Application Scenarios

In a large-scale pulp and paper mill operating multiple ACS600 drives for their main paper machine, maintenance engineers faced intermittent gate driver failures traced to aging power supply boards. Replacing the failing units with the ABB NGPS-13C restored stable ±15V and -8V rails to the NGDR gate driver boards, eliminating the sporadic drive trips that had caused over 40 hours of unplanned downtime in the previous quarter. The coated version of the ABB NGPS-13C withstood the high-moisture environment of the paper machine room, providing a direct drop-in solution that required no cabinet modifications. Since the upgrade, the mill has maintained continuous operation of the main drive section, protecting the critical IGBT modules and extending their service life.

Technical Principles and Innovative Values

Innovation Point 1: Dual-Application Architecture
The ABB NGPS-13C is engineered to serve two distinct power supply roles across ABB’s product portfolio. In the ACS600 drive system, it functions as a gate driver power supply, delivering the precise ±15V and -8V rails required for reliable IGBT switching . In the Symphony Plus DCS ecosystem, it provides the 24V DC auxiliary power needed for S800 I/O modules and field devices . This cross-platform versatility simplifies spare parts management for facilities operating both ABB drive and DCS equipment.

Innovation Point 2: Conformal Coating for Environmental Protection
The ABB NGPS-13C features a conformal coating that protects the printed circuit board against dust, moisture, and chemical contaminants . This protective layer is critical in harsh environments such as pulp and paper mills, steel plants, and chemical facilities, where airborne contaminants can cause electrical tracking and premature failure. The coating extends the MTBF of the module, reducing unscheduled maintenance and replacement costs over the system lifecycle.

Innovation Point 3: Redundancy-Ready Design
For mission-critical applications, the ABB NGPS-13C supports parallel redundant operation . Two power supplies can operate simultaneously; if one fails, the other seamlessly takes over the full load, ensuring uninterrupted power to control electronics. This architecture is essential for power generation, oil & gas, and other continuous process industries where even a brief power interruption can result in significant production losses.

Innovation Point 4: High-Efficiency Power Conversion
With efficiency ratings of up to 98%, the ABB NGPS-13C minimizes energy losses during operation . This high efficiency reduces heat generation within the control cabinet, lowering cooling requirements and contributing to overall energy savings. The reduced thermal load also benefits adjacent components, extending the life of the entire control system.
