ABB 5SHX1960L0005 IGCT Gate Unit – Reliable, Fast Switching Control for Medium-voltage Power Converters

• Warranty: 365 days

• Lead time: 1 week if in stock; no more than 1 month at the latest

• Payment: 50% advance payment, full payment before delivery

• Express options: FedEx, UPS, DHL

• Dedicated IGCT driver – Designed to mate with ABB IGCTs for fast, reliable gate control and low switching losses.

• Fiber?optic firing interface – Noise?immune triggering and status feedback, which in many cases simplifies EMC and cabling in large cabinets.

• Integrated protection logic – Typically includes interlock, fault status output, and controlled turn?off to protect the semiconductor during abnormal events.

• High di/dt capability – Optimized gate drive to support the IGCT’s fast commutation characteristics in demanding converter stages.

• Serviceable design – Field-replaceable gate unit concept; you can swap a GDU without disturbing the power stack more than necessary.

• Proven in MV platforms – Commonly seen in medium?voltage drives, wind converters, STATCOMs, and rail traction where uptime is critical.

You’ll typically see the 5SHX1960L0005 in:

• Medium?voltage drives for compressors, pumps, and fans

• Reactive power compensation such as STATCOM and SVC systems

• Rail traction converters and marine propulsion drives

• Wind and photovoltaic central inverters using IGCT stacks

• Industrial UPS and energy storage converters with high cycling demands

• System reliability – Matched ABB driver-to-device behavior helps reduce nuisance trips and thermal stress on the IGCT.

• Compatibility – Seamless pairing with ABB IGCTs (5SHY series) and fiber?optic control schemes used in many MV platforms.

• Lifecycle cost – Stable availability and serviceable design can cut downtime costs compared with custom driver boards.

• Engineering support – ABB documentation and established application notes speed up commissioning and troubleshooting.

A maintenance lead from a steel mill told us the swap time “went from hours to under 45 minutes” after standardizing on ABB gate units across their IGCT stacks—seems to be a common theme when spares are aligned.

• Panel and cabinet – Use an IP54 or better cabinet in dusty/humid areas; maintain clear airflow around the power stack. Keep fiber bends within the recommended radius.

• Wiring and power – Provide a clean, regulated 24 VDC auxiliary supply with proper grounding. Route auxiliary and fiber separately from high?dv/dt busbars.

• Mounting – Follow ABB torque and clamping instructions to ensure correct pressure and alignment on the IGCT housing.

• Safety – Lockout/tagout the DC link; discharge capacitors fully. Verify fiber polarity and interlock chain before energizing.

• Routine care – Inspect connectors quarterly, check fiber cleanliness, and review thermal logs. Firmware/config (if applicable) should be kept at the recommended revision.

• Calibration/health – Periodically validate turn?off energy and gate current waveforms during service windows; abnormal signatures often indicate upstream issues.

• Manufactured under ISO 9001 quality systems

• CE compliance for applicable EMC/Low Voltage aspects at the assembly level

• RoHS compliant materials, typical for ABB semiconductor assemblies

• Warranty: 365 days

• ABB IGCT devices: 5SHY series (e.g., 4.5 kV / 6.5 kV classes)

• Fiber?optic transmitter/receiver modules and cables

• Snubber capacitors and clamp hardware specified for the target IGCT

• Auxiliary 24 VDC industrial power supply and interlock relays

If you need a cross?check on compatibility with your exact IGCT part number or a recommended spares list, share your converter topology and we’ll map the gate units, fibers, and accessories accordingly. You might notice that having matched pairs (IGCT + 5SHX gate unit) typically shortens commissioning time and reduces parameter tweaking.
