah-Bleigelbatterie (VRLA) und einem Laderegler. Ladestrom wird normalerweise durch Solarzellen oder Netzteile geliefert.
Die PS150 einthält einen intelligenten Laderegler mit Temperaturkompensation, die optimale Ladung und ein langes Leben der Batterie ermöglichen. Ein Algorithmus ermittelt den Punkt der maximalen Leistung einer Solarzelle zur optimalen Ausnutzung einer Solarstromquelle.
CE Compliant
Operational Temperature Range*: −40° to +60°C

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
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)
Power Out (+12 terminals)
Voltage: Unregulated 12 V from battery
4.65 A solid state circuit breaker
ETL Listed Class 2 power supply
