GPC40 Commercial/GPM40 Medical
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%.
Eciency
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 Coecient
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.

EMI/EMC Compliance
All models include built-in EMI ltering to meet the
following emissions requirements:
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 le 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.
