DS3800NHVM | New Surplus GE Turbine Control Board

Description

Product Introduction

The DS3800NHVM is a high-voltage measurement interface board for Mark IV systems—the “H” in the suffix indicates high-voltage functionality, the “V” indicates voltage, and the “M” indicates measurement. This board provides isolated high-voltage measurement connectivity for voltage sensing and monitoring applications in turbine control systems. It was used in installations where high-voltage measurements needed to be interfaced with the Mark IV control system.

The board plugs into the Mark IV backplane and provides a high-voltage measurement interface with electrical isolation to protect the backplane from voltage transients. Compare this to the DS3800NHVD (high-voltage digital interface) or the DS3800NHVL (high-voltage line interface). The NHVM is specifically for high-voltage measurement applications where isolation and protection are critical.

Frequently Asked Questions (FAQ)

What does the NHVM board do?
The NHVM is a high-voltage measurement interface board for Mark IV systems. It provides isolated high-voltage measurement connectivity for voltage sensing and monitoring applications.

What’s the difference between the NHVM and the NHVD?
The NHVM is specifically for measurement (voltage sensing, monitoring); the NHVD is a high-voltage digital interface. The NHVM has measurement-specific input capabilities; the NHVD has general digital I/O.

What’s the voltage rating of this board?
The voltage rating depends on the specific configuration. Check the board’s label or your system documentation for the exact voltage rating.

Can I hot-swap this board?
No. Mark IV backplanes are not hot-swappable. Power down the cabinet, lock out the breaker, and wait 60 seconds before removing or installing the board.

What’s the most common failure mode on the NHVM?
We’ve serviced about a dozen NHVM boards. The most common failure is the measurement input circuitry—it can degrade over time, causing inaccurate readings. The second most common failure is the edge connector—corrosion from humidity. The board is repairable.

What’s your warranty and lead time?
We stock the NHVM in limited quantities. Lead time is 1-2 business days. We offer a 1-year warranty. We test every board with a 24-hour burn-in and a diagnostic verification. The test report is included.

Is this board compatible with the Mark VIe?
No. This board is for Mark IV systems only. The backplane architecture is different.
