The power source is a full-bridge power converter based on  a ETD49 core.


*The pulse modulator control circuit is provided by SG3525 and NCP5181 power mosfet drivers without power factor correction.


The SMPS800/1KW also features an advanced over-current protection which limits the output current  in case of temporary overload.

When the overload condition occurs for a longer time, the supply will enter hiccup mode until the overload disappears.


The protection is set at 9 Amps. The voltage drops from 120Vcc to 113Vcc in a full load.

Large capacitors low ESR from Nichicon are used in the secondary stage



This feature combined with large primary electrolytic buffer capacitors leads to the capability of delivering high dynamic headroom power to the connected amplifier.

The sound will never been the same again. It will be greater.
