WH5D-2FF Emerson 1X00416H03 DeltaV Ovation Power Supply

Product Overview

The Emerson WH5D-2FF (part number 1X00416H03) is a high-efficiency, 100% brand new original industrial power supply module engineered specifically for Emerson DeltaV and Ovation Distributed Control System (DCS) platforms. This heavy-duty power component converts wide-range AC input voltage into a highly regulated, ultra-stable 24 VDC output to drive critical system controllers, I/O racks, and field instruments. By combining a dense 1500 W output profile with a rugged fanless design, this unit delivers uninterrupted power distribution to critical process loops without introducing mechanical failure points.

Engineering Advantages

The WH5D-2FF 1X00416H03 solves severe power quality and maintenance challenges found in large-scale manufacturing and automation plants:

• Eliminates Mechanical Fan Failures: Mechanical cooling fans represent the highest failure-rate component in traditional cabinet power units due to dust accumulation and bearing wear. This module utilizes an advanced fanless, natural convection layout that eliminates moving parts entirely, dropping maintenance overhead to zero and extending the operational lifespan inside sealed DCS enclosures.

• Maximizes Cabinet Density: Standard 1500 W power supplies often require deep, wide chassis that crowd industrial control panels. The compact 125 x 65 x 100 mm footprint packs high wattage into a fraction of the space, freeing up valuable rail room for additional I/O modules or termination blocks.

• Withstands Unstable Grid Voltages: Plant startup sequences and heavy motor lines cause extreme voltage sags and surges on the main AC line. The wide 85-264 VAC input window absorbs these massive voltage fluctuations natively, keeping the downstream 24 VDC control bus stable within a strict plus or minus 1% window to prevent controller reboots.

• Suppresses Signal Interference: Poorly isolated power units leak switching noise into analog I/O cards, distorting 4-20mA sensor readings. The integrated galvanic isolation and a low sub-100 mV peak-to-peak ripple threshold isolate high-voltage AC grid noise away from the sensitive low-voltage measurement backplane.

FAQs

• Q: Is this Emerson WH5D-2FF power supply a guaranteed brand new component?A: Yes. We supply this product exclusively as a 100% brand new, authentic original factory unit in original protective packaging, which fully satisfies utility validation guidelines and field-ready compliance checks.

• Q: Does this power module support parallel connection configurations for redundancy?A: The WH5D-2FF integrates seamlessly into standard DeltaV and Ovation power distribution structures. When mounted inside compatible power chassis, it supports N+1 redundant parallel wiring configurations to ensure the system keeps running even if an input line drops out.

• Q: What happens if a direct short-circuit occurs on the 24 VDC field side?A: The module activates its integrated short-circuit protection instantly, shutting down or current-limiting the output to protect the internal circuitry and the connected DCS hardware. The module resets automatically or safely recovers once the field wiring fault is cleared.

• Q: What mounting spacing rules apply to ensure proper cooling?A: Because this power supply relies on natural convection cooling, you must mount it vertically with the ventilation slots unobstructed. Maintain the standard recommended clearance gaps above and below the unit inside the enclosure to facilitate clean air circulation across the internal heat sinks.
