90-264 Vac, 47-63 Hz single phase.
Maximum input current at 120 Vac, 60 Hz with full rated output load not to
exceed 1.3 A.
Normal continuous output power is 40 W for unrestricted natural convec-
tion cooling, 45 W peak for 60 seconds. During peak load conditions output
regulation may exceed total regulation and noise limits.
Regulation for multiple-output models measured by ±40% load change from
60% rated load with all other outputs at 60% full rated load and a line volt-
age change from low line to high line. Initial set tolerance is measured with
all outputs at 60% of full rated load. Output voltage V1 requires 1 A load for
proper regulation of multiple output models. Regulation for single-output
models measured by changing from 5% to 50% load or 50% load to full load
in either direction.
Factory set to begin power limiting at approximately 55 W. Fully protected
against short circuit and output overload. Short circuit protection is cycling
type power limit.
0.5% rms, 1% pk-pk, 20 MHz bandwidth, mode. Measured with noise probe
terminals of the power supply.
Main Output: 500 μs typical response time for return to within 0.5% of final
value for a 50% load step change, ∆i/ ∆t<0.2 A/μs. Maximum voltage devia-
tion is 3.5%. Startup/ shutdown overshoot less than 3%.
Built in on V1 with firing point set per table. OVP firing reduces output #1 and
#2 to less than 50% of nominal voltage in 50 ms.
