The VKC03 offers 3
watts of output power from a package in an IC compatible 24pin DIP
configuration. VKC03 series have 4:1 wide input voltage of 9~36 and 18~75VDC. The
VKC03
features 1600VDC of isolation, short-circuit protection and as well as five sided
shielding. All models are particularly suited to telecommunications, industrial, mobile
telecom and test equipment applications.

Note
The VKC03 series required a minimum 10% loading on the output to maintain specified regulation. Operation under no-load
condition will not damage
these devices, however they may not meet all listed specification.
2. Start up voltage 10 Vdc.
3. Please add an external filter at converter input terminals when measuring input reflected , figure 1.
L: Simulated source impedance of 12uH. C: Nippon chemi-con KMF series 47uF/100V.
4. The ON/OFF control pin voltage is referenced to –INPUT.
5. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment)
6. M1 version is more efficiency; therefore, it can be operated in a more extensive temperature range than standard.
7. Maximum value at nominal input voltage and full load of standard type.
8. Typical value at nominal input voltage and full load
9. Test by minimum input and constant resistor load.
CAUTION:
This power module is not internally fused. An input line fuse must always be used.
