DS3800NHVF1A1A | New Surplus GE Turbine Control Board

Description

Product Introduction

The DS3800NHVF1A1A is an enhanced version of the high-voltage frequency interface board—the NHVF with improved diagnostics. The suffix tells the story: the first “1” indicates a hardware revision with improved signal conditioning and isolation. The “A” specifies the standard configuration. The second “1” adds enhanced diagnostic features (configuration verification, frequency signal quality monitoring). The final “A” is the standard environmental package (no conformal coating). This board was designed for installations where better diagnostic feedback was needed for high-voltage frequency applications.

The enhanced diagnostics verify the board’s configuration and provide detailed status reporting on the frequency signals. Compare this to the base DS3800NHVF (standard diagnostics). The 1A1A gives you the same basic functionality with better diagnostic feedback.

Frequently Asked Questions (FAQ)

What’s the difference between the NHVF1A1A and the base NHVF?
The 1A1A adds enhanced diagnostics—configuration verification, frequency signal quality monitoring, and error logging. The base NHVF has basic link status only. The signal quality monitoring is useful for speed sensing applications—it gives you early warning of degrading frequency signals.

What’s the “Signal Quality” LED?
The Signal Quality LED indicates the integrity of the incoming frequency signals. The board monitors the signal amplitude, noise levels, and frequency stability. If the signal quality is good, the LED is green. If it’s marginal, it turns amber. If it’s poor, it turns red. This gives you early warning of sensor or cabling problems.

Do I need to upgrade my DMP firmware for the enhanced diagnostics?
The enhanced diagnostics require DMP firmware v3.0 or later. Older firmware won’t recognize the diagnostic registers. We can provide the firmware EPROMs if you need them.

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 your warranty and lead time?
We stock the NHVF1A1A 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.
