DS3800NHVN | New Surplus GE Turbine Control Board

Description

Product Introduction

The DS3800NHVN is a high-voltage neutral interface board for Mark IV systems—the “H” in the suffix indicates high-voltage functionality, the “V” indicates voltage, and the “N” indicates neutral. This board provides isolated high-voltage neutral connectivity for field device termination and signal reference applications in turbine control systems. It was used in installations where high-voltage neutral signals needed to be interfaced with the Mark IV control system.

The board plugs into the Mark IV backplane and provides a high-voltage neutral interface with electrical isolation to protect the backplane from voltage transients. Compare this to the DS3800NHVL (high-voltage line interface) or the DS3800NHVJ (high-voltage junction interface). The NHVN is specifically for high-voltage neutral applications where isolation and protection are critical.

Frequently Asked Questions (FAQ)

What does the NHVN board do?
The NHVN is a high-voltage neutral interface board for Mark IV systems. It provides isolated high-voltage neutral connectivity for field device termination and signal reference applications.

What’s the difference between the NHVN and the NHVL?
The NHVN is specifically for neutral connections (signal reference, return paths); the NHVL is for line-level signals. The NHVN provides neutral termination points; the NHVL handles line signal distribution.

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 NHVN?
We’ve serviced about a dozen NHVN boards. The most common failure is the neutral isolation circuitry—it can degrade over time, causing leakage or grounding issues. 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 NHVN 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.
