Technical Specifications & Default Parameters Understanding the factory defaults of the TOMZN TOVPD1-60-EC tomzn tovpd1-60-ec manual
The is a high-performance, single-phase adjustable over-voltage, under-voltage, and over-current protection relay designed for DIN-rail mounting. It functions as an automated circuit defender by continuously analyzing grid conditions and cutting off power within milliseconds if anomalies are detected, thereby preventing destruction to domestic, commercial, or industrial electrical appliances. To customize the thresholds for your specific electrical
To customize the thresholds for your specific electrical ecosystem, you must enter the programming mode. Button Functions The device features a dual-display LED screen
Check local grid stability. If the grid safely fluctuates within slightly wider margins, consider adjusting A2 (Over-voltage) higher or A6 (Under-voltage) lower within safe appliance tolerances.
The device features a dual-display LED screen. Typically, the shows the current Voltage (V), while the bottom display shows the Current (A). There are three main buttons:
The LCD shows the present voltage and current simultaneously. A backlight makes the display readable even in dark electrical cabinets.
