ABB Bailey NSPS01 Power Supply Module for INFI 90 Control Systems

The NSPS01 delivers reliable DC power for ABB Bailey INFI 90 rack systems. This ABB unit converts AC line voltage to stable DC outputs for all connected modules. We engineered this power supply to maintain system operation during fluctuating line conditions.

Technical Specifications and Design Features

This power supply module weighs approximately 2.1 kilograms. Its dimensions measure 280 millimeters in height, 85 millimeters in width, and 280 millimeters in depth. The unit features a robust metal housing with integrated cooling fins for heat dissipation.

Engineers will appreciate the multiple output configuration of the NSPS01. This unit provides 5V DC for logic circuits, ±15V DC for analog sections, and 24V DC for field devices. Consequently, a single power supply supports all INFI 90 rack components.

Furthermore, the auto-ranging input accepts 100 to 240V AC without manual adjustment. This flexibility simplifies installation across different regional power standards. The NSPS01 delivers 110 watts of total output power for demanding system configurations.

Energy Storage and Power Protection

The NSPS01 includes a 2,200 µF capacitor bank for energy storage. This capacitor array provides 20 milliseconds of hold-up time during power interruptions. Consequently, the system continues operating through momentary voltage sags without resetting.

The module features built-in overvoltage and overcurrent protection on all outputs. This protection prevents damage to connected modules during fault conditions. Engineers can rely on this feature for long-term system reliability.

Interface and Installation Details

You can install this power supply module in any INFI 90 rack slot. The NSPS01 connects to the backplane through integrated edge connectors. A front-panel terminal block accepts AC input wiring from 0.5 to 2.5 mm².

The module includes LED indicators for input power and each output status. Green LEDs confirm normal operation of all voltage rails. A red LED alerts users to fault conditions or output overloads. These visual cues simplify troubleshooting and system verification.

Thermal Management and Reliability

The NSPS01 uses convection cooling with integrated heat sink fins. This passive design eliminates moving parts that could fail over time. The module operates reliably across a temperature range from 0°C to 55°C. For reference, other Bailey INFI 90 power components share this same form factor and mounting method.
