Power supplies for railway applications

With a turn over of 7 million Euro in the field of railway power electronics, we belong to the leaders of this market segment.

SYKO today offers a comprehensive railway product range of superior-quality custom-tailored and standard components, PCB-modules 19"-rack systems, open frame & enclosed or chassis mountable solutions including switching regulators, regenerators, DC/DC converters, power supply units, and power 1ph/3ph inverters / frequency inverters. SYKO's products are characterized by extremely wide input voltage and temperature ranges, excellent interference suppression, multiple outputs, and mechanical robustness. They are compliant with the relevant standards, such as EN 60950, EN 55022.B, EN 50155/121, EN 61000-4-4/5, RIA 12, UIC 550.

The Regenerator topology runs successfully on contact line voltages 600V / 750V or UIC voltages 1000 VAC/16,3 Hz, 1500 VAC/50 Hz, 1500 VDC and 3000 VDC with the universal range 680 VAC to 5050 VDC plus extreme transients up to 2 kW with active PFC (SYKO Patent US 5.991.166 / D 195 15 210).

When the function-determining output voltage is to yield a one- or three-phase voltage, an inverter on 110V battery or a frequency converter on 400 VAC/3ph to 520VAC/3ph 65Hz and inverters on 750V traction line voltage with controlled amplitude or f/U-control up to 6,5 kVA is mastered.

Further highlights are the new designed 100W-class of 19"-rack-converters, 1ph/3ph-sive wave-inverters, start-up-power supplies and battery chargers on all UIC-voltages as very-wide-input converters up to 1,5kW.

As a customer-specific global supplier we deal with the innovative demands of our customers.
