Single Phase Over/Under Voltage Relay SVR1000 35mm Rail Walfront

Description

Product Overview

The Walfront SVR1000 is a single‑phase over‑voltage and under‑voltage monitoring relay designed for industrial motor protection. Housed in a compact 35 mm rail‑mountable frame, the device measures 3.35 x 2.36 x 1.97 inches and weighs just 4.23 ounces, making it ideal for dense control panels. Its universal AC/DC input automatically identifies the power type, eliminating the need for manual switching. An integrated LCD display, presented in Chinese characters, shows real‑time voltage values, fault status, and configurable parameters, providing operators with clear, at‑a‑glance information. The relay offers three reset modes—manual, automatic, and automatic with power‑on delay—allowing flexible response strategies tailored to specific operational requirements. Adjustable over‑voltage thresholds and programmable action times let users fine‑tune protection levels, while a built‑in fault‑recording function logs each event for later analysis. No auxiliary power supply is required, simplifying wiring and reducing overall system cost.

Usage

This relay is suited for a wide range of industrial environments where single‑phase motors are employed, such as pumps, compressors, fans, and small conveyor systems. It excels in applications that demand continuous voltage monitoring to avoid costly downtime caused by voltage spikes or drops. The rail‑mount design enables quick installation in standard DIN‑rail cabinets, while the universal AC/DC capability ensures compatibility with both legacy and modern power supplies. Engineers and maintenance technicians can benefit from the clear LCD readout and the ability to set precise voltage limits, making the SVR1000 an essential component for preventive maintenance programs. Its compact size also allows integration into space‑constrained control panels, and the fault‑recording feature provides valuable diagnostic data for troubleshooting recurring voltage issues.

FAQ

What types of voltage does the SVR1000 monitor?

The relay monitors both AC and DC voltages, automatically identifying the source and applying the appropriate protection parameters.

Can the relay be installed without an auxiliary power supply?

Yes, the SVR1000 operates directly from the monitored line, removing the need for a separate power source and simplifying wiring.

How does the fault‑recording function work?

Each voltage fault event is logged internally with a timestamp, allowing users to review the history of over‑voltage or under‑voltage occurrences via the LCD display.

Is the relay compatible with standard DIN‑rail panels?

Absolutely. Its 35 mm rail‑mount design fits standard DIN‑rail enclosures, making it easy to integrate into existing control cabinets.
