ABB SDCS-PIN-48-SD (COATED) 3BSE004939R1512 Pulse Transformer Board REV K
Product Overview
The ABB SDCS-PIN-48-SD (Part No. 3BSE004939R1512) is a rugged, DIN-rail-mount pulse transformer board that provides galvanic isolation, signal conditioning and PWM distribution for ABB DC drives and high-power converters. Engineered to operate in harsh industrial environments, the board delivers ±1 % accuracy across a 0–480 V AC output range while maintaining <2 ms response time, making it the critical link between the drive’s control CPU and the gate drivers of IGBT or thyristor power stacks.

Core Benefits
• Galvanic isolation prevents ground-loop noise and protects low-voltage control circuits from high-power switching transients .
• High-energy ferrite core design achieves low leakage inductance (<2 µH) and fast edge rates (≤100 ns) for precise PWM timing .
• Multiple secondary windings allow simultaneous drive of up to 6 power transistors with minimal phase shift .
• Hot-swappable DIN-rail installation reduces maintenance downtime; LED diagnostics provide instant module health status.
• Drop-in replacement for legacy SDCS-PIN-51 boards; fully compatible with ABB DCS 500/600, ACS 800 and Advant Master systems .
Typical Applications
• Rolling-mill DC motor drives (up to 1 MW)
• Excitation systems for synchronous generators (ABB EXC2000)
• High-voltage test benches and power supplies
• Mining conveyor speed control
• Printing line tension regulation
