Product Overview

The Emerson Ovation 1X00797H01L serves as a high-capacity, industrial-grade power supply unit designed to energize Ovation and DeltaV DCS controllers, I/O modules, and field peripherals. This module converts unstable input sources into a regulated, low-noise 24VDC output. Delivering up to 20 Amps of current (480W), it supports heavy-duty automation loops where power consistency remains non-negotiable. We offer this unit as a 100% brand-new, original Emerson component to ensure maximum lifecycle and system integrity.

Technical Specifications

The 1X00797H01L utilizes advanced switching technology to achieve high efficiency and minimal heat dissipation within the control cabinet.

Engineering Advantages

• Redundancy and Fault Tolerance: This module supports parallel configurations for mission-critical nodes. In a redundant setup, if one power supply fails, the secondary unit assumes the full load instantly without dropping the controller's logic state.

• Fan-less Convection Cooling: The 1X00797H01L eliminates mechanical fans—the most common point of failure in power electronics. Its aluminum alloy chassis dissipates heat naturally, reducing maintenance requirements and preventing dust accumulation inside the unit.

• Superior Input Versatility: Unlike standard power supplies, this module accepts a wide range of both AC and DC inputs. This flexibility allows engineers to use the same part number across different plant sections, regardless of whether the local backup uses 110VAC mains or a 24VDC battery bank.

• High Efficiency (90%): By converting more power and wasting less as heat, this module allows for higher-density cabinet packing. It reduces the thermal load on adjacent I/O modules, effectively extending the MTBF (Mean Time Between Failures) of the entire control rack.

FAQs

• Can I use the 1X00797H01L in a hot-swap configuration?

  Yes. When installed within the appropriate Ovation power chassis or using external redundancy modules, this power supply supports hot-swapping. You can replace a faulty unit while the system remains live, ensuring zero process downtime.

• What is the significance of the 12–28V DC input range?

  This wide DC input range allows the module to function as a power conditioner or stabilizer. It can take fluctuating DC power from industrial batteries and provide a rock-solid 24VDC output to sensitive electronic components that cannot tolerate voltage dips.

• How should I orient the module during DIN rail installation?

  To maximize the benefit of natural convection cooling, always mount the module vertically with sufficient clearance (typically 50mm) above and below the unit. This allows cool air to rise through the internal heat sinks effectively.

• Is this module compatible with DeltaV systems as well?

  While primarily an Ovation series component, the electrical specifications and DIN rail form factor make it compatible with various Emerson-based automation platforms, including DeltaV, provided the power requirements match the 20A rating.
