Tomzn Tovpd160ec Manual Better [updated] Link

TOMZN TOVPD1-60-EC is a DIN-rail mounted protection relay designed to safeguard electrical appliances from voltage surges (over-voltage), sags (under-voltage), and over-current conditions. РКС Компоненти - РАДІОМАГ Key Technical Specifications Power Supply: 230VAC, 50/60Hz. Max Loading Power:

The device uses standard top-inlet, bottom-outlet logic for DIN-rail distribution boards. Incorrect wiring can instantly destroy the internal sensing circuit. tomzn tovpd160ec manual better

| Problem | Probable Cause | Solution | | :--- | :--- | :--- | | | No power on input side or internal fuse blown. | Check upstream breaker. Is the incoming L-N voltage present? | | Constantly clicking on/off | Voltage is bouncing at the trip threshold (e.g., 172V - 178V). | Increase the LUP (Under-voltage) hysteresis by setting the delay longer. | | Trips during lightning, but not heavy load | Over-voltage setting is too low (below 270V). | Set OUP to 280V. Lightning surges are nanoseconds; the delay will ignore them. | | Unit is hot to the touch | Normal up to 50°C (122°F) at 160A. | If over 60°C, you may have loose terminals or you are exceeding 160A. | | Screen works, but no output | Unit is in "Wait" mode (Voltage is safe, but counting down delay). | Look for a countdown timer on screen. Wait 30 seconds. | TOMZN TOVPD1-60-EC is a DIN-rail mounted protection relay
