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: •...
2.2 BLOCK DIAGRAM Figure 2-1: Block Diagram of PMDC-30 Alternator Motor DC/DC Intelli-Jay Transformer battery Converter Temperature detect Voltage detect Voltage detect Switch 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.
2.4 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.
