NOTES:
1
DC BUS VOLTAGE AND CURRENT IS MEASURED AT POS & NEG
OUTPUT TERMINALS OF THE POWER SUPPLY MODULE.
2. CURVES SHOW REDUCTION IN TRANSFORMER SECONDARY VOLTAGE
AND THE DRIVE MODULE DC BUS VOLTAGE, DUE TO TRANSFORMER
INTERNAL LOSSES, AS BUS CURRENT LOAD INCREASES.
3. ALL DATA TAKEN WITH TRANSFORMER PRIMARY VOLTAGE HELD
TO 480 VAC 3 PHASE LINE TO LINE 60 Hz AND WITH SECONDARY
WIRED FOR 230 VAC LINE TO LINE NO LOAD.
