Protection

Output Over Power

144-180W Swing machine (Testing method: Increase the output current until enabling the protection. Protection mode:Swing machine, Self-recovery after over-power released.)

Output Over Voltage

57-70V Swing machine (Short circuit the Pin1-2 of U8, swing machine. Output recovery to normal after removing the short circuit) Note: Do not use external voltage.

Output Over Current

3-3.75A Swing machine (Testing method: Increase the output current until enabling the protection. Protection mode:Swing machine, Self-recovery after over-current released.)

Output Short Circuit

Use a copper wire with a sufficient cross-sectional area and a length of 15cm±5cm to directly short-circuit at the power output port, which can be short-circuited for a long time, and can be automatically restored after the short-circuit is eliminated.
