ABB UNS2881B-P,V1 3BHE009319R0001 MUB Printed Circuit Board Completed
Overview
ABB UNS2881B-P, V1 MUB is a printed circuit board for measuring and adjusting motor stator parameters. It can directly measure the voltage and current of three-phase motors, and then calculate parameters such as active power, reactive power, frequency, and effective values of current and voltage. this board also supports single-phase measurement and has additional inputs for monitoring the voltage and current of the tie line.
🚀Function & Features
Monitoring functions
- Power System Stabilizer (PSS): UNS2881B-P can quickly damp power system oscillations.
- Rotating diode monitoring: UNS2881B-P is used for diode health status diagnosis of indirect excitation system.
- PT fault monitoring (PT-fail): UNS2881B-P detects voltage transformer abnormalities in real time.
Power management
Internal voltage conversion: UNS2881B-P converts centralized 24V DC power supply to multiple voltages required by COB/FIO board.
Configuration and debugging
Software parameterization: UNS2881B-P sets all parameters through COB board (no hardware jumper).

Questions & Answers
💡 FAQ
Q: What is the brand?
A: ABB
Q: What is the type?
A: MUB Printed Circuit Board
Q: What is the warranty?
A: 1 year
Q: Where is the shipping location?
A: Xiamen
Q: What is the payment method?
A: T/T
Q: Why choose us?
A: The UNS2881B-P is part of ABB's MUB system. These specialized excitation measurement boards often have very long lead times from the factory-commonly 8-12 weeks or even longer-and can face obsolescence risks due to version upgrades. For critical scenarios such as emergency repairs or major overhauls in power plants, where a single day of downtime can cause significant losses, we have this model in stock for immediate delivery and can also provide technical verification.
