Mains current
Maximum
Average
1.5 A at 240 VAC
3.15 A at 110 VAC
0.6 A at 240 VAC
1.3 A at 110 VAC
CIE input voltage and current (mains on) 24 VDC, 4 A
Power (mains on) 137 VA (24 VDC, 4 A)
CIE input voltage (mains off) 21 to 29 VDC
Note: At 28.5 VDC the control panel indicates a
high power voltage fault (possible system
overload).
Maximum ripple at full load 150 mVpp
Note: Ripple and noise are measured at 20 MHz of
bandwidth by using a 12-inch twisted-pair wire
terminated with a 0.1 µF and 47 µF parallel
capacitor.
