SPECIFICATIONS
Ac Input
90-264 Vac, 47-63 Hz single phase.
Transient Response
Input Current
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.
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).
Overvoltage Protection
Built in on main output.
Output Power
Normal continuous output power is 75 W for unrestricted natural convection,
or 110 W with 26 cfm air flow.
Efficiency
72-85% depending on model.
Output Regulation
Input Protection
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.
Internal ac fuse provided on all units. Designed to blow only if a catastrophic
failure occurs in the unit.
Inrush Current
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.
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.
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
EMI/EMC Compliance
All models include built-in EMI filtering to meet the following emissions require-
ments:
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.
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.
All specifications are typical at nominal input, full load at 25OC unless otherwise stated
