GSM15 Medical
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.
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.
Efficiency
69-85% depending on model.
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.
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%.
Hold-up Time
10 ms minimum from loss of ac input voltage at full load, nominal line (120
Vac).
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.
