| Function & Details |
The DS200NATOG3A is a GE Mark V voltage feedback scaling board. Its core function is to safely and accurately convert the kilovolt voltage from high-voltage equipment such as generators and transformers into standard small signals such as 0-10V that the controller can recognize. This process relies heavily on the onboard precision resistor network. For example, the DS200NATOG2A can precisely scale down AC or DC high voltages up to 6900V to a safe range such as **0-10V**. Furthermore, while scaling the voltage, the DS200NATOG3A voltage feedback scaling board uses optocouplers or transformers to achieve electrical isolation between the high-voltage side and the control side, effectively eliminating ground loop effects and protecting expensive control components from unexpected high-voltage surges. The DS200NATOG3A voltage feedback scaling board supports multi-channel independent processing, capable of simultaneously handling three-phase AC voltage and positive and negative DC bus voltages.
The NATO board contains five identical sets of series precision resistors. Each set of resistors corresponds to one of the three AC phases, and the other two sets correspond to the positive and negative DC bus voltages, respectively. Each resistor group can be configured to attenuate input voltages of 6900, 4200, 3300, 2200, or 1200 volts by selecting three different input pin connectors and two jumpers. The outputs of the five resistor groups connect to a 20-pin flat cable connector. Metal oxide varistors (MOVs) prevent excessive output voltage in each resistor group when the input voltage is present and the output stripline circuit is interrupted. The load resistors are located on the gate distribution and status board, not on the NATO board.
Voltage feedback scaling boards are widely used in gas/steam turbines and power generation.
