UNS0121A-ZV1 3BHE035301R1002 Controller Module  

Product Manual：

UNS0121A – ZV1 3BHE035301R1002 is an ABB UNITRAL1010 excitation controller module that implements generator excitation regulation, signal processing, and protection logic.

1. Built in PID algorithm to complete the excitation closed-loop voltage regulation of the unit
2. Collect voltage and current feedback signals and calculate reactive power
3. Electrical isolation channel to resist on-site electromagnetic interference
4. Overexcitation, underexcitation, overcurrent, PT disconnection fault protection
5. Rotating diode status monitoring, abnormal alarm output
6. Support dual channel, multi unit parallel load distribution
7. Modbus、 Ethernet communication, docking with DCS upper system
8. Output driving signal to control excitation power unit
9. Comes with a status indicator light for easy on-site troubleshooting
10. Hardware watchdog, automatic fault locking protection
11. Onboard storage, storing event and fault records
12. 24V DC power supply, low power consumption of the whole machine
13. Metal shell, dustproof, moisture-proof, and anti-interference
14. Modular structure, quick disassembly and replacement of spare parts
15. Industrial wide temperature range, suitable for long-term operation of small and medium-sized generator sets

UNS0121A – ZV1 3BHE035301R1002 is commonly used as the excitation device for hydroelectric, thermal, and self owned power plants, serving as the core control unit of the excitation system.
