  • Page 4: Functioning Description

    (sine waveform, music...), the diac obtains its reference level from a filtering network formed by a 100K resistor and a 1µF capacitor. The protections circuitry overhauls the MosFET's power consumption. Basically, this circuitry consists of two important sections: MosFET's Id current monitoring, and MosFET's Vds value detection. 52-0031-0100 EP04-05-05 DPA2500T DPA4000T Anglès.doc 1 of 2...
  • Page 5 The comparator (1/4 IC114) is responsible for the output shutdown relay performance, in order to close it as the temperature reaches 92ºC, and thus cutting of the amplifier's MosFETs bias current. As this happens, the signal output of the whole unit is cutted off. 52-0031-0100 EP04-05-05 DPA2500T DPA4000T Anglès.doc 2 of 2...

  • Page 30: Verification Process

    Once the nominal mains voltage is reached, wait for a minute and verify that the current consumption adjustments remain correct: 300mA for DPA4000T, 190mA for DPA2500T. If these values have changed, rectify them. Once adjusted, seal the potentiometer with fixing lacquer.
  • Page 31 LED lights up, output signal is cutted off, and the 10 seconds lasting STANDBY cycle is started. Wait until the STANDBY cycle ends, and allow the unit to repeat the process. Turn off the signal generator, output level set to minimum. 51-0153-0100 EP04-05-05 DPA2500T DPA4000T.doc 2 of 3...
