2.5 PWM Solar Charger Controller
PM235C has a built-in PWM charger for the service battery with:
• Max input voltage 30VDC
• Max charging current 30A
• Max supply current 30A
* PM235C may cause LiFePO4 BMS over-voltage protecting to trigger when charging through Solar. In this case, disconnect the solar
charge fuse and discharge the battery.
2.6 Voltage charging relay (commonly known as VSR)
PM235C has a built-in voltage charging relay (also known as a VSR), which offers a convenient source to charge the service battery via the
alternator whilst the engine is running or via an external DC-DC charger.
LEAD ACID BATTERY – When the starter battery reaches 13.4VDC with threshold time delay, the VSR will charge the service battery from
the alternator. The VSR will continue the charging until the starter battery voltage drops under 12.8VDC.
LiFePO4 LITHIUM BATTERY – When the starter battery reaches 14.0VDC with threshold time delay, the VSR will charge the service battery
from the alternator. The VSR will continue charging until the starter battery charging current is less than 2A charge to the service battery
with threshold time delay.
NOTE: The PM235C starter battery input does not provide 5-stage charging.
It takes whatever power is available from the alternator to charge.
NOTE: If your vehicle is fitted with a smart charging system (Variable Voltage or Temperature Compensating), the VSR charge system may
not function correctly and the Projecta PMDCS range of DC-DC chargers are recommended.
Please consult your local dealer or installer for further information.
