The FS Series of isolated, proportional DC to High Voltage DC Converters offers stout design and enhanced features for excellent long term reliability. Outputs ranging from 200 VDC through 6000 VDC are offered in miniature, cost effective, PCB mount packages.

The FS Series boasts a full ten watts of output power for each model and features a low 0.7 V turn-on voltage. The output voltage is proportional to the input voltage, from turn on to maximum output voltage, enabling easy control of the high voltage. A quasi-sinewave, resonant oscillator produces clean, reliable high voltage with inherently low ripple, low EMI/RFI, low input ripple current and low conducted emissions. The frequency of the oscillator is stable throughout the operating range, allowing for easy additional filtering and always operates well above the audio frequency range.

This series features sturdy, galvanic input to output high voltage isolation, conservatively rated at ±2500 V + Vout with less than 100 pF of coupling capacitance and less than 100 nA of leakage current. Robustness and high reliability have been designed in to each model by incorporating output arc surge current limiting and indefinite short circuit protection. Careful control over internal voltage gradients extends the useful life calculated. Mean Time Between Failure (per Bellcore TR-332) exceeds 840,000 hours.

In addition, the internal transformer temperature and input voltage are actively monitored with supervisory circuits and fed into a shut down circuit, preventing excessive input voltage or over temperature failures. Should preset limits be exceeded, the module will automatically shut down and issue an error signal on pin 6 (TTL high).
When the fault condition is removed, the unit restores itself to normal operation, ensuring maximum reliability in the field. However, the pin 6 error signal will remain high until reset by power cycling the +5 V logic.

The FS Series also features an Enable/Disable function. A TTL high signal on pin 8 disables the high voltage output.

High power conversion efficiency, coupled with low internal thermal resistance creates a vigorous package able to withstand wide operating temperatures. A unique integrated anodized aluminum heatsink surface features two threaded blind inserts which allow for optimal thermal management via external heatsink for high temperature operation and/or convenient chassis mounting configurations.
