ABB XVC770BE101 3BHE021083R0101 is HVD Board Coated used for High-voltage frequency or transmission system
XVC770BE101 has these Technical Characteristics:
It boasts extremely high pressure division accuracy, typically within ±0.1%, ensuring the accuracy of voltage closed-loop control.
The response speed is fast, at the microsecond level, capable of meeting the dynamic adjustment requirements of high-voltage frequency converters.
The isolation strength is ≥ 2500V AC, meeting industrial safety standards.
It uses resistors with low drift coefficients (< 50ppm/℃), ensuring stability across the entire temperature range.
It includes built-in overvoltage clamping, reverse connection protection, surge suppression (varistors / TVS diodes), and other protection functions.
And Core function are below:
The high voltage (up to kilovolt level) in the frequency converter / high-voltage circuit is reduced to a low voltage signal that can be safely detected by the control system in a precise ratio. This function is called high-voltage signal sampling and voltage division;
It provides the control system with precise real-time voltage feedback, which is used for closed-loop regulation and voltage stabilization control of the output voltage.
It realizes electrical isolation between the high-voltage power circuit and the low-voltage control circuit, ensuring the safety of the control system.
It participates in the voltage monitoring, overvoltage detection and protection logic triggering of the high-voltage circuit.

Are you interested in the working principle of XVC770BE101
It can be summarized as precise resistance voltage division + electrical isolation + signal conditioning, which safely converts the kilovolt-level high voltage output by the frequency converter into a low-voltage signal that the control system can recognize.
A detailed introduction:
Following the voltage division law, it is essentially a high-precision, high-isolation, industrial-grade resistance voltage divider network that operates based on Ohm's Law. The following formula can be referred to:
For example: If the pressure ratio is 1000:1, when an input voltage of 1000V is provided, the output will only be 1V.
Following the four-step process principle:
- High-voltage attenuation (core voltage division)
High-voltage input → Precise high-voltage resistor network → Reduce the high voltage to millivolt/volt level low-voltage signal at a fixed ratio (such as 1000:1).
- Electrical isolation (safety barrier)
The attenuated signal → Optocoupler isolation / Isolation amplifier / High-frequency isolation transformer.
- Signal conditioning (purification and amplification)
The weak signal after isolation → Active filtering circuit + Instrument amplifier.
- Feedback output (closed-loop control)
The processed standard signal → Sent to the A/D sampling port of the main control board (CPU).
