DC/AC converter function - GF54.10-P-2005FL

MODEL 212.0/2 up to 28.2.13 with CODE (U80) 115 V socket with CODE (460) Canada version with CODE (494) USA version as of model year 2011 /AEJ 10 

Function requirements, general 

• Circuit 15R ON

The electronic ignition lock control unit (N73) makes available the circuit status of circuit 15 via the interior CAN (CAN B).

DC/AC converter, general 

Only electrical small devices may be connected which require a supply with 115 V AC voltage.

The rear SAM control unit with fuse and relay module (N10/2) controls the function of the DC/AC converter control unit (N24/3).

The insertion of a 115 V-consumer in the 115 V power outlet (X58/34) is detected via the power outlet microswitch (X58/34s1). The rear SAM control unit supplies the power outlet microswitch with power.

If a consumer is connected to the 115 V power outlet, this voltage is switched through to the control input of the DC/AC converter control unit. The DC/AC converter control unit converts the DC voltage of the on-board electrical system into a 115 V AC voltage. An LED integrated into the 115 V power outlet indicates the availability of AC voltage.

The maximum available electrical continuous load is P = 150 W, for a short-term up to P = 300 W is permissible for t = 2 s.

If the interior temperature of the DC/AC converter control unit rises above a defined limit value or if the output load exceeds the overload threshold of P = 160 W for t = 2 s, the DC/AC converter control unit switches off.

A calculation method stored in the DC/AC converter control unit prevents the converter constantly switching between ON and OFF, when it moves in the proximity of the limit value.

If undervoltage is detected by the energy management system, the DC/AC converter control unit is switched off and the power supply to the 115 V power outlet is interrupted.
