Output wiring method

Copper strip terminal, M5 nut seat，Need to use a power supporting copper terminal wiring

1. Efficiency This parameter is measured under 100% full load conditions, the efficiency is not a constant value (refer to the following efficiency VS load graph)

2. Wave and noise measurement Method: Use 12 "twisted pair, output terminal parallel 0.1uf and 47uf capacitors,  the oscilloscope bandwidth is limited to 20 MHz.

Output voltage regulation

Output voltage adjustable, Adj-V potentiometer manually adjustment )

Output current adjustment

The output current can be adjusted, the ADJ-A potentiometer manually adjusts, when the load reaches the current setting value, the constant current output (output current remains unchanged, the output voltage is reduced with the load)

Auxiliary voltage output

This machine provides a 12V-300mA auxiliary voltage output

PWM

Staggered parallel Two-transistor forword

Output short circuit protection

There is no output after the output is shorted, and the output voltage is automatically restored after short circuit release.

Output overload protection

The overload protection mode is constant current limit mode, the lock output current value is unchanged,

and the output voltage is increased and decreases with the load.

Overheating protection

When the heat sink temperature of the PWM transistor reaches 85 ° C ± 5%, the output voltage is turned off.

Automatic recovery when the temperature drops to 75 ° C ± 5%
