50v 450v Arası 500 mA Ayarlanabilir Güç Kaynağı

DİKKAT Devre yüksek voltaj ile çalışmaktadır dikkatli olun kondansatör bağlantılarına dikkat edin + – kutupları ters bağlarsanız yüksek voltajda büyük patlamalar olabilir devreyi çalıştırmadan önce Sigortalı Elektrik Hattı,koruyucu gözlük kullanın

HT Power Laboratory – range from 50 to 450 V – 500 mA alternatif link

Voltage adjustable from 50 to 450 volts in a current of 500 milliamps, with a stable 0.1% 100Hz ripple and noise factor: <1 mV pp on the range. The internal resistance is <0.5 ohm static and <1 ohm dynamics of 10Hz to 100KHz.

Warning:The conduct of this project requires experience and professionalism. Tensions are conveyed all dangerous, in the same way as those generated in tube amplifiers. Prudence donc ! Prudence therefore!
The circuit is composed of 3 sub-groups: the circuit switches, pre-regulation and regulation: block diagram The circuitry for issuing voltages +24 Vdc, +5 Vdc and -5 Vdc and allows the delayed entry into service of the main transformer of 400 VA. The map of pre-regulation issue in a low impedance (Z = 5 ohm), a voltage stabilized at 485 Vdc. The card issuing the regulation voltage controlled variable from 50 to 450 volts in a current of 500 mA max.
