Allen-Bradley 80026-044-02 IGDPS Board MV SMC Power Supply

Product Description

Overview

The Allen-Bradley 80026-044-02 is an isolated gate drive power supply board engineered for medium-voltage SMC (Solid State Motor Controller) systems. Designed for high-reliability industrial applications, it provides isolated power to gate drive circuits controlling IGCTs or SCRs. This board ensures precise triggering, smooth motor acceleration and deceleration, and reliable operation in demanding environments.

The module is epoxy-encapsulated to resist vibration, dust, and humidity, offering robust protection in mining, oil & gas, and heavy manufacturing applications. As a non-serviceable component, it is replaced as a complete unit if any output channel fails.

Key Features

• Provides isolated energy to IGCT and SCR gate drive modules

• Six independent 20V DC isolated outputs

• Compatible with 2300V, 3300V, and 4160V medium-voltage motor systems

• Epoxy-encapsulated PCB for environmental protection

• Converts 50V DC input into multiple isolated outputs for safe high-voltage operation

• Compact form factor suitable for dense control panel integration

Technical Specifications

Application Scenarios

Ideal for use in medium-voltage motor control centers requiring precise gate triggering for soft-start, linear deceleration, or pump control. Common environments include industrial manufacturing plants, oil & gas facilities, and mining operations where high reliability and long component life are essential.

FAQ
