Legend:
Yellow – Current Probe Measurement
Blue – Voltage Monitor Measurement
Red – Current Monitor Measurement
Yellow –.1V/A 6A @ .1 scale = 600mV
Blue
–.2V/V
1 Ohm @ 6A & .2 scale = 1.2V
Red –.5V/A
6A @ .5 scale = 3V
The output monitors are optically isollated and can
have 1us to 3us of transmision delay, see Figure 2.
The current measurement used for the output
monitor signal is taken before the output and its
compensation circuitry. An RC snubber circuit is
used to compensate for the inductive loading effects
caused by long cable lengths. The output lags the
current monitor because the compensation takes
some of the output inrush current, see Figure 4.
