GLC50 Commercial/GLM50 Medical
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 specied 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.
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.
Eciency
70-85% at full rated load, nominal input voltage, depending on model and
load distribution.
Minimum Load
Operating without minimum load will not degrade reliability, but regula-
tion may be aected. 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 rst ac half-cycle under cold start
conditions will not exceed 37 A.

Notes:
A. Total regulation is dened as the maximum deviation from the nominal voltage for all steady-state conditions of initial voltage setting, input line voltage and output load.
B. To maintain specied 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.
C. Add “G” sux to model number for RoHS compliant model.
