DCx40 DC/DC Converters  
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  
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.  
DCD models: 24 Vdc, 18-32 Vdc; DCG models: 48 Vdc, 36-72 Vdc.  
Hold-upTime  
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.  
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-onTime  
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.  
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.  
Temperature Coefficient  
0.03%/°C typical on all outputs.  
Environmental  
No LoadTurn-on/Standby  
No degradation of reliability will occur; however, regulation may be  
affected.  
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.  
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%.  
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  
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.  
All DCx models are approved to UL 1950 (with no D4 deviations),  
CSA22.2 No. 234 Level 3, IEC950, EN60950.  
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
