Basler 9284900103 Power Supply Module – Reliable Auxiliary Power for DECS-400N

The Basler 9284900103 is a dedicated power supply module that serves as the auxiliary power source for the DECS-400N digital voltage regulator. It converts a wide range of AC inputs into stable, isolated DC voltages to energize the regulator's control electronics, communication interfaces, and relay coils.

Design and Compatibility

This module is specifically designed to work with the DECS-400N platform, providing the exact voltage rails required for optimal performance. It features a switching-mode power supply that accepts both 120 VAC and 240 VAC inputs (nominal) with a tolerance of ±20%, covering global power standards.

Technical Specifications

• Input Voltage: 100–277 VAC, 50/60 Hz, or 120–300 VDC (universal)

• Outputs: +5 VDC / 3 A, ±15 VDC / 1 A, 24 VDC / 2 A (isolated)

• Efficiency: > 85% at full load

• Isolation: 2500 VAC between input and outputs

• Protection: Overvoltage, overcurrent, and short-circuit protection on all outputs

• Operating Temperature: -40°C to +75°C

• Dimensions: 4U high, half-rack width

Features

• LED indicators for input power and output status

• Remote enable/disable control input

• Parallel operation capability for redundancy (with external diodes)

• Conformal coated PCBA for humidity and dust resistance

Installation

The module is designed for 19-inch rack mounting or chassis mounting using provided brackets. All connections are via front-accessible screw terminals. The input and output circuits are fused for protection.

Integration with DECS-400N

The 9284900103 supplies all necessary voltages to the DECS-400N, including a dedicated voltage for field drive circuits. It also provides power to optional communication modules and I/O expansion boards.

Applications

This power supply is used in power plants, industrial co-generation, and large marine installations where the DECS-400N regulator is deployed. It ensures stable operation even when the main AC supply experiences sags or surges.

Maintenance

The module is maintenance-free under normal conditions. Periodic visual inspection for dust and proper ventilation is recommended.

Compliance

Meets CE, UL 508, and IEC 60950 safety standards.

Conclusion

The Basler 9284900103 Power Supply Module is an indispensable companion to the DECS-400N voltage regulator, providing robust and clean power to ensure continuous generator control.
