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:
