DCx40 DC/DC Converters

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 Load Turn-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.
