Product Description
Overview
The KJ1501X1-BC1 is a high-reliability Dual DC/DC Power Controller designed for the Emerson DeltaV™ S-series Distributed Control System (DCS). It regulates and distributes power to I/O and controller modules, supporting both 12 VDC and 24 VDC input systems. Engineered for industrial environments, it delivers stable outputs while maintaining system redundancy to prevent downtime.
Key Features
-
Dual Power Input & Redundancy: Handles two independent power feeds for fault-tolerant operation. Failure of one supply does not disrupt system functionality.
-
Energy-Limited Alarm Circuits: Supports Uo = 30 VDC, Io = 135 mA, ensuring safe operation in hazardous areas.
-
Hot-Swappable Design: Can be installed or removed following proper safety protocols without affecting other modules.
-
Environmental Resilience: Designed to endure shock (10 g, ½ sine, 11 ms), vibration, airborne contaminants (ISA-S71.04 Class G3), and wide temperature ranges (0–60°C operational).
-
Precise Power Conversion: Provides regulated outputs: +12 VDC at 13 A (12 V input), +12 VDC at 4.5 A (24 V input), +5 VDC at 2 A, 3.3 VDC at 2 A, with total output power up to 10 W at 60°C.
-
Hazardous Area Compliance: Certified II 3 G, Nemko No. 02ATEX431U, EEx nC IIC T4, with inductance Lo = 3.55 μH.
