Battery Temperature Sensor

The PMBS (battery sensor cable) is connected to measure the temperature of the battery and automatically adjusts, in real time, to charge the 
battery properly at compensation rate of – 4mv±10%/°C/cell. In case PMBS is not present, the PM235J will use 25°C as default.

Voltage Compensation Charging

With a voltage sensor the PM235J can automatically adjust its output to compensate the voltage drop caused by a cable.  
This assures the right voltage is being delivered for optimal charging.

Adjustable Charging Capacity

Users can adjust the charging current by specifying the battery capacity. The charging current is set at threshold rate of 15% the of 
the battery capacity (I = 0.15C) by default.

Lithium Battery Charging

The PM235J can be configured to charge a lithium battery. With a lithium battery, the max charging current will automatically be set at 

30% of battery capacity (Imax=0.3C).

2.3 Power Supply Mode

If no battery is attached to PM235J unit, it will work as a power supply automatically with a 12.8VDC output.

2.4 PWM Solar Charger Controller

PM235J has a built-in PWM charger for the house battery with:
• Max input voltage 25VDC
•  Max charging current 30A

2.5 Voltage Charging Relay (VCR or commonly known as a VSR)

As a Safety feature, the Slide Out (+L12) and Awning (L13) outputs are disabled when towing vehicle is connected to the Caravan (and 
vehicle battery voltage is detected at >5V). To enable these outputs again, disconnect the vehicle’s power plug from the caravan. If the 
VCR is still engaged, press the PWR button on the LCD or app ON / OFF / ON.
LEAD ACID BATTERY – When the vehicle battery reaches 13.4VDC with threshold time delay, the VCR will charge the house battery from 
the alternator. The VCR will continue the charging until the vehicle battery voltage drops under 12.8VDC.
LiFePO4 LITHIUM BATTERY – When the vehicle battery reaches 13.7VDC with threshold time delay, the VCR will charge the house battery 
from the alternator. The VCR will continue charging until the vehicle battery voltage drops below 13.3VDC with less than 2A charge to the 
house battery with threshold time delay.

NOTE:

 The PM235J, when charging from the vehicle battery, does not provide the 5 stage charge.   

It simply takes whatever power and charging is available from the alternator.

NOTE:

 If your vehicle is fitted with a smart alternator, the VCR charge system (Variable Voltage or Temperature Compensating), the VCR 

charge system may not function correctly and a Projecta IDC25 charging system is recommended.

Please contact Projecta for further information.

ALGORITHM

SOFT START

Increases battery life by gently starting to 
charge the battery at 50% charge rate for 
10 minutes if the battery is less than 11.5V

BULK

Reduces charging time by delivering 
maximum charge to set voltage

ABSORPTION

Ensures a full charge to the battery 
without overcharging

FLOAT

Float charge maintains the battery at 
100% charge

RECYCLE

Restarts the charge every 10 days.
