Overview
In environments where consistent 3-phase power is crucial, power outages or phase-related issues can lead to significant downtime, equipment damage, and financial losses. The TOMZN 100A 3 Phase Auto Phase Selector acts as a vigilant guardian for your electrical systems. It continuously monitors all three phases (R, Y, B or L1, L2, L3) and the neutral line. In the event of an abnormal condition – such as an over-voltage, under-voltage, phase loss, or incorrect phase sequence on the primary phase – it intelligently and swiftly switches the load to another healthy phase, ensuring uninterrupted power flow. Furthermore, its integrated overcurrent protection adds an extra layer of safety, preventing damage from excessive current draw. This intelligent device is a must-have for maintaining operational continuity and extending the lifespan of your expensive 3-phase machinery in Bangladesh.
Key Features of TOMZN TOVPD3-100VAYA 100A Phase Selector
The TOMZN 100A 3 Phase Auto Phase Selector is packed with features designed to deliver maximum protection and convenience:
- Automatic Phase Selection: Seamlessly switches the load to the best available healthy phase (R, Y, or B) in milliseconds, ensuring continuous power supply even if one or two phases become unstable or fail.
- Comprehensive Voltage Protection:
- Over Voltage Protection (OVP): Safeguards equipment from damage due to excessively high voltage, with an adjustable trip range of 230V-300V per phase.
- Under Voltage Protection (UVP): Protects against low voltage conditions that can harm motors and other sensitive equipment, with an adjustable trip range of 150V-210V per phase.
- Over Current Protection (OCP): Prevents damage from current overloads, with an adjustable trip threshold from 1A to 100A, making it suitable for a wide range of applications.
- Phase Loss Protection: Detects and acts upon the complete loss of one or more phases, critical for motor protection and preventing single-phasing issues.
- Phase Unbalance Protection: Monitors the voltage difference between phases and trips if the unbalance exceeds an adjustable threshold (e.g., 5-99V), protecting motors from overheating and premature failure.
- Phase Sequence Protection: Ensures correct phase rotation (R-Y-B) is maintained, which is vital for directional motors and sensitive equipment, preventing damage from reverse rotation.
- Real-time Digital Monitoring: Features a clear, high-brightness LCD display that shows live voltage (L-N), current, and frequency for each phase, allowing for immediate status checks.
- User-Adjustable Parameters: All protection thresholds (OVP, UVP, OCP, Phase Unbalance) and delay times (trip delay, recovery delay) are easily configurable via intuitive buttons, allowing customization for specific load requirements.
- Fault Indication: Provides clear indicators and error codes on the display to quickly identify the cause of any trip, simplifying troubleshooting.
- High Current Capacity: Rated for 100 Amperes, capable of handling significant industrial and commercial loads.
- DIN Rail Mounting: Designed for easy and secure installation on a standard 35mm DIN rail within electrical panels.
- Robust and Durable Construction: Built with high-quality components to withstand demanding operational environments and ensure long-term reliability.
