The automatic power supply module, BKT60V50A, is a high-performance DC-DC buck-boost power supply, capable of raising or lowering the voltage according to needs.

It has a maximum power of 3000W and an adjustable current of up to 50A, making this module ideal for charging Li-Ion batteries, powering industrial equipment, solar, automotive or DIY systems.

The robust construction and efficiency of over 98% ensure stable operation and efficient heat dissipation.

The module offers precise voltage and current regulation (CC/CV), complete protection against overheating, short circuit, overvoltage and overcurrent, as well as automatic shutdown and controlled start (EN/ACC) function.

It is also equipped with a heatsink and supports the addition of a thermally controlled 12VDC fan for continuous operation at high loads.

Do not test the module with small laboratory power supplies (3A/5A) or electronic loads in DC mode.

Pinout:

PCB marking	Function	Detailed description
WIN+	Positive power input	Connects input voltage (9–58 V DC). Does not accept alternating current (AC). Be careful of polarity – reversing may damage the board.
GND	Common table (entry/exit)	Negative common pole for power and output. Must be connected firmly for stable operation.
VO+	Adjustable positive output	Adjustable output between 3 V and 56 V (depending on setting). Polarity must be respected.
RX1	Output voltage adjustment	25-turn potentiometer; rotate clockwise to increase output voltage (2.4 – 56 V).
X2	Output current setting	25-turn potentiometer; adjusts the current limit (5 – 59 A). Clockwise = higher current.
RX3	Input tracking voltage adjustment	Range 9.5–56 V. Used for sources with automatic tracking (e.g. solar panels, fuel cells). Clockwise → higher tracking voltage.
P1-1	External current control	Analog signal 0.26–1.25 V corresponding to 6–59 A. Requires input signal > 1 mA.
P1-2	EN (Enable) input	When connected to GND → the power supply stops completely (including the auxiliary board). Recommended for external controlled shutdown.
P1-3	GND control signal	Ground for external control signals (P1-1 / P1-2).
P2	12 V fan connector (optional)	Automatically activates the fan at 50–55 °C. Max. current. 0.3 A. Requires auxiliary power board.
P3	ACC (auto control) start	5–28 V for on/off control. A+ and A– for optocoupler control.
P4 (1-4)	Voltage/current display connector	An external voltmeter/ammeter or optional display module can be connected.
P5	External voltage control	Signal 0–2 V → output voltage 0–56 V (proportional). Recommended for microcontroller control.
P6	Auxiliary board power supply	14V input required for fan and display when connected.
LED1	Input voltage tracking indicator	On = activate input voltage tracking function (tracking mode).
LED2	Power/work indicator	On = the module is active and properly powered.
