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.

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:

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.

EMI SPECIFICATIONS

Conducted Emissions

Static Discharge

RF Field Susceptibility

Fast Transients/Bursts

Surge Susceptibility

Leakage Current

0.7 mA 254 Vac @ 60 Hz input.

COMPLIANCE LEVEL

EN55022 Class B; FCC Class B

EN61000-4-2, 6 kV contact, 8 kV air

EN61000-4-3, 3 V/meter

EN61000-4-4, 2 kV, 5 kH

EN61000-4-5, 1 kV diff., 2 kV com.

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.

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.

All specifications are typical at nominal input, full load at 25 O C unless otherwise stated
