Product Introduction

ABB UNS2881B-P.V1 (part number 3BHE009319R0001) is a high-performance Power System Monitoring Unit (Measuring Unit Board, MUB) designed for ABB UNITROL 5000 excitation systems, ACS 6000 medium-voltage drives, and grid automation platforms. As a core front-end component for power system monitoring, it performs high-precision multi-channel voltage/current acquisition, grid synchronization, and safety-critical fault detection, delivering real-time, accurate data for closed-loop control and protection decisions. 100% original ABB, brand new, in stock for fast delivery

Key Features

• High-Precision Multi-Channel Monitoring Integrated 32-bit RISC processor and 16-bit ADC, supporting 16-channel simultaneous sampling of AC/DC voltage, current, and temperature. Completes full scan in 1ms with accuracy up to ±0.1%, enabling precise tracking of grid fluctuations and early warning of PT/CT faults.
• Power System Stabilization & Protection Built-in Power System Stabilizer (PSS) function to dampen grid oscillations rapidly. Provides rotating diode health monitoring for excitation systems and real-time PT failure detection, ensuring safe and stable operation of generators and power equipment.
• Industrial-Grade Reliability & Adaptability Wide operating temperature: -40°C to +85°C. Constructed with 4-layer PCB and high-temperature materials, IP20 protection, resistant to dust, vibration, and strong electromagnetic interference. Powered by 24VDC (±10%), low power consumption, suitable for 24/7 continuous operation in harsh environments.
• Dual Communication & Seamless Compatibility Equipped with fiber optic + RS-485 dual interfaces for high-speed, anti-interference data transmission to the main controller. Fully compatible with ABB UNITROL 5000, ACS 6000, and other ABB control systems; supports hot-swap for easy on-site maintenance without shutdown.
• Original Quality & Fast Delivery Genuine ABB original with CE/UL/CSA certifications. In stock, ships within 1–3 working days. Backed by 12-month warranty and professional technical support.
