The charging efficiency of the PMDC-30 is up to 96%. PMDC-30 also supports
communication of RS485. PMDC-30 will treat it as conventional engine rather
than Euro 6 engine.
- Alternator type: Conventional alternator
- Alternator input voltage: 12.8V – 12.0V
- Working state: ON – OFF
MULTI-STAGE CHARGING ALGORITHM
PMDC-30 is able to charge House battery through the Intelli-Jay transformer
quickly and fully. Microprocessor-controlled charging algorithm with variable
absorption charging timer to guarantee the optimal charging for batteries of
different discharged states.

GENERAL & SAFETY INFORMATION
This section contains important safety and operation instructions. Please read
and retain this manual for future reference.
The PMDC-30 should be installed by a qualified Auto Electrician with knowledge
of caravan electrical systems. The following recommendations are to be
conducted prior to installation:
- The unit MUST not be disassembled for Safety and Warranty reasons.
- PMDC-30 is designed for internal installation ONLY.
- Recommended cable size for input and output connections to unit is minimum 6mm2. Output charging current of the PMDC-30 charge booster will depend on wire size of the auxiliary circuits in the Charging Vehicle and Caravan.
- Check and verify the input voltage is within the specifications of the unit. (Refer to Specification table)
- Check and confirm the circuit connections to the Alternator or Vehicle battery and Input to the Intelli-Jay transformer polarities are correct.
- Use the shortest possible cable lengths to connect the Input and Output circuits to the unit.
- Ensure there’s sufficient ventilation around the heatsink of the unit

MULTI STAGE CHARGING ALGORITHM
PMDC-30 is able to charge House battery through the Intelli-Jay transformer
quickly and fully. Microprocessor controlled charging algorithm with variable
absorption charging timer to guarantee the optimal charging for batteries of
different discharged states.
Figure 2-2: Charging Algorithm
BATTERY TEMPERATURE COMPENSATION
Battery temperature is a key factor in correct charging, the charging formula
must be adjusted (automatically and in real time) according to the actual
battery temperature to ensure that battery are fully charged but not
overcharged or undercharged. All charging voltages recommended by battery
manufacture are in fact only applied at 20°C – 25°C.
The BTS (Battery Temperature Sensor) terminated to PMDC-30 measures the
temperature of battery and automatically makes adjustments at real time to
properly charge your batteries at the default compensation rate of
-3mv/°C/cell.
If the BTS is not present/connected, the PMDC-30 will use 25°C as default
setting.
