INSTRUCTION MANUAL
Overview
This 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 12V 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. The product features high frequency switching and buck-boost power conversion technology for reliable, consistent performance.
The D+ terminal of the charger activates the charging function automatically when the vehicle alternator starts, avoiding battery discharge when it stops. A range of protection functions enables the charger to automatically disconnect the target (OUT) battery from the source (IN) battery under extreme conditions, such as in case of overheating, overvoltage, short circuits, and over-currents.
The charger includes ports for a remote meter or a Bluetooth dongle (both sold separately), allowing data to be viewed on an LCD display or through a mobile phone app when connected.
An optional external temperature sensor (sold separately) can be connected to the charger for automatic adjustment of the charging voltages depending on the ambient temperature (leadacid batteries only), keeping the charging programme to optimal voltages at very low or high temperatures.
The charger also features an automatic wake-up function for lithium batteries. When the Battery Management System (BMS) of a lithium battery goes into the protection mode, the charger can automatically activate the BMS and continue charging the lithium battery.
The charger is compact, light-weight and convenient to install and operate.
Installation
Install the battery charger as close to the target (OUT) battery as possible and keep the surrounding area clean, tidy, and well ventilated. This space should be moisture-proof, waterproof, and corrosion proof. Leave at least 10 cm of space around the charger to allow for proper airflow.
The recommended cable cross-section for "+" and "-" power cables is 1 mm2 cross-section for every 3A of maximum charging current. In any case do not use cables with lower current rating than the maximum charging current of the charger. In addition, to minimise the power loss and voltage drop, please do not exceed the maximum cable lengths referenced below:

Connection diagram
· Use as short cables as possible, especially between the charger and the target battery · The fuses need to be located within 15cm from the terminals of the batteries. Choose
the rating of the fuses according to the maximum charging current. · Ensure the positive and negative poles are not reversed or short-circuited · Always connect the cables to the charger terminals first before connecting them to
the battery terminals, to ensure you are not working with live cables
Source Battery
Target Battery
IMPORTANT! The charger requires a D+ signal to operate. If there is no signal applied to the D+ terminal, the charger will not turn on. If your system does not have a D+ signal, the D+ terminal can be wired directly to the positive terminal (12V +) of the source battery to turn the charger ON.
3
Green terminals
The charger features a pluggable terminal block of 4 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. Description of the terminal contacts is provided below.
"T T": these are the terminals for connecting an optional temperature sensor for measuring the temperature of the target battery.
If you install a temperature sensor in your system, please ensure that it is not affected by any heat source. Fix it on the case of the target battery or connect it to the negative terminal of the battery.
A temperature sensor is highly recommended for lead acid batteries in case if the ambient temperatures vary substantially from the baseline temperature of 25°C. The sensor performs two main functions:
· Charging voltage adjustment. The charging voltage for the target battery is compensated up or down depending on the ambient temperature to regulate the speed of chemical reaction inside the battery. The voltage will increase in the winter and decrease in the summer at the rate 18mV for each degree Celsius away from the reference temperature 25 °C.
· Battery protection. When the temperature is lower than -20°C or higher than 50°C, the charger limits the maximum charging current to 10A.
The charger can identify whether the temperature sensor is connected or not, or if it's damaged, short-circuited, or when an abnormal temperature is measured. In such case, the charger will automatically set the charging programme to the default temperature 25°C.
Note: there is no temperature compensation for lithium batteries.
"D+" : this is the terminal for connecting a "D+" signal (12V +) from the alternator, if the charger is used in a vehicle and the source battery (IN) is the vehicle's starter battery. This terminal controls the ON / OFF function of the charger. The charger will only operate at times when the alternator sends a "D+" signal to this "D+" terminal (when the alternator is working). The input voltage range for this signal is 8V 16V.
Alternatively, another connection option in a vehicle where the starter battery is used as a source battery, is to connect "D+" terminal of the charger to the 12V + signal from the ignition of the vehicle. In such case, if the ignition is ON, the charger will be ON and if the ignition is OFF, the charger will be OFF.
In a system without an alternator, this "D+" terminal should be connected to the positive 12V + terminal of the source battery to enable the charger to turn on. The charger will not operate if "D+" terminal is not connected. It is also possible to fit a suitable ON/OFF switch between the "D+" terminal and the positive 12V + terminal of the source battery to control the ON / OFF function of the charger.
"NC": this is reserved as a spare terminal with no function and no need to connect anything.

Charging process
Boost (constant current) charging stage: during this stage, the charger will charge the target battery with the maximum rated current until the target battery voltage reaches the boost voltage.
Absorption (constant voltage) charging stage: when the target battery voltage reaches the boost voltage, the charger will enter the absorption (constant voltage) charging stage. During this stage the charger will maintain the boost voltage and the charging current will gradually reduce. This stage will last for 1 or 2 hours depending on the battery type.
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 keep it full.
Equalisation: for selected battery types, the charger will perform equalisation charging by timer once a month with a higher charging voltage, in order to raise all battery cells to the same level. Equalisation charging will last for 2 hours. Please refer to the battery types table for details.
Note: if the target battery voltage is > 12.6V at the start of the charging process, the charger will not perform the absorption (constant voltage) stage and will instead charge to the boost voltage level and then go straight to the float charging stage.
Protection functions
Protection Target battery overvoltage Target battery low voltage
Description If the target battery voltage is > overvoltage protection voltage, the charging will stop. If the target battery voltage is > boost voltage value + 0.2V for 10 seconds, the charging will stop. Buzzer alarm: beeps once repeatedly for 1 minute If the target battery voltage is < low voltage alarm voltage, the buzzer alarm will beep twice repeatedly for 1 minute.

Source battery low voltage Overpower
Battery reverse polarity
Overheating (internal temperature)
If the source battery voltage is 11.5V-11.2V, the charging current is reduced to 10A. If the source battery voltage is < 11.2V, the charging will stop. The maximum charging current of the target battery is limited to 30A for DC1212-30S charger and 45A for DC121245S charger. If the target or the source battery is connected with a reverse polarity, it will blow the fuse inside the charger and may also cause hardware damage to the charger. Please contact the supplier of the charger with all the details, including which battery was connected with a reversed polarity. If the internal temperature is higher than 85°C, the charging will stop until the temperature drops to 60°C. When the temperature is > 80°C but less than 85°C, the maximum charging current is reduced to 25A for DC121230S charger and 37A for DC1212-45S charger. When the temperature drops to 65°C, the charging current returns to 30A/45A. Buzzer alarm: two consecutive beeps followed by a single beep repeatedly for 1 minute.
