Description

18mm over and under voltage protector with over current protection
voltage and current display

General
TOVPD1-40M is a compact 18mm wide DIN‑rail protector that combines over‑voltage, under‑voltage, and over‑current protection in one device. It features a clear digital display showing real‑time voltage and current. All protection thresholds and delay times are user‑adjustable, including voltage calibration (±10%) and current calibration (±10%). When a fault occurs, the device automatically cuts off power and restores it after a preset delay once the condition returns to normal. Additional functions include fault inquiry (press UP >12s) and factory reset (press DOWN >12s). Ideal for household appliances, industrial panels, and electrical cabinets where space is limited.

Functions
1.Over-voltage protection
2.Under-voltage protection
3.Over-current protection
5.Voltage display(voltage measurement)
6.Current display(current measurement)
7.Voltage calibration:
Voltage ±10% adjustable. A13
Current ±10% adjustable. A15

8.Restore factory settings: press the down button for more than 12s
9.Fault inquiry: Press the UP button from more than 12S
