DS3800NHVH1B1B | New Surplus GE Turbine Control Board

Description

Product Introduction

The DS3800NHVH1B1B is an enhanced version of the high-voltage H-Bridge interface board—the NHVH with extended temperature range, conformal coating, and improved diagnostics. The suffix tells the story: the first “1” indicates a hardware revision with improved isolation and output driver protection. The “B” specifies extended temperature range components. The second “1” adds enhanced diagnostic features. The final “B” is the conformal coating with humidity-resistant components. This board was designed for installations where extended temperature range, environmental protection, and better diagnostic feedback were needed for high-voltage H-Bridge applications.

The conformal coating provides protection against humidity and dust. The extended temperature range means the board can operate in uninsulated shelters or outdoor cabinets. Compare this to the base DS3800NHVH (standard temperature range, no diagnostics, no coating). The 1B1B gives you the same basic functionality with significant improvements in reliability and diagnostic capability.

Frequently Asked Questions (FAQ)

What’s the difference between the NHVH1B1B and the base NHVH?
The 1B1B adds enhanced diagnostics (configuration verification, output current monitoring), extended temperature range (-40°C to +70°C vs 0 to 60°C), and conformal coating. The base NHVH has basic link status only.

What’s the “Output Status” LED?
The Output Status LED indicates the health of the H-Bridge output drivers. The board monitors output current and voltage. Green means the outputs are functioning correctly. Red means an output fault—check the load and wiring.

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 NHVH1B1B 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.
