SPECIFICATIONS

Ac Input

90-264 Vac, 47-63 Hz single phase. Class I or class II grounding.

Input Current

Maximum input current at 90 Vac, 60 Hz with full rated output load not to

exceed 0.6 A.

Temperature Coefficient

0.03% / °C typical.

EMI/EM Compliance

All models include built-in EMI filtering to meet the following EMC requirements of

IEC601-1-2.

Input Protection

Internal ac fuse provided on all units. Designed to blow only if a catastrophic

failure occurs in the unit -- Fuse does not blow on unsustained overload or

short circuit.

Inrush Current

Inrush is limited by internal thermistors. The inrush at 240 Vac, averaged over

the first ac half-cycle under cold start conditions will not exceed 37 A.

Overload Protection

Fully protected against short circuit and output overload. Short circuit protec-

tion is cycling type power limit. Factory set to begin power limiting at 23 W.

Overvoltage Protection

Built in OVP on all models. Approximately 120-140% of output voltage.

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.

Medical Safety Approvals

All models are Certified to be in compliance with the applicable requirements of

UL2601-1, IEC60601-1, CSA-C22.2 No. 601-1, EN60601-1.

Leakage Current

The maximum leakage current for GSM15 series will be as follows;

132Vac/60Hz UL2601-1 test method

Transient Response

Main Output - 500 μs max. 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 devia-

tion is 3.5%.
