ODM Three-Phase Adjustable Voltage Protector with LED Screen Suppliers, Factory

The Adjustable Voltage Protector is an advanced electrical protection device designed to safeguard household and commercial appliances from voltage fluctuations. It automatically disconnects power during overvoltage (up to 300V), undervoltage (as low as 140V) or overcurrent faults and restores supply after a fixed 30-second delay when voltage normalizes. Unlike disposable fuses, it withstands 450V surge without damage, built with flame-retardant casing. With configurable settings, digital display and dual LED indicators, it ensures full automation without manual intervention, providing reliable protection for sensitive equipment and supports standard DIN rail mounting for easy installation.Over-Voltage ProtectionCut-off Protector

Core Protection & Intelligent Delay Function

1. Superior Self-protection Performance

Unlike destructible disposable fuses, this protector stays intact while cutting power to safeguard loads against surges up to 450V. Made of flame-retart housing, it is fire & rust resistant for extended service life.

2. Digital Display & LED Indicator

Digital screen with indicator lights enables straightforward real-time circuit status check.

3. Intelligent 30s Delay Auto-reclosing

It instantly trips upon over/under-voltage and overcurrent. After a fixed 30-second delay, it restores power automatically only if grid recovers; otherwise, it keeps waiting to avoid frequent switch damage to appliances.

Wiring Diagram

Wiring easily: power inlet on top, outlet at bottom, neutral wire on left & live wire on right. User-friendly connection design.

Frequently Asked Questions

How does the auto-reclosing function work after a fault trip?

When voltage or current exceeds the threshold, the device trips immediately to cut the circuit. Once conditions normalize, it initiates a delayed countdown (default 30 seconds, adjustable between 1–300S) before restoring connection. If the fault persists, it remains off to prevent appliance wear.

Can the overvoltage and undervoltage trip points be adjusted?

Yes. Overvoltage limits are user-adjustable within 230V–300V (or 240–300V depending on preset modes), and undervoltage limits can be set between 140V–210V directly through the digital interface.

What standard mounting method does this protector support?

It comes equipped with an integrated rear rail mounting clip designed specifically for standard 35mm DIN rail installations, fitting seamlessly into consumer distribution boxes.

What is the correct way to connect the input and output wiring?

The protector follows an intuitive top-in and bottom-out structure: the power supply inlet terminals are at the top and consumer load outlets are at the bottom, following a neutral wire on the left (N) and live wire on the right (L) configuration.

What current ranges are available for this series?

The system accommodates rated current loads from 1A up to 100A, featuring adjustable overcurrent limits typically ranged between 10A to 63A, with standard rating profiles available for 40A, 63A, 80A, and 100A setups.
