Description
Product Description
Overview
The KJ3002X1-BG2 is a high-performance power supply designed for the DeltaV™ S-series Distributed Control System (DCS). This modular unit converts 24 VDC field power into precise 12 VDC output for the LocalBus, ensuring uninterrupted operation of controllers and I/O modules. It is optimized for redundant configurations to maintain system reliability in critical applications.
Key Features
-
Redundant Operation (1+1): Supports dual-module setup for hot-standby operation. Failure of one module does not interrupt LocalBus power.
-
Precision Voltage Regulation: Maintains stable 12 VDC output, minimizing EMI and ripple for sensitive digital electronics.
-
Integrated Diagnostics:
-
Front-panel LED indicators (Green = OK, Red = Fault)
-
Software monitoring via DeltaV Diagnostic Explorer for predictive maintenance
-
Robust Environmental Tolerance:

FAQ
Q: Can this module be used in hazardous areas?
A: Yes, it is certified for ATEX Zone 2 and Class 1 Div 2 environments.
Q: What happens if one module in a redundant setup fails?
A: The second module immediately takes over the full load without interrupting LocalBus communication.
Q: Is the KJ3002X1-BG2 compatible with other DeltaV power supplies?
A: It is designed to operate with S-series power carriers and can be integrated with dual DC/DC power supply modules.
