SPECIFICATIONS
Ac Input
85 - 264 Vac, 47 to 63 Hz.
Input Current
17 A line current maximum, at 90 Vac, 60 Hz with full rated load, power factor
.99 typical, .96 minimum. Input current harmonic content meets the require-
ments of IEC 1000-3-2 A14 for all load conditions.
Input Protection
Internal ac fuse provided on all units blows only on unit failure. (Additional
external fusing required for some medical applications.)
Turn-on
1.0 second maximum; overshoot < 2% at turn-on; < 1% at turn-off.
Hold-Up Time
21 ms minimum from loss of ac input at full load to the output decreasing
4%. Ac fail warning signal occurs at least 5 ms before the output decreases
4%.
Inrush Current
Inrush at 240 Vac is less than 37 A, averaged over the first ac half-cycle under
cold start conditions. Limiting provided by internal thermistors.
Temperature Coefficient
0.03%/oC, typical.
Transient Response
300 μs max. response time for return to within 0.5% of final value for a 50%
load change within the load range of 25% to 100%, with ∆i/∆t < 0.2 A/μs.
Maximum voltage deviation is 0.3%.
Overload Protection
Fully protected against short circuit and output overload. Power limiting is
cycling type with automatic recovery.
Reverse Voltage
Outputs protected against momentary reverse current not to exceed 20 A
peak for 10 ms max. with 0.5 A avg. Sustained reverse current at high levels
may damage unit.
Efficiency
Minimum value at full rated load, nominal input voltage. 48 V units 80%.
Medical Leakage Current
The maximum leakage current is as follows;
Conditions
132 Vac, 60 Hz
264 Vac, 60 Hz
Normal
90 μA
200 μA
Single Fault
80 μA
400 μA
EMI / EMC Compliance
All models include built-in EMI filtering to meet the EMC requirements of
IEC60601-1-2.
