GF54.10-P-2005GM DC/AC Converter Function

Function requirements, general
^ Circuit 15R
^ Microswitch socket (X58/34s1) in 115 V socket (X58/34) closed (115 V consumer inserted)
^ Electrical output supplied is less than or equal to the permissible continuous electrical output
^ Temperature inside DC/AC converter control unit (115 V socket) (N24/3) lies within permissible temperature range
^ Input voltage lies within the permissible voltage range U > 11.5 V and U < 16.0 V
^ After t = 2 s, the output load is P< 150 W

DC/AC converter, general
The rear SAM control unit (N10/8) controls the operation of the DC/AC converter control unit. If the function requirements are met, a 12 V control signal is sent via the microswitch socket in the 115 V socket to the control input of the DC/AC converter control unit. The microswitch socket integrated into the 115 V socket is only closed when a 115 V connector is inserted. This microswitch socket then actuates the DC/AC converter control unit, which converts the on-board electrical system DC voltage to a 115 V AC voltage.
An LED integrated into the 115 V socket indicates the availability of AC voltage.

The customer can use the 115 V powered socket 115 V to connect small electrical devices that require such an AC voltage (e.g. video game consoles, charger for mobile phone). The maximum continuous electrical load which can be supplied is P = 150 W.

If the temperature moves outside the permissible temperature range or the output load reaches the overload limit of P = 150 W, the DC/AC converter switches off.

A hysteresis algorithm in the DC/AC converter control unit prevents the converter from constantly switching between ON and OFF if the system is near the respective limit value.
