TYPICAL SCR GATE VOLTAGE WAVEFORM
CONSTANT VOLTAGE INNERSHIELD
MAXIMUM OUTPUT SETTING – NO LOAD
0 volts
2 V | 5ms |
This is the typical DC open circuit voltage waveform. The machine was in an open circuit condition (no load) and operating properly. Note that each vertical division represents 2 volts and that each horizontal division represents 5 milliseconds in time.
Note: Scope probes connected at
SCR gate and cathode: (+) probe to gate,
