supplies of power amplifiers, particularly those with toroidal
transformers and large smoothing capacitors, draw very high
current when switched on. This results in the premature rupturing
of the amplifiers' mains fuse.
The InRush Kit is the solution. On power up, a resistor limits
the high incoming current. After 1/2 sec, a relay shorts the
resistor, allowing the full mains supply to be applied to
the power transformer of the amplifier.
The onboard 12Vdc voltage regulator can be used to power the
Loudspeaker DC Protection circuitry of our 600Watts Hx350
Kit or any other accessories like the DCpro and exhaust fans.
