Electrical/electronic transformer for converting supply voltage to load voltages has temperature-controlled device preventing overheating by reducing converter power if secondary side short-circuited

摘要

The device has at least one housing part for functional elements connected to the mains voltage on one side and connected to the load on the other side, at least one switched mode power supply stage with automatic short-circuit detection and at least one voltage converter with electrical isolation and a temperature-controlled closing device that prevents overheating by reducing the power in the converter if the secondary side is short-circuited. The electrical/electronic transformer has at least one housing part (1) for functional elements connected to the mains voltage on one side and connected to the load on the other side, at least one switched mode power supply stage (5) with automatic short-circuit detection (9) and at least one voltage converter (6) with electrical isolation and a temperature-controlled closing device (8) that prevents overheating by reducing the power in the converter if the secondary side is short-circuited.
