The VFK400 series accepts an ultra-wide 4:1 input and can support either 10-36 Vdc or 18-75 Vdc isolated input voltages. The wide input range is very useful when being driven from a fluctuating device like a battery which can see both charging and discharging conditions. The DC-DC converter is offered in three different regulated output voltage versions: 12, 24, and 48 Vdc. High efficiency, fast response, tight regulations, remote sense and remote On/Off control make these converters very useful in many industrial and communications applications.
Standard features include over-temperature, over-current, and input transient voltage protection. With an external input fuse, the converter can also protect against accidental polarity reversal. The VFK400 series is available through Digi-Key at $388.94 for 500 pcs. Contact CUI directly for OEM pricing.
