FEATURES
40 W dc/dc converter
Same size as ac input version
Drop-in replacement for GLC40 series
Two input ranges: 24 V and 48 V
Two-year warrranty
Full off-line isolation
Single and multiple output versions available
marked to LVD
SPECIFICATIONS:
Input
DCD models: 24 Vdc, 18-32 Vdc; DCG models: 48 Vdc, 36-72 Vdc.
Hold-up Time
6mSec minimum from loss of dc input at full load, nominal line.
Output Power
Normal continuous output power is 40 W (45 W Pk) for 60 sec.
Output Regulation
Regulation for multiple-output models measured by ±40% load
changeFrom 60% rated load with all other outputs at 60% full
rated load and a line voltage change from low line to high line.
Initial set tolerance is measured with all outputs at 60% of full
rated load. Output voltage V1 requires 20% load for proper
regulation of multiple-output models. Regulation for single-output
models measured by changing load from 5% load to 50% load or
50% load to full load in either direction.
Remote Sense
Standard on single-output versions. Capable of compensating for
0.25 V total of cabling losses in the output voltage.
Overload Protection
Fully protected against short circuit and output overload. Short
circuit protection is cycling type power limit on outputs #1 and #2;
foldback type on output #3. Factory set to begin power limiting at
approximately 55 W.
No LoadTurn-on/Standby
No degradation of reliability will occur; however, regulation may be
affected.
Output Noise and Ripple
0.5% RMS, 1.5% Pk-Pk, 20 MHz bandwidth, differential mode.
Measured with scope probe directly across output terminals of
the power supply with load terminated with 0.1 µf capacitor.
Transient Response
Main output; 500 µsec typical response time for return to within
0.5% of final value for a 50% load step within the regulation limits
of minimum and maximum load, i/t<0.2/µsec. Maximum
voltage deviation is 3.5%.
Overvoltage Protection
Built in on V1 with firing point set per output ratings table. OVP
firing reduces outputs 1 and 2 to less than 50% of nominal
voltage in 50 msec.
Voltage Adjustment
Factory set on standard units. However, optional potentiometer
adjusts voltage from 4.7 V to OVP point (6.2 V nominal) on the +5
V output. Note: output #1 must not be more than 1% below
nominal to achieve full output voltage range on output #2. Output
regulation limits in some models may be exceeded when the main
output is adjusted beyond +/- 1% of nominal voltage. See output
ratings chart for additional notes and conditions. High voltage
settings may degrade the reliability of the unit due to excessive
power dissipation in some outputs. Consult factory for application
assistance.
Efficiency
68% minimum at full rated load, nominal input voltage, depending
upon model and load distribution. Single-output models = 72% to
80% depending upon model.
Overshoot
Less than 3% at turn-on under nominal conditions, inversely
proportional to input voltage and temperature. Less than 2%
overshoot at turn-off under all conditions.
Turn-on Time
Less than 1 sec. At nominal line, 25°C (inversely proportional to
input voltage and thermistor temperature).
Input Protection
Internal fuse provided on all units. Inadvertent reverse voltage
application will blow fuse without risk of fire or shock hazard.
Otherwise, internal fuse is designed to protect against cata-
strophic circuit failures. Fuse does not blow on overload or short
circuit.
Inrush Current
Inrush is limited by internal thermistors to 22 A pk @ 24 Vdc and
44 A pk @ 48 Vdc.
Temperature Coefficient
0.03%/°C typical on all outputs.
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 Packing Specification on next page.
Storage
-40 to +85 °C.
EMI Compliance
All models include built-in EMI filtering to meet or exceed the
emissions requirements of FCC Class B. CISPR 22-Class B.
Typical margins >3dB at all frequencies and line/load conditions.
Safety
All DCx models are approved to UL 1950 (with no D4 deviations),
CSA22.2 No. 234 Level 3, IEC950, EN60950.

A.To maintain these regulation conditions, the 5.1 V current must be at least 20% of V2 and not greater than five times the V2 current, and requires +5.1 V to be adjusted within ±1%, with at least a
0.4 A load.
