As a professional manufacturer specializing in electrical protection solutions, Jinhua Dika Electrical Equipment Co., Ltd. proudly presents our Compact DIN Rail Mount Single Phase Over/Under Voltage Protector. Designed for 230V 50Hz systems, this device is engineered to provide reliable and precise protection for your valuable electrical equipment against damaging voltage fluctuations. With over a decade of experience and a commitment to quality underscored by our comprehensive management system certifications, we deliver products that ensure operational safety and continuity for our clients worldwide.
This compact protector is an essential safeguard for any electrical installation. It continuously monitors the supply voltage and automatically disconnects the load when the voltage exceeds or falls below preset safety thresholds, preventing potential damage to motors, compressors, HVAC systems, and other sensitive equipment. Its intelligent design allows for automatic reset once the voltage returns to a stable, safe range, minimizing downtime and manual intervention.
Key Features and Technical Advantages:
- Precision Monitoring: Utilizes advanced microprocessing technology for accurate real-time voltage measurement, ensuring fast and reliable response to anomalies.
- Compact DIN Rail Design: Its space-saving form factor allows for easy installation on standard DIN rails within control panels, cabinets, and distribution boards, optimizing panel layout.
- Wide Adjustable Range: Both the over-voltage and under-voltage trip points are user-adjustable, providing flexibility to match specific application requirements and local grid conditions.
- LED Status Indication: Clear visual indicators show power status and trip condition (normal, over-voltage, under-voltage), facilitating quick diagnostics.
- High Reliability: Built with robust components and subjected to rigorous testing, ensuring long-term stability and performance even in demanding industrial environments.
- Time-Delay Function: Incorporates an adjustable time delay for trip and reset actions, preventing nuisance tripping caused by short-term voltage sags or surges.

Frequently Asked Questions (FAQ):
-
Q: What is the primary function of this voltage protector?
A: Its core function is to monitor the single-phase AC supply voltage (230V/50Hz) and automatically cut off power to the load if the voltage rises above (over-voltage) or falls below (under-voltage) the user-defined safe limits, thereby protecting connected equipment. -
Q: How do I set the trip points for over-voltage and under-voltage?
A: The device is equipped with potentiometers or DIP switches (model dependent) for adjusting the trip thresholds. Please refer to the product manual for detailed setting instructions based on your specific model. -
Q: Does it have a manual reset function, or is it fully automatic?
A: It typically features an automatic reset function after the line voltage stabilizes within the normal range for a preset time. Some models may also offer a manual reset option; please confirm the specific features when inquiring. -
Q: Can this protector be used in three-phase systems?
A: This specific model is designed for single-phase systems (Line & Neutral). For three-phase applications, we offer dedicated three-phase voltage monitoring relays. Please inquire for suitable models. -
Q: What is the response time when a voltage fault occurs?
A: The response time is very fast, typically within milliseconds for detection, plus any user-set time delay. This rapid action helps prevent damage from transient spikes or dips. -
Q: Is the relay output contact normally open (NO) or normally closed (NC)?
A: The output contact configuration (1NO/1NC or changeover) is available upon request. Standard models often come with a changeover (SPDT) contact for flexible wiring into control circuits. -
Q: What are the installation requirements?
A: Installation requires a standard 35mm DIN rail inside an enclosure. Connection is via screw terminals for the power supply (L, N) and the output relay contacts. It should be installed by a qualified electrician following local electrical codes. -
Q: Do you provide technical support or customization?
A: Yes, as a manufacturer, we offer comprehensive technical support. We can also discuss customization options such as different voltage ranges, specific trip delays, or special labeling to meet your project's unique needs.
