Overload protection

105%-150% type: protection mode: automatic recovery after belching mode abnormal conditions are removed

Overvoltage protection

When the output voltages is more than 135%,close the abnormal output condition and restart it for recovery

Remarks

①Measurement of ripple and noise：Using a 12”twisted-pair line with a capacitor of 0.1uF and47uF in parallel at the terminal, the measurement is carried out at 20MHz bandwidth.

②Efficiency is tested at the input voltage of 230VAC,rated load and 25℃ambient temperature.

Accuracy: including setting error, linear adjustment rate and load adjustment rate.

Test method of linear adjustment rate：testing from low voltage to high voltage at rated loadadjustment rate test method: from 0%~100% rated load. The start-up time is measured in the cold start state, and the fast frequent switch machine may increase the startup time. When the altitude is above 2000 meters, the operating temperature should be lowered by 5℃/1000 meters.
