This module allows to control the ignition of an amplifier. It has a standby, sotf-start, time delay and thermal protection function. It limits the current draw through the power supply capacitors and the transformer at start-up. It is connected directly to the 220V input. If no load is connected, you can find 220V at the output (capacitor in series).

When the soft-start is activated, the amplifier is powered through thermistors. After one second, the second relay switches on and connects the output directly to 220V.

Two mountable thermal sensors are also provided (with wiring) and trip at 75°C, allowing the power supply to be cut off instantly when this value is exceeded. A status LED is also provided, flashing when switched on and remaining lit when the module is in operation.
