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

MODEL 166 as of model year 2016 with CODE U80 (115 V socket) 

MODEL 292 with CODE U80 (115 V socket) 

Function requirements, general 

• Circuit 15RON

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

DC/AC converter, general 

Small electrical devices that require supply with U = 115 V AC voltage can be connected to the 115 V power outlet (X58/34).

The SAM control unit (N10) controls the function of the DC/AC converter control unit (N24/3). When a consumer is connected to the 115 V socket, it is detected by the microswitch power outlet (X58/34s1). The SAM control unit supplies power to the microswitch power outlet.

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 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 = 2s, the DC/AC converter control unit switches off.

A calculation method stored in the DC/AC converter control unit prevents the converter from constantly switching between on and off when it gets close to either 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.
