MODEL 204.9 with CODE (U80) 115 V power outlet in load compartment with CODE (460) Canada version with CODE (494) USA version 

MODEL 204.0 with CODE (U80) 115 V power outlet with CODE (460) Canada version with CODE (494) USA version as of model year 2011/YoM 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 small electrical devices that require a 115 V A/C voltage may be connected to the 115 V power outlet (X58/34).

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

Connecting a 115 V consumer to the 115 V power outlet is recognized by the microswitch power outlet (X58/34s1). The rear SAM control unit supplies the microswitch power outlet with power.

If a consumer is connected to the 115 V power outlet, this voltage is switched through to the control input for 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 from constantly switching between on and off when it gets close to the respective limit value.

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