Mobitronics Switching Supply

[mildew]

Mate has a 200 series diesel Cruiser with a 220v outlet plug in the rear at 100w. He has a Waeco CF50 with an external switching supply MS-50A which powers the fridge.

The problem is when he plugs the Mobitronics in to the 220v outlet in the vehicle there is no audible click to show it is turned on and working, hence does not power the fridge. However, when he plugs the Mobitronics into a GPO in the shed it works. We plugged my CF50 with its built in inverter into the 220V outlet in the vehicle and it worked.

Any clues as to what is going on?

Technical details of the MS-50A are;

AC input 100 - 240v AC 50/60Hz 3A
DC output 27VDC 6A 150W
DC Battery input 12/24 VDC 12A/6A
DC Battery output 12/24 VDC 12A/6A

Many thanks in advance.

Jeff -

The issue is the rear outlet is rated for 100w. 100w at 220v is 0.45 amps (at 100% efficiency).

Watts = Volts x Amps

The specs show AC input of 3 Amps, so it is likely the plug is becoming overloaded and the circuit breaker in the LC is tripping.

I wish we had the diesel versions of the 200 here.
