SPECIFICATION
The S.M.P.S will shut down automatically when the AC input voltage lower than AC 90 V.
The S.M.P.S output voltage will drop to very low when overload by overload protection.
The S.M.P.S should not be fired or emitted smoke by protection when the circuit is short.
The S.M.P.S will shut down automatically when output voltage is over 28.5V by overvoltage
protection.
The S.M.P.S build-in thermal protector, when the transformer over heat (raise to 105),the circuit
will be shut down by PWM IC thermal protector.
The S.M.P.S can be changeable output voltage by changeable slot.
