Walfront Overvoltage and Undervoltage Protector SVR1000 Relay 35mm

Description

Product Overview

The Walfront SVR1000 is a precision‑engineered overvoltage and undervoltage protector relay built for demanding industrial environments. Designed to slide effortlessly onto a standard 35 mm DIN rail, this unit combines robust construction with intelligent monitoring capabilities. The relay features a clear LCD display that continuously shows the measured voltage, fault status, and user‑defined parameters, allowing technicians to quickly assess system health without the need for additional diagnostic tools. Its universal AC/DC voltage compatibility eliminates the need for manual switching, simplifying installation and reducing the risk of wiring errors. The device incorporates 1 CO (common open) and 1 NC (normally closed) contacts, enabling direct integration into existing control circuits without requiring an auxiliary power source. This energy‑saving design not only cuts operational costs but also enhances overall system reliability.

Usage

Engineers and maintenance professionals will find the SVR1000 indispensable across a wide range of single‑phase applications. It is ideally suited for electric motors that drive compressors, blowers, and refrigeration units, where voltage fluctuations can cause premature wear or catastrophic failure. The relay also excels in HVAC installations, protecting central air‑conditioning units and fan coil systems from harmful voltage spikes and drops. In manufacturing settings, the SVR1000 safeguards machine tools and conveyor drives, ensuring consistent performance even when the power grid experiences instability. Its compact form factor allows for easy placement in control panels, and the rail‑mount design means it can be added to existing systems with minimal downtime. Whether deployed in a factory, a commercial building, or a remote industrial site, the SVR1000 delivers reliable protection that helps extend equipment lifespan.

Why Choose Us

Choosing the Walfront SVR1000 means selecting a product backed by rigorous quality assurance processes. Each relay undergoes comprehensive testing for temperature tolerance, electrical endurance, and mechanical durability, ensuring it meets or exceeds industry standards for phase monitoring relays. The use of high‑grade components, such as gold‑plated contacts and a reinforced housing, provides superior resistance to corrosion and wear, which translates into longer service intervals and reduced maintenance costs. Walfront’s commitment to customer satisfaction is reflected in its responsive technical support team, ready to assist with configuration, troubleshooting, and firmware updates.

FAQ

What types of voltage does the SVR1000 monitor?

The relay automatically detects both AC and DC input voltages, allowing it to protect equipment regardless of the power source type. Users do not need to set a separate mode for AC or DC operation.

Can the over‑voltage and under‑voltage settings be changed on site?

Yes, the SVR1000 features an intuitive LCD interface that lets technicians adjust threshold values and action times directly on the device, without the need for external programming tools.

Is an auxiliary power supply required for the relay’s contacts?

No additional auxiliary power is needed. The relay’s 1 CO and 1 NC contacts operate directly from the monitored circuit, simplifying wiring and reducing overall system power consumption.

What maintenance is required for the SVR1000?

Routine visual inspections are recommended to ensure the LCD remains clear and the contacts are free of debris. The relay is designed for long‑term reliability, so no regular calibration is necessary unless system requirements change.

How does the warranty coverage work?

Walfront provides a standard one‑year warranty covering manufacturing defects. Should any issues arise, the support team will guide users through troubleshooting steps and arrange repair or replacement as needed.
