Commercial Leakage Current

0.7 mA 254 Vac @ 60 Hz input.

Commercial Safety

Approved to UL1950, CSA22.2 No. 234 Level 3, IEC950 and EN60950. UL file #E135803 commercial; CSA #LR46516 all. The output(s) are intended for safety earthed Signal Output and Intermediate Circuits only. All dc outputs are SELV under normal and single fault conditions.

Efficiency

70% at full rated load, nominal input voltage, depending on model and load distribution.

EMI/EMC Compliance

All models include built-in EMI filtering to meet the following emissions requirements:EMI SPECIFICATIONS COMPLIANCE LEVEL, Conducted Emissions GPC80 EN55022 Class B; FCC Class B, Conducted Emissions GPM80 EN55011Class 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 kHz, Surge Susceptibility EN61000-4-5, 1 kV diff., 2 kV com. Line Frequency Harmonics EN61000-3-2 Class A

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. See Environmental and Packaging Specifications on next page.

Hold-Up Time

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

Input Current

Maximum input current at 120 Vac, 60 Hz with full rated output load: 2.3 A

Input Protection

Internal ac fuse provided. Designed to blow only if a catastrophic failure occurs 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.

Medical Commercial Safety

Approved to UL2601-1, CSA-C22.2 No. 601.1 Level 3 and IEC601.1. 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 connection without additional isolation. All dc outputs are SELV under normal and single fault conditions.

Medical Leakage Current

35 µA 254 Vac @ 60 Hz input.

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.

Output Power

80 W continuous, 110 W with air flow. 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 outputs 3 & 4. Recovery after fault is automatic. Factory set to begin power limiting at 120 W. See output ratings chart for additional notes or conditions.

Overvoltage Protection

Main outputs: 124% ± 12% typical.

Power Fail (optional)

TTL- or CMOS-compatible output goes low (

Remote Sense

Provided as a standard feature on single-output models.

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

Voltage Adjustment

Built-in potentiometer adjusts voltage ±5% on outputs 1 & 2.
