Voltage Protection Relay Module VPR-009

Description

1. Product Overview

The Voltage Protection Relay Module VPR-009 is a precision-engineered protection device designed to safeguard critical industrial assets from voltage-related faults, including over-voltage, under-voltage, phase loss, phase reversal, and neutral disconnection . Deployed across motor control centers, conveyor systems, and automated process lines, this relay provides a fail-safe mechanism that isolates equipment during abnormal conditions, preventing costly downtime and damage. In an era of increasingly sensitive and expensive electrical machinery, the VPR-009 serves as a strategic component for operational continuity and risk mitigation, offering a superior return on investment through enhanced system longevity and reliability. Its advanced fail-safe operation and configurable settings deliver a commanding value proposition for enterprises prioritizing asset protection and production stability.

2. Key Specifications & Technical Characteristics

• Protection Functions: Comprehensive protection against Under Voltage, Over Voltage, Phase Unbalance, Phase Failure, Incorrect Phase Sequence, and Neutral Disconnection .

• Measurement & Accuracy: True RMS measurement with a tripping accuracy of ±3% of the nominal value, ensuring reliable and precise fault detection .

• Hardware & Mounting: Features a compact (18 x 90 x 66 mm), flame-retardant enclosure (IP20 front face) for standard 35mm DIN-rail (DIN50022) or wall mounting, ideal for space-constrained industrial panels .

• Output Contacts: Equipped with potential-free changeover relay contacts (1CO or 1CO+1CO) rated at 5A/250VAC for robust load switching or alarm triggering .

• User Interface: Front-adjustment potentiometers and DIP switches for easy on-site selection of nominal voltage, system type (3P3W/3P4W), and trip delay settings, providing installation flexibility .

• Environmental Durability: Certified for operation in harsh conditions with a wide temperature range (-10°C to +55°C), high immunity to shock (15g) and vibration, ensuring consistent performance in demanding industrial environments .

3. Core Industrial Applications

• Motor Protection: Prevents burnouts and winding damage in critical motors by instantly disconnecting power during voltage sags, surges, or phase imbalances, significantly reducing maintenance costs and unplanned shutdowns in heavy industries .

• Process Industry Automation: Maintains the integrity of continuous processes in sectors like chemicals, pharmaceuticals, and food & beverage by ensuring conveyor systems and mixing equipment operate within safe voltage parameters, thereby protecting product quality and preventing material wastage .

• Power Distribution Systems: Serves as a primary defense for sensitive control panels and distribution boards, preventing cascading failures and protecting downstream PLCs, drives, and instrumentation from mains disturbances.

• Superior Performance: The VPR-009 excels by offering a fixed 3% hysteresis for unbalance protection and instant tripping for phase reversal, features which are often optional or absent in competitor models. Its ability to disable undervoltage/overvoltage faults while maintaining other protections gives engineers unique control over their system logic .

4. Competitive Advantages

• Uncompromised Quality and Reliability: Manufactured under stringent quality control processes to meet IEC 61010-1-2010 safety standards, ensuring dependable, long-term performance. The “fail-safe” relay configuration (energized in healthy state) ensures the relay defaults to a safe condition in the event of internal failure .

• Strategic Sourcing Decision: Our robust supply chain guarantees consistent availability, minimizing lead times and inventory risk for global procurement teams. Direct sourcing capabilities provide a clear price competitiveness advantage over traditional distributors.

• Operational Efficiency: The high mechanical and electrical endurance (1×10⁷ and 1×10⁵ operations respectively) extends the service life of the component, reducing replacement frequency and lifecycle costs .

• Comprehensive Support: Backed by extensive technical documentation, application notes, and dedicated engineering support to assist with integration from specification to commissioning. The relay’s universal input voltage selection further reduces inventory complexity across different regional standards .
