Table 3 Source priority
| AC MAINS | X | X | |
| SOLAR | X | X | |
| DC IN | X | X | |
| CHARGING PRIORITY | COMBINED | AC MAINS | COMBINED |
Battery Charging of House/Service Battery
The charger automatically starts when the appropriate power is connected, either from grid, generator or solar. With multiple charging stages (Soft-start, bulk, absorption, float & recycle), the PM235C is designed to fully charge the service battery quickly. The PM235C features Microprocessor-controlled charging algorithms. The Float and Recycle charging programs ensure that the battery condition does not change despite being connected for a long period. When the Charger is at Float Stage, if a new input source is added (AC Mains or Solar), the charger will return to the Bulk stage.
- SOFT START
Increases battery life by gently starting to charge the battery 5% of bulk - BULK
Reduces charging time by delivering maximum charge to set voltage life by gently starting to charge the battery 25% of bulk - ABSORPTION
Ensures a full charge to the battery without overcharging - FLOAT
Float charge maintains the battery at 100% charge - RECYCLE
Battery Temperature & Voltage Sensor
The optional battery temperature sensor (P/N: PMBS-3m) can be used with the PM235C to measure the temperature of the battery, allowing the PM235C to to adjust, in real time, the charge to the battery, at a compensation rate of -4mv±10%/ºc/cell. In installations where the BTS is not present, the PM235C will use 25ºC as a default setting. The voltage sensor 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 10% the of the battery capacity (I = 0.1C) by default
Lithium Battery Charging
The PM235C can be configured to charge Lithium batteries. With Lithium batteries, the max charging current will automatically be set at 30% of battery capacity (Imax=0.3C)
Vehicle Battery Charger
Along with a powerful charger for the service battery, PM235C offers a float charge of up to 3A to keep the starter battery topped up, whether connected to AC mains or PV (Solar). When the starter battery is less than 12.4V, the PM235C starts charging after a 30 minute delay, and stops charging when the voltage reaches 12.8V
Power Supply Mode
If no battery is attached to PM235C Unit, it will automatically work as a power supply with a 12.8VDC output.
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.
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.
Categorised Outputs
The 15 outputs are categorised into groups and controls as per below:
| CATEGORY | QTY | DESCRIPTION | POSSIBLE USES |
| Class A5 | 2 | Relay-controlled output with fuse. Protected by the main master switch relay | Water pump |
| Class C2 | 10 | Fused outputs, protected by a master switch relay | Ventilation fan etc |
| Class C3 | 2 | Always On Load (LVD protected) | Fridge, security alarm, etc. |
| Class D | 1 | Constant Supply loads (no discharge protection) | Breakaway systems, Sway Controllers, Radio memory |
Battery Low voltage protection (BLVP or commonly known as an LVD)
PM235C has a built-in low-voltage protection relay. It will disconnect the load once the battery voltage drops below the threshold voltage. The default setting is 10.5VDC. This can be manually turned On/Off via the LOAD button on the LCD display.
NOTE: Class C3 will remain active as long as the battery switch is left on and Class D loads remain active all the time.
Battery switch
The PM235C unit offers a convenient way to switch off the output of the service battery onboard. It protects the service battery from being drained by electronics on board, completely isolating the battery. The PM235C unit also supports a remote manual battery switch. Before using the remote switch, ensure the manual battery switch at the unit is set as “ON”. The switch is only effective when the system has no other energy resource for the load except the battery.
Precise Battery Measurement
PM235C has a battery measurement system controlled by a microprocessor. It measures battery voltage, charge/discharge current, remaining battery capacity (in amp hours) and time remaining. Compared to conventional indicating meters, even small currents can be measured and read accurately with this device. This feature highlights faults, alarms, and installation errors.
NOTE: If you have loads connected directly on the battery instead of the PM235C Power Management System, the measurement will not be accurate. NOTE: P/No. PMSHUNT will be required for heavy loads designed to be connected directly to the battery to ensure SOC% accuracy.
Night Mode
In Night Mode, the backlight of the monitor will turn off and the cooling fans will operate at a decreased speed. Charge current will be reduced to half rated selection when night mode is active.

Operation
Manual switch 
There is an ON/OFF switch on the side of the machine, which is used to control the whole machine to switch on/off when it is powered by battery alone, and to control the whole machine to enter into sleep mode when it is powered by mains power. This switch must be be “ON” in order for the Remote Switch to operate.
Remote switch (optional) 
The remote switch terminals are located next to the positive 14 terminal. This requires the use of an external switch and functions the same way as the manual On/Off Battery Switch on the side of the charger. The Battery switch must be “ON” in order to use the Remote Switch line. When not used both terminals must be bridged together.
Dip switch
There is 5 pin dip switch on the unit which is used for adjusting charging current and battery type. At this time, switch 5 is not used and should be in the “OFF” position
Note: These do not not to be adjusted if a digital screen is used
