Let's put aside any EMI concerns

EMI spectrogram of VDR+VFB bundle or VDR + suggested layout has full compliance with MIL-STD-461 CE102. Shielding PCB on the bottom side along with external synchronization ability of internal frequency for modules over 40 W eases to reduce EMI.

VDR converters are design to meet MIL-STD-461 CE102 whenever you use either VFB or suggested layout

The modules undergo special thermal and limit test including burn-in test with extreme on/off modes. Units have wide operating temperature range –60...+125 °С

Designed according to MIL-STD-461

Operating case temperature –60...+125 °C

Our long-term experience is embedded in high-efficiency and technically well-balanced modules. Even have compact size modules have output power up to 500 W
