Myriad Dual-Phase Power Converter Installation Guide (MPN2805)

Overview

The Myriad Dual-Phase Power Converter (MPN2805) is designed to provide a stable 12V DC power output from two-phase AC input systems used in high-performance industrial and transport refrigeration environments.

Engineered for reliability and efficiency, the converter supports high-voltage input ranges and integrates battery monitoring and surge protection to ensure stable operation of connected electrical components.

This bulletin provides an overview of the converter specifications, installation requirements, and electrical connection guidelines.

Key Features and Performance

The Myriad Dual-Phase Power Converter offers reliable power conversion for demanding electrical systems.

Electrical Performance

Input voltage: 340–640V AC (two-phase input)
Output voltage: 12V DC
Maximum power output: 280W
Maximum output current: 20A at 14V DC

These specifications allow the converter to provide stable power for electrical control components and other low-voltage devices.

Converter Design and Dimensions

The converter is built for durability and easy installation within industrial and transport refrigeration environments.

Physical dimensions

Length: 242 mm
Width: 208 mm
Height: 133 mm

Mounting

The converter includes four oblong mounting points (10 × 20 mm) for secure installation.

Grounding

An M8 grounding stud is provided to ensure safe and reliable grounding during installation.

Electrical Connections

The converter uses dedicated connectors to ensure secure and stable electrical connections.

Input Connector

Amphenol AT04-3P-SR01BLK or equivalent connector

Output Power Connection

Standard M8 terminals used for power output distribution

Technicians should verify that all wiring connections are properly secured before powering the system.

Battery Temperature Monitoring

The converter includes an integrated battery temperature sensor designed to monitor battery conditions during operation.

This feature helps protect the battery system and ensures efficient power management, improving overall battery longevity.

Surge Protection Requirement

For safe system operation, the converter requires external circuit protection.

Install either:

4A time-delay fuse, or
4A circuit breaker

This protection helps prevent electrical damage caused by surge conditions or overload.

Two-Phase System Configuration

The power converter is designed for two-phase AC systems.

The converter does not require a specific phase order, allowing flexible installation within compatible systems.

This simplifies installation in industrial and high-demand environments where phase orientation may vary.
