- Page 2 Overview This 12V to 48V / 36V Photonic Universe DC-DC battery charger is fully automatic and ideal for leisure vehicles, commercial and special purpose vehicles, boats, and any other systems with multiple batteries or power sources. The charger operates using an adjustable three-stage charging programme and is suitable for lead acid, AGM, GEL, LiFePO4 and Lithium-ion (NCM) batteries.
- Page 3 Note: the current flowing between the charger and the source battery (12V) will be approximately 3-4 times greater than the current flowing between the charger and the target battery (48V / 36V). The thickness and the current rating of the connecting cables should be chosen accordingly, with the source battery connected by significantly thicker cables.
- Page 4 Green terminals The charger features a pluggable terminal block of 3 green terminals. In a place with limited installation space, the terminal block can be unplugged for connection or disconnection of the wires and then re-inserted. The size of the cable for this terminal block is 0.75mm² and the stripping length is about 6mm.

- Page 7 Reduced current charging The charger will measure the voltage of the source battery at the start and will continue measuring it throughout the charging process. If the voltage of the source battery is low at any point, the charging current will be reduced, until the Recovery voltage value is reached. The exact amount of charging current will depend on the D+ signal setting (DIP switch 2).
- Page 8 LED indicators Note: when the charger starts, it performs a self-test during which all of the LED indicators are on for 1 second. Colour LED status Charger status No D+ signal, no charging Source battery voltage is < 11.5V. Slow flashing If the source battery voltage reduces (1 flash / 5 seconds) further to <...
- Page 9 Float charging stage: after the absorption stage, the charger will reduce the charging voltage to the float voltage and continue charging the target battery with a low current to maintain it at this level. Equalisation: for selected battery types, the charger will perform equalisation charging by timer once a month with a higher charging voltage, in order to bring all battery cells to the same level.
- Page 10 • If the temperature is > 70°C / 68°C but < 72°C / 70°C, the charger tries to limit the input current to reduce the temperature. • If the temperature is > 72°C / 70°C, the charging stops. • If the temperature is > 60°C for 2 minutes, the charging stops. In case if overheating protection stops charging, the charger can Overheating automatically resume charging when the temperature falls below...
