As a professional manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing reliable and precise electrical protection solutions. Our Single Phase Voltage Protector with Digital Meter Relay is engineered to safeguard your valuable equipment from damaging voltage fluctuations. With a commitment to quality backed by certifications like ISO9001, we deliver products that ensure operational stability and peace of mind for businesses worldwide, from North America to Southeast Asia.
This advanced protector combines real-time voltage monitoring with robust protective functions. The integrated digital meter provides clear, accurate readings, allowing for immediate visual confirmation of line conditions. It is an essential component for maintaining the health of motors, compressors, and sensitive electronic systems.
- Precise Digital Monitoring: Features a clear digital display (LED or LCD) that shows real-time voltage values, enabling quick diagnostics and system checks.
- Dual Protection Modes: Offers configurable over-voltage and under-voltage protection. The device can be set to trip and disconnect the load when voltage exceeds or falls below user-defined safe thresholds.
- Adjustable Parameters: Key settings such as trip delay time, reset delay time, and voltage setpoints are easily adjustable via front-panel buttons or DIP switches, providing flexibility for various applications.
- DIN Rail Compatibility: Designed for easy installation on standard DIN rails, saving panel space and simplifying integration into control cabinets and distribution boards.
- Wide Input Range: Capable of monitoring a broad range of single-phase AC voltages, making it suitable for different regional power standards and industrial environments.
- Reliable Relay Output: Utilizes a high-quality electromechanical or solid-state relay with a robust contact rating to ensure dependable switching and long service life.

Frequently Asked Questions (FAQ)
Q1: What is a Mill Test Report, and why is it provided with this protector?
A: A Mill Test Report (MTR) is a certified document from the manufacturer that details the physical and chemical properties of the materials used and the test results of the finished product. We provide it to assure you of the product's quality, compliance with stated specifications, and traceability.
Q2: Can this voltage protector be used for three-phase systems?
A: This specific model is designed for single-phase AC systems. For three-phase applications, we offer dedicated three-phase voltage monitoring relays. Please inquire about our other product lines.
Q3: How do I set the over-voltage and under-voltage trip points?
A: The trip points are typically set using the front-panel interface. Most models have buttons to navigate menus and adjust values directly on the digital display. Refer to the user manual for detailed step-by-step instructions.
Q4: What is the response time when a voltage fault is detected?
A: The response time is configurable. You can set a trip delay (e.g., 0.1 to 10 seconds) to avoid nuisance tripping from short-term voltage sags or surges, ensuring the relay only activates for sustained faults.
Q5: Is the digital display readable in low-light conditions?
A: Yes, the digital meter is designed with high-contrast LEDs or a backlit LCD screen, ensuring clear visibility in various lighting environments commonly found in industrial settings.
Q6: What is the lifespan of the internal relay?
A: The relay is rated for a high number of mechanical operations (e.g., 100,000 cycles minimum under rated load). The actual lifespan depends on the switching frequency and load characteristics.
Q7: Do you offer custom voltage ranges or special calibrations?
A: As a manufacturer, we can provide customization options, including specific voltage ranges, special calibrations, or labeling. Please contact our sales team with your detailed requirements.
Q8: From which ports do you ship, and what are the lead times?
A> We ship from major Chinese ports including Shanghai, Tianjin, Guangzhou, and Ningbo. Standard lead times vary; please contact us for the most current information based on order quantity and destination.
