High Voltage Foot Heating AT CELDUC® RELAIS, DC POWER SWITCHING UNDER CONTROL !

50A-750Vdc fully protected HV DC SSR for controlling HV foot heaters supplied directly from the catenary Our IGBT based SDI SSR can switch 50 A @ 750 VDC nominal in a fast, reliable and safe way. In every situation, safety operation is preserved : • Built-in over-voltage protection for inductive DC supply lines (max L/R = 20ms), OV4 • Built-in load short circuit protection : by detection of IGBT saturation, short circuits on the load will block the unit, keeping it safe • Built-in over load temperature protection : should over-heating occur, the unit will automatically switch off • Status...

Compressors for hydraulic or pneumatic braking INNOVATION AND QUALITY ARE THE DRIVERS OF OUR THINKING AND DOING

Innovation, Performance and Design ! • This range is designed for all types of loads from 12 to 125A • Output voltage from 24 to 690VAC (600V - 1200V - 1600V peak) • TMS2 technology 4th generation with very long life time expectancy Hydraulic and pneumatic braking systems are composed of pumps and compressors. Our SSRs are used for controlling these compressors. Our okpac® range is one of the solution we offer but it all depends on system design, and electrical specifications vary with manufacturers. You can ask for our expertise! Other models available please visit our website

Tramway wheel greasing compressor FOR EACH APPLICATION, THE CORRESPONDING TECHNOLOGY !

DC Solid State Relays for motor control DC SSR - MOSFET Technology celduc® relais offers a complete range of DC solid state relays up to 1700Vdc, 0 to 150A for DC applications. Our DC SSRs are used to control wheel greasing compressors. This system is designed for lubricating wheel flanges of trams. The system works on the principle of applying lubricant mixture to the contact area of tram wheel flanges with rails by means of pressure air. Other models available please visit our website

Railway Switch-points heating WORLD LEADER IN SOLID-STATE POWER SWITCHING & CONTROL !

AC Solid State Relays In climatic regions which frequently experience temperatures below freezing, malfunction of railroad rail switch mechanisms is often a problem. Temperatures below freezing and accumulation of snow and ice result in malfunction of railroad switch mechanisms. The solution is railroad switch heaters. Our SSRs are used to control these electric switch heaters. As showed below, the system could be equipped, for automatic operations, with Rails Snow Detectors and temperature sensors. Outdoor sensor Snow detection unit Temperature sensor Switch point heating element To ensure...
