ABB 5SHX1960L0004-3BHL000390P0104 – IGCT Gate Driver Unit for Medium-Voltage Drives

The ABB 5SHX1960L0004-3BHL000390P0104 is an IGCT gate driver unit used in IGCT-based converter stacks, typically found in ABB medium-voltage drives. From my experience, this unit focuses on fast, reliable switching control with proper protection of the IGCT device, so you keep downtime low and field service straightforward. You might notice that most replacements are driven by preventive maintenance or stack refurbishments—this module is designed to slot in as a direct, like-for-like service part when the revision matches (P0104).

Order Placement Process and Guarantees

Key Features

• Optimized for IGCT stacks – Provides the drive signals and protection IGCTs require for reliable high-power operation.
• Fiber‑optic control interface – Typically uses fiber links from the drive control to reduce noise and improve isolation.
• On-board protection and diagnostics – Monitors switching conditions and reports status/ready/fault for safer operation.
• 24 VDC supply – Standard industrial power input simplifies cabinet integration and service.
• Drop‑in service replacement – Designed as a like-for-like part number; revision P0104 matters for compatibility in many cases.
• Built for harsh panels – Robust construction suited to MV drive cabinets with proper ventilation and creepage/clearance.

Technical Specifications

Application Fields

This gate driver unit is commonly applied in medium‑voltage AC drives and high‑power converter stacks built around IGCT technology. Typical use cases include:

• MV fan, pump, and compressor drives in oil & gas, power, water, and mining
• High‑power rectifiers and regenerative systems in heavy industry
• IGCT‑based STATCOM/FACTS and test benches where precise switching is needed

Advantages & Value

• Reliability – Purpose‑built for IGCT control with proper protection and isolation, lowering fault risk during transients.
• Compatibility – Matched to ABB IGCT stacks; the correct revision typically means quick swap with minimal rework.
• Reduced Downtime – Faster replacement and commissioning compared with retrofitting generic driver solutions.
• Cost Control – Extends stack life and avoids premature IGCT failures, which generally have higher replacement costs.
• Supportable – Clear fiber and power interfaces make field diagnostics and routine service simpler.

Installation & Maintenance

• Cabinet environment – Install in a clean, dry, ventilated MV drive cabinet. Maintain airflow and keep within the drive’s ambient spec.
• Wiring – Use a stable 24 VDC supply. Route fibers with minimum bend radius, keep power and signal separated to reduce noise.
• Safety – De‑energize and discharge capacitors before work. Respect creepage/clearance around the IGCT stack. ESD precautions are recommended.
• Mounting – Secure with correct standoffs and torque; verify all board‑to‑stack connectors are fully seated.
• Routine checks – Inspect connectors, fiber cleanliness, and cabinet dust levels during scheduled maintenance. Update to the same or approved successor revision (P0104 or as specified) when replacing.

Quality & Certifications

• Manufactured under ABB’s quality system (commonly aligned with ISO 9001)
• CE and RoHS compliance typically achieved at the drive/system level
• 365‑day warranty on supplied part

Related & Supporting Components

To help with planning, these are typical pairings we see in the field. Please confirm against your drive’s BOM:

• ABB 5SHY series IGCT modules (e.g., high‑voltage press‑pack IGCTs used in MV drives)
• ABB fast recovery diodes (press‑pack types commonly paired with IGCT stacks)
• Fiber‑optic transmitter/receiver kits for the drive control interface
• 24 VDC industrial power supplies for gate unit auxiliary power
• Snubber capacitors and stack hardware matched to the IGCT module rating
