Product Description



250W Aluminum Substrate Boost Constant Voltage Constant Current Adjustable Power Supply Module LED Boost Drive


1.Synchronous rectification technology: new imported components, synchronous voltage regulator technology, very low heat, full
power , state stability;

Synchronous rectifier circuit is using the MOSFET to instead of the rectifier diode to greatly reduce the loss of the rectifier
and improve the efficiency of DC / DC converter.

2.SMT process: FR-4 multilayer lines, resistors, capacitors and switch MOS tube are SMD components with high integration, high
reliability, high stability.

3.Filter inductance capacitor: a number of ultra-low impedance ripple electrolytic capacitors, iron silicon aluminum magnetic ring
multi-wire inductors, low heat.

4.Intelligent protection: internal use of the United States imported smart chip, with intelligent overcurrent protection,
overheating protection, short circuit protection, instantaneous absorption.

First, the output voltage / current regulation method:

1. Adjust the RV1 potentiometer and set the output voltage to the voltage you need according to your battery or LED. For example,
10 strings of LED voltage are adjusted to 37V.

2. Adjust the RV2 potentiometer clockwise about 30 times, set the output current to minimum, connect the LED, and adjust the RV2
potentiometer to the current you need. For battery charging, after the battery is discharged, it will be connected to the output
and adjust the RV2 to the current you need. (Be sure to use the battery after charging to charge, because the battery is left in
the battery.) More, the charging current is smaller.) Please do not use short circuit to adjust the current. The circuit structure
of the boost module cannot be adjusted by short circuit.
