Description

The Allen-Bradley 80026-044-02-R operates as an Isolated Gate Drive Power Supply (IGDPS) and switching power supply board optimized for high-power control systems. Engineered for integration within Medium Voltage (MV) solid-state systems such as PowerFlex drive networks and SMC motor controllers configured with optional soft stop, linear deceleration, or pump control capabilities, this IGCT board delivers a continuous, highly stable power feed to vital gate drive assemblies. The module adapts safely to high voltage compatibility thresholds including 2300 V, 3300 V, and 4160 V while managing internal processing operations via a 24 V DC internal distribution trace.

The 80026-044-02-R also coordinates tracking functions through a dedicated 0 to 10 V DC analog control signal infrastructure. To secure precise voltage regulation under harsh operational factors, the internal hardware component architecture is fully encapsulated in a ruggedized protective epoxy layer, isolating it against moisture and ambient contaminants. The specialized multi-channel layout delivers 6 isolated output channels fed from a master 50 V DC supply line, enabling independent drive path triggering across heavy industrial load networks.

Features

• Epoxy-encapsulated circuitry design preventing environmental contamination and enhancing sub-assembly insulation
• Six independent output channels supplying continuous power to downstream gate drive tracking components
• Localized status tracking via integrated diagnostics inside each output module channel box
• Highly adaptable high-voltage phase matching across 2300 V, 3300 V, and 4160 V system nodes

Applications

• Isolated gate drive power delivery within Medium Voltage SMC motor controller networks
• Switching power provisioning across 2300V to 4160V PowerFlex medium voltage control frameworks
• Automated acceleration, linear deceleration, and pump control gating loops

Installation Guidelines

• Non-Repairable Status: Do not attempt field repairs or localized circuit troubleshooting; because the board is completely encapsulated in epoxy, it features no internal test points or adjustments, and an individual channel breakdown requires a full unit swap.
• Diagnostics Verification: Check the internal green LEDs inside each of the 6 output module boxes during initial startup; an active illumination indicates a healthy +20 V DC state, whereas a dark LED indicates a drop below 18 V DC.
• Input Line Validation: If all 6 diagnostic LEDs fail to light, check the source feed lines with a precision meter to confirm that the input power checks at a steady 50 V DC, +/- 8 V DC.
• Atmospheric Boundaries: Install within standard control panels that prevent condensation, maintaining operating humidity under 80% and ambient temperatures between 0 and 40 Celsius.
