SPECIFICATIONS
DC Power Supplies
Ac Input
90-264 Vac, 47-63 Hz single phase..
Input Current
Maximum input current at 120 Vac, 60 Hz with full rated output load: 1.5 A
Hold-Up Time
15 ms minimum from loss of ac input at full load, nominal line (115 Vac).
Output Power
50 W continuous, 60 W peak. Peak ratings are for 60 s maximum duration,
10% duty cycle. During peak load condition, output regulation may exceed
total regulation limits.
Output Regulation
To maintain specified regulation on multi-output models, output #1 load
power must be at least 1/5th of, and not greater than 5 times output #2 load
power.
Temperature Coefficient
0.03%/°C typical on all outputs.
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.
Transient Response
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/shut-
down overshoot less than 3%.
Voltage Adjustment
Built-in potentiometer adjusts V1 ±5%.
EMI/EMC Compliance
All models include built-in EMI filtering to meet the following emissions require-
ments:
Overload Protection
Fully protected against short circuit and output overload. Short circuit pro-
tection 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.
Efficiency
70-85% at full rated load, nominal input voltage, depending on model and
load distribution.

COMPLIANCE LEVEL
EN55022 Class B; FCC Class B
EN55011 Class B; FCC Class B
EN61000-4-2, 6 kV contact, 8 kV air
EN61000-4-3, 3 V/meter
EN61000-4-4, 2 kV, 5 kHz
EN61000-4-5, 1 kV diff., 2 kV com.
Minimum Load
Operating without minimum load will not degrade reliability, but regula-
tion may be affected. Multiple output models require 20% minimum load
on V1 for proper regulation. Single models require 5% minimum load when
a transient load greater than 30% is applied or removed, but will operate
without load.
Input Protection
Internal ac fuse provided. Designed to blow only if a catastrophic failure oc-
curs in the unit—fuse does not blow on overload or short circuit.
Inrush is limited by internal thermistors. Inrush at 240 Vac,
averaged over the first ac half-cycle under cold start
conditions will not exceed 37 A.
Commercial Leakage Current
160 μA 254 Vac @ 60 Hz input (with no deviations).
Commercial Safety
All GLC models are approved to UL1950, CSA22.2 No.
234 Level 3, IEC950 and EN60950.
Medical Leakage Current
100 μA 264 Vac @ 60 Hz input (normal conditions).
Medical Safety
All GLM50 models are approved to UL/EN/IEC60601-1, CSA22.2 No. 601.
All specifications are typical at nominal input, full load at 25 O C unless otherwise stated
