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.
