Output Noise
0.5% rms, 1% pk-pk, 20 MHz bandwidth, dierential 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 nal 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 ltering to meet the following emissions require-
ments:
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: 1.7 A
Hold-Up Time
20 ms minimum from loss of ac input at full load, nominal line (115 Vac).
Output Power
55 W continuous, 70 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 protec-
tion is cycling type power limit on outputs 1 & 2; foldback type on outputs 3
& 4. Recovery after fault is automatic. See output ratings chart for
additional notes or conditions. Factory set to begin power limiting at ap-
proximately 75 W.
Overvoltage Protection
Main outputs: 124% + 12%
Eciency
70% at full rated load, nominal input voltage, depending on model and load
distribution.
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 Coecient
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 Environmen-
tal and Packaging Specications on next page.
