SPECIFICATIONS
Ac Input
85-264 Vac, 47-63 Hz single phase.
Input Current
Maximum input current at 120 Vac, 60 Hz with full rated output load: 1.5 A
Hold-Up Time
20 ms minimum from loss of ac input at full load, nominal line (115 Vac).
Output Power
50 W continuous, 60 W peak. Peak ratings are for 60 s maximum duration,
10% duty cycle. During peak load condition, output regulation may exceed
total regulation limits.
Overload Protection
Fully protected against short circuit and output overload.
Short circuit protection is cycling type power limit on outputs 1 & 2; foldback
type on output 3. Recovery after fault is automatic. See output ratings chart
for additional notes or conditions.
Overvoltage Protection.
Crowbar provided on V1.
Efficiency
65% at full rated load, nominal input voltage, depending on model and load
distribution.
Turn-on Time
Less than 1 second at 120 Vac, 25°C (inversely proportional to input voltage
and thermistor temperature).
Input Protection
Internal ac fuse provided. Designed to blow only if a catastrophic failure oc-
curs in the unit.
Inrush Current
Inrush is limited by internal thermistors. Inrush at 240 Vac under cold start
conditions will not exceed 34 A.
Temperature Coefficient
0.03%/°C typical on all outputs.
Environmental
Designed for 0 to 50°C operation at full rated output power; derate output current
and total output power by 2.5% per °C above 50°C. See Environmental and
Packaging Specifications on next page.
Output Noise
0.5% rms, 1% pk-pk, 20 MHz bandwidth, differential mode. Measured with noise
probe directly across output terminals of the power supply.
Transient Response
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 deviation is 3.5%.
Startup/ shutdown overshoot less than 3%.
Voltage Adjustment
Built-in potentiometer adjusts voltage ±5% on outputs 1 & 2.
EMI/EMC Compliance
All models include built-in EMI filtering to meet the following emissions require-
ments:

Safety
Approved to UL1950, CSA22.2 No. 234 Level 3, IEC950 and EN60950; UL file
#E135803 commercial; CSA #LR46516 all models. All DC outputs are SELV under
normal and single fault conditions.

A. Total regulation is defined as the maximum deviation from the nominal voltage for all steady-state conditions of initial voltage setting, input line voltage and
output load.
B. To maintain these regulation conditions, the 5.1 V current must be at least 1/4 of V2 and not greater than 5 times the V2 current.
C. Requires +5 V to be adjusted within ±1% with at least a 0.4 A load to maintain regulation on this output since its centering voltage tracks the V1 adjustment.
D. Requires +5 V to have at least a 0.4 A load.
E. Add “G” suffix to part number for RoHS compliant model. Contact factory for availability.
