1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40°C.
MIL-HDBK-217F Notice2 @Ta=25°C, Full load (Ground, Benign, controlled environment).
2. Typical value at nominal input voltage and no load.
3. Typical value at nominal input voltage and full load.
4. The ripple and noise of 48VDC output voltage models is measured with a 2.2μF/100V X7R 1812 MLCC;
The ripple and noise of all other output voltages is measured with a 4.7μF/50V X7R 1812 MLCC.
5. Test by minimum input and constant resistive load.
6. The CTRL pin voltage is referenced to –INPUT. To order negative logic remote on/off control add the suffix “R” to the model number.
7. Output voltage is adjustable for 10% trim up or -20% trim down of nominal output voltage by connecting a single resistor between TRIM and
+SENSE pins for trim up or between TRIM and -SENSE pins for trim down. To calculate the value of the resistor R
U
and R
D
for a particular
output voltage see page 5.
8. Maximum output deviation is +10% inclusive of remote sense and trim. If remote sense is not being used the +SENSE should be connected to its
corresponding +OUTPUT and likewise the -SENSE should be connected to its corresponding -OUTPUT.
9. (1) Thermal test conditions for vertical direction are by natural convection (20LFM).
(2) Heat sink is optional. See the “Product Options” table on page 6 for suffix options.
10. The DC100 series can only meet EN55022 Class A or Class B with external components added. Please contact factory for more information.
11. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. We recommend connecting one aluminum
electrolytic capacitor (Nippon chemi-con KY series, 220μF /100V, ESR 48mΩ) in parallel.
12. CASE GROUNDING: EMI can be reduced when you connect the four screw bolts to the shield plane.
13. This series comes with several different options: negative remote on/off control, heatsinks, pin length, thru-hole inserts, and terminal blocks. See
the “Product Options” table on page 6 for more ordering information.
14. This product is Listed to applicable standards and requirements by UL.

CAUTION:
This power converter is not internally fused. An input line fuse must always be used.
