Description: This very compact module is mainly intended for the high voltage power supply of tube amplifiers. It is inserted into the high voltage secondary of the transformer and delays, with an adjustable time, the application of the high alternating voltage to the amplifier circuits in order to give the tubes time to warm up.A low voltage pre-charge is performed to ensure a smooth final power-up.Its connection is easy and does not require any modification of the amplifier, it is simply inserted between the 2 output wires of the high voltage transformer and the input rectification circuit of the amplifier (2 input wires and 2 output wires). No electromechanical elements such as relays are used, hence: very high reliability, no wear, no switching noise, no sparks and no 'click' when stopping. Almost zero consumption (reactive energy) on high voltage and no heating.A LED diode lights up when high voltage is output.This module is suitable for an AC input voltage of 150 V to 450 Volts, i.e. approximately 200 to 650 V rectified, filtered.Other voltages possible on requestFeatures :Dimensions: 90 x 50 x 20 mmMaximum AC input voltage: 450 VoltsMaximum switched current: 2 AmpsNominal delay: 40 to 80 seconds adjustable by 10-turn potentiometerOther possible delays when changing a capacitor.Module-specific consumption: < 10 mA on high voltageThis very compact module is mainly intended for the high voltage power supply of tube amplifiers.
