Single-phase electric power conditioner MINISTATIC series

three-phase

This device is intended to limit transverse and common mode spikes exceeding the input voltage peak value. Transient voltage protection can also be effective on spikes of atmospheric origin over 6kV. RFI FILTERS They attenuate high frequency transverse and common mode interferences over 300 kHz. ISOLATION TRANSFORMER It is featured by low output impedance, insensitivity to load power factor, high attenuation and functional and dielectric isolation. The F thermal class transformer has a recessed concentric winding configuration to meet the impedance and power factor requirements. The double shielding allows a common mode attenuation higher than 110 dB up to 350 kHz and an insulation degree in compliance with relevant Standards. The creepage and clearance distances exceed 7 mm. The withstanding overvoltage at 50/60 Hz between primary and secondary exceeds 3750V. The isolation at fulmination pulse voltage is 8 kVolt. ELECTRONIC VOLTAGE REGULATOR The electronic voltage regulator stabilises the voltage permitting to attain, under every load condition, ±3% output voltage accuracy with very high efficiency without generating any EMI interference. Its main features are: response time lower than 2 ms/volt, insensitivity to load power factor, reduced dynamic impedance (0,5%), efficiency higher than 99%, “quasi-peak” output voltage sensing circuit which allows “data acquisition” in 10 ms and the compensation of wave form flattening caused by non linear loads, creepage and clearance distances exceeding 8 mm, mounting of power semiconductors with 2500 Volt internal insulation on isolated heatsinks.
