GE DS200GDPAG1AGC｜High Frequency Power Supply Board｜

1. Input power supply (jumper can switch AC/DC dual mode)
Communication input: 80-132 VAC, 28-66Hz
DC input: 105-140 VDC
Rated power of the whole machine: 600~700W
System auxiliary logic power supply: 15VDC (powered by the cabinet backplane Arcnet bus)

2. High frequency power conversion unit
Inverter operating frequency: 27kHz high-frequency inverter circuit
Isolation and voltage resistance: 2500Vrms optoelectronic isolation between the primary and multiple outputs, isolating strong and weak electrical crosstalk, ground loop interference
Full load conversion efficiency: typical 88%, output ripple ≤ 100mV peak to peak value
Voltage regulation topology: Buck synchronous voltage reduction and stabilization circuit, automatic compensation for output voltage fluctuations

3. Multi channel isolated output (powered by GGDA driver board)
50VAC high-frequency AC (driving isolation transformer winding)
120VDC High Voltage GTO Gate Drive Power Supply
6-way independent 24VDC isolated control power supply, single channel 0.8A
Multi channel control signal level auxiliary circuit

4. Fault diagnosis and hardware protection
Onboard 4 fault status LED indicator lights+2 neon tube power status lights
Fault response: overcurrent/short circuit hardware self-locking protection, action time ≤ 10ms
3 independent replaceable branch fuses, single channel faults do not affect the power supply of the entire machine
Real time uploading of fault codes to the Mark V main control HMI, generating timestamp fault logs
