Notes & safety
Notes: 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. Test by minimum Vin and constant resistive load.
5. Trimming allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an external resistor between the TRIM pin and either the +Vout pin or the –Vout pin.
6. The ON/OFF control pin voltage is reference to –Vin. Positive Logic comes standard and to order negative logic remote on/off add the suffix “R” to the model number.
7. Operating Temperature:
These converters can meet the railway T2 and TX temperature requirements.
T2: -40°C to +70°C for all models, TX: -40°C to +85 with power derating to 55% output power. (With heatsink the power derates to 70% output power).
Test conditions with vertical direction by natural convection (20LFM).
8. Heatsink is optional and P/N: 7G-0020C-F. See “Product Standard Table” on page 5 for ordering information.
9. EN55022 and EN55011
1) 24Vin and 48Vin Models: To meet Class B the modules do not need an external filter.
2) 110Vin Models: To meet Class A the modules do not need an external filter.
10. An external input filter capacitor is required if the module has to meet EN61000-4-4 and EN61000-4-5.
The filter capacitor suggested for 24Vin and 48Vin models is Nippon chemi-con KY series, 220μF /100V, ESR 48mΩ.
The filter capacitor suggested for 110Vin models is Rubycon BXF series, 100μF /250V.
11. There are several different options available for this series. Please see the “Product Standard Table” on page 4 for all options and ordering information.
CAUTION: This power converter is not internally fused. An input line fuse must always be used.
Due to advances in technology, specifications subject to change without notice.
Safety Approvals: UL60950-1, EN60950-1, IEC60950-1, EN50155 (Pending)
