Description
Product Overview
The Emerson KJ3002X1-BG1 is a high-performance system power supply for DeltaV™ Distributed Control Systems. It converts bulk 24 VDC input into regulated 12 VDC and 5 VDC outputs to power controllers and I/O modules. Designed as a modular plug-in unit for DeltaV carriers, it provides reliable, low-noise DC power for critical process control operations.
Key Features
-
Dual-Voltage Output: Supplies stable 12 VDC for I/O modules and communication circuits, and 5 VDC for controller logic.
-
Redundancy Support: Compatible with 1:1 redundant configurations to maintain continuous system operation.
-
Active Load Sharing: Balances power between redundant modules to extend component life.
-
Diagnostic Indicators: Front-panel LEDs display power status, errors, and redundancy health.
-
High Efficiency Design: Convection cooling minimizes heat, eliminating internal fans and increasing MTBF.
-
Protection Circuitry: Built-in safeguards against over-voltage, short-circuits, and thermal overload.
