CSA-C22.2 No.950, EN60950
EN60601-1 and CSA-C22.2 No. 601-1
Ac Input
90-264 Vac, 47-63 Hz single phase.
Input Current
Maximum input current at minimum 120 Vac, 60 Hz with full rated output
load is 0.6 A.
Hold-up Time
15 ms minimum from loss of ac input at full load, nominal line (120 Vac).
Output Power
Normal continuous output power is 25 W, 28 W peak for 60 sec. maximum
duration, 10% duty cycle. Factory set to begin power limiting at approxi-
mately 30 W.
Output Regulation
Regulation from initial setpoint measured by changing load from 5% load to
50% load or 50% load to full load in either direction. Initial setpoint tolerance
is measured at 50% load. A minimum load of 5% of the output current on the
+5.1 V output (125 mA) is required to maintain proper regulation.
Overload Protection
Fully protected against short circuit and output overload. Short circuit protec-
tion is cycling type power limit
Output Noise
0.5% rms, 1% pk-pk, 20 MHz bandwidth, differential mode. Measured with
scope probe directly across output terminals of the power supply with load
terminated with 0.1 uF capacitor.
Transient Response
Main output: 750 μs typical response time for return to within 0.5% of final
value for a 50% load step within the regulation limits of minimum and maxi-
mum load, ∆l/∆t <0.2 A/μs. Maximum voltage deviation is 3.5%. Startup/shut-
down overshoot less than 2%.
Overvoltage Protection
Built in with firing point set per ratings table. OVP firing reduces voltage to
less than 50% of nominal voltage in 50 ms.
Voltage Adjustment
Factory set with fixed resistors to maximize reliability.
Efficiency
70% minimum at full rated load, nominal input voltage.
Input Protection
Internal ac fuse provided on all units.
SPECIFICATIONS
All specifications are typical at nominal input, full load at 25

Inrush Current
Inrush is limited by internal thermistor. The inrush at 230 Vac, averaged over the
first ac half-cycle under cold start conditions will not exceed 32 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 between 50 - 70°C. See Environmental and
Packaging Specifications on next page.
EMI/EMC Compliance
All models include built-in EMI filtering to meet the following emissions require-
ments:
