Description:
Full-bridge drive, full-bridge rectification, compared with other
dual-inductance two-stage boost architecture, greatly reduce the overall circuit ripple.Higher power efficiency (up to 93% in the best condition within 40 watts), and low heat generation of key power components on the circuit board.10-28v power supply corresponds to 8-165v output adaptive.The default lamp current is 248mA, but the lamp current can be adjusted to a maximum of 650mA as needed (the step-down type supports 500mA).The overall circuit is simple, with fewer components, fewer electrolytic capacitors, and low failure rate.Strong anti-interference, with various protections such as overvoltage and no-load, extremely solid.
Precautions:
The maximum power supply voltage should not exceed 28vWhen you feel that the brightness is not enough, try to increase the current before adjusting the multimeter to measure the output lamp string voltage V power P=V*l
(The output voltage is multiplied by the output current, the default output current is 248mA)(The output voltage is less than the input voltage, that is, the step-down method; the opposite is the step-up method) The step-up type should not exceed 40 watts, and the best control is within 32 wattsThe output current of the step-down type must not exceed 500mA (very critical)
