Commercial Safety

All GLC models are approved to UL60950-1, CSA22.2 No. 950-95 3rd Ed, and

EN60950-1.

Medical Safety

All GLM models are approved to UL2601-1, CSA-C22.2 No. 601.1, EN60601-1.

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<0.2 A/μs. Maximum voltage deviation is 3.5%.

Startup/shutdown overshoot less than 3%. Turn-On Time less than 1 second at 120

Vac, 25.

Overvoltage Protection

Built in on main output.

Efficiency

72-85% depending on model.

Input Protection

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

failure occurs in the unit.

Inrush Current

Inrush limited by internal thermistors. Inrush at 240 Vac, averaged over the first ac

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

Temperature Coefficient

0.03%/°C typical on all outputs.

EMI/EMC Compliance

All models include built-in EMI filtering to meet the following emissions require-

ments:

Ac Input

90-264 Vac, 47-63 Hz single phase.

Input Current

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

exceed 2.9 A.

Hold-up Time

20 ms minimum from loss of ac input at full load, nominal line (120 Vac).

Output Power

Normal continuous output power is 75 W for unrestricted natural convection,

or 110 W with 26 cfm air flow.

Output Regulation

Load regulation on dual output models is measured by ±40% load change

from 60% rated load and input voltage change from minimum to maximum

ratings.

Output #1 requires 1A minimum load for proper regulation of other outputs.

Initial set tolerance is measured with all outputs at 60% of full rated load.

Load regulation for single-output models measured by changing load from

5% to 50% load or 50% to full load in either direction.

Voltage Adjustment

Output #1 adjustment is ±5%. Note: output #1 must not be more than 1%

below nominal to achieve full output regulation on output #2. High voltage

settings may degrade the reliability of the unit due to excessive power

dissipation in some outputs.

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 120 W.

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.

POWER FAIL

Power fail signal is TTL or CMOS compatible (output goes low <0.5 V) 5 ms

before output voltage drops more than 4% below nominal voltage upon

loss of AC power. The signal is factory set to trip on 84 to 94 Vac brown-out

depending upon incoming line impedance and distortion. Other settings are

available to the user through adjustment of built in potentiometer (consult

factory for assistance). Output will stay low for 20 ms minimum.
