marked to LVD

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: 1.3 A

Hold-Up Time

20 ms minimum from loss of ac input at full load, nominal line (115 Vac).

Output Power

40 W continuous, 50 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.

Main outputs: 124% ± 12%.

Efficiency

70% 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.

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%.

Remote Sense

Provided as a standard feature on single-output models.

Voltage Adjustment

Built-in potentiometer adjusts main output voltage ±5%.

EMI/EMC Compliance

All models include built-in EMI filtering to meet the

following emissions requirements:

EMI SPECIFICATIONS COMPLIANCE LEVEL

Conducted Emissions EN55022 Class B; FCC Class B

Conducted Emissions EN55011 Class B; FCC Class B

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

RF Field Susceptibility EN61000-4-3, 3 V/meter

Fast Transients/Bursts EN61000-4-4, 2 kV, 5 kH

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

Line Frequency Harmonics EN61000-3-2

Commercial Safety

Approved to UL1950, CSA22.2 No. 950, IEC950, EN60950. All dc outputs are SELV

under normal and single fault conditions.

Medical Leakage Current

The maximum leakage current is as follows:

Test Condition Normal Single Fault

120 Vac @ 60 Hz input 25 μA 35 μA

264 Vac @ 60 Hz input 40 μA 60 μA

Medical Safety

Approved to UL2601-1, CSA22.2 No. 601 Level 3 and EN60601-1. UL file E116994;

CSA #LR46516. The output(s) are intended for safety earthed Signal Output

and Intermediate Circuits only. The output(s) are not acceptable for patient con-

nection without additional isolation. 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
