Soft Start / DC Filter



NewClassD Soft Start circuit prevents high inrush currents from big mains transformers, that will normally blow fuses, overload switches and stress the rectifiers and capacitors. With this soft start circuit, the mains is connected slowly and smoothly to the power supply preventing any problems.

The DC Filter conditions the mains power, and removes the DC component. This will stop your transformer from humming. (Mechanical Hum).

This 2011 model includes also an offline power controller, which can also function as mains switch. You can connect a pushbutton and an LED to a set of terminals, and use them to switch the amplifier on and off. These are of course offline, so no special safety precautions have to be observed.
The middle terminal of the mains input is [optional] earth connection for the Y mains filter portion. You can use it to connect your chassis to the earth of the IEC mains lead.



The connection is straightforward. Keep a distance from the edge of the PCB to the chassis, to allow for safe operation.
CAUTION! This module has LIVE Mains Voltage on it, and you should NEVER touch it when it is connected to the mains! Also be CAREFUL that no metal objects come near the module when in operation!

This module is specially adapted for use with NewClassD modules, since it has very short break-in time. (1 sec). It will work safely with transformers up to 2000VA. A special fused output for an AUX transformer is provided to allow connection of a Gate Drive transformer, in case a Gate Driver winding is not placed on the main transformer. It is essential that such a transformer has it's own fuse, since a 6.3 or 8 Amp main fuse will not blow in the event something is wrong with it. So therefore we have provided a separate fused output on the Soft Start module, to allow easy connection of such Gate Drive transformer. The use of a separate Gate Drive transformer is optional.

The Soft Start Module offered is a Combo of Soft Start / DC Filter (Both functions are on the board, with offline pushbutton switch function. Note the actual pushbutton is not included.
