Reliable Three-Phase Protection

The EP9302 assures robust over and under voltage monitoring for three-phase systems within a voltage range of 300V to 470V. The device responds in less than 200ms, preventing damage to sensitive equipment through its precise, microprocessor-based design. Its adjustable settings enable tailored protection, guarding electrical installations from potentially harmful voltage fluctuations.

Flexible Installation and User-Friendly Operation

Featuring a DIN rail mount design, the EP9302 fits standard 35mm rails for effortless control panel integration. The high-grade ABS enclosure ensures safety, while screw terminals allow quick wiring. With selectable manual or automatic reset, as well as clear LED indication, operators benefit from straightforward usage and monitoring.

Engineered for Durability and Accuracy

Constructed to endure harsh environments, the EP9302 operates reliably between -10C and 55C, offering an IP20 level of protection. The 5A relay output supports a broad range of loads, while the compact form allows installation in tight spaces. High accuracy and fast response time ensure your equipment remains secure and steady.

FAQs of EP9302:

Q: How does the EP9302 protect equipment from over and under voltage conditions?

A: The EP9302 monitors three-phase input voltage, and if values deviate outside the adjustable trip settings (300415V for under voltage, 415470V for over voltage), it triggers the relay output to disconnect or signal the load. This rapid response prevents equipment damage from voltage fluctuations.

Q: What is the process for setting up the EP9302 in a control panel?

A: To install the EP9302, mount it onto a 35mm DIN rail within your panel. Connect the three-phase input and output devices to the screw terminals, set the desired trip and hysteresis points, and choose the reset mode (manual or automatic). Then, power the device with a 415V AC, 50Hz supply.

Q: Where is the EP9302 most commonly used?

A: The EP9302 is ideal for use in industries, commercial establishments, and infrastructure projects across India where protection of three-phase equipment from voltage fluctuations is critical, such as in motor control centers, distribution panels, and machinery automation systems.

Q: When should I use the manual versus the automatic reset function?

A: Manual reset should be selected when physical verification or safety checks are required before restoring power after a voltage anomaly. Automatic reset is best for applications needing quick, unattended restoration to minimize downtime after voltage levels return to normal.

Q: What are the benefits of the microprocessor-based design of the EP9302?

A: The microprocessor-based design enhances accuracy and speed, allowing precise monitoring and reliable operation under varying conditions. It also supports adjustable hysteresis and stable performance, reducing the risk of nuisance tripping.

Q: How is the relay output configured and what loads can it handle?

A: The EP9302 features a Single Pole Double Throw (SPDT) relay output with a current capacity of 5A (resistive load). The changeover contact allows connection to alarms, contactors, or control circuits that require isolation during voltage faults.
