SR469-P5-HI-A1-E Generator Management Relay
Product Manual：
SR469-P5-HI-A1-E is a generator management relay/control relay unit used for generator and power system management. It is used to monitor the key state parameters of the generator and issue control signals or protective actions according to the set logic when needed. It is an important component of the generator protection and automation control system.
Application field
Automatic control system for generator set
Generator protection and monitoring system
Factory/Facility Backup Power Management
Generator control in uninterruptible power supply (UPS) system
Ship, mobile power supply and other power systems
Main functions and features
Generator status monitoring
Monitor key parameters such as voltage, current, frequency, phase sequence, overload, etc.
Relay output control
Triggering relay output when detecting abnormalities or setting conditions, used for starting/stopping, alarming, or fault switching.
High precision detection
Accurately measure key power parameters to improve protection and control performance.
Multiple protection logic
Supports protection functions such as overvoltage, undervoltage, overclocking, underfrequency, and phase imbalance.
modular structure
Designed for easy installation, replacement, and on-site maintenance.
Industrial grade reliability
Suitable for continuous operation and high vibration, electromagnetic interference environments.
working principle
Relays receive signals from generator sensors (such as voltage transformers, CTs, current/frequency sensors) → internal logic determines whether parameters are within the set range → triggers relay action when abnormalities are detected → outputs control signals for cutting off, alarming, or switching to backup power sources → simultaneously feeds back status information to the monitoring system.
