900VPR-BL-U-CE

2,176.00

900VPR-BL-U-CE Digital Voltage Protection Relay is a versatile safeguard for electrical systems. Categorized as a Digital Voltage Protection Relay, it proficiently monitors critical parameters including Under Voltage, Over Voltage, Under Frequency, Over Frequency, Phase Asymmetry, Phase Failure, Neutral Loss, and Phase Sequence.

The relay is adaptable to both 3-phase 3-wire and 3-phase 4-wire configurations. Featuring a 3-digit Liquid Crystal Display (LCD) with backlight, it ensures clear information visibility.

For precise protection, the relay supports customizable trip settings. Under/Over Voltage trip settings range from 85V to 500V AC line-to-line (L-L) for 3-phase 3-wire connections and 50V to 288V AC line-to-neutral (L-N) for 3-phase 4-wire connections. Under/Over Frequency is within the range of 45-65 Hz, and Voltage Asymmetry ranges from 5.0% to 30.0%.

Time settings are also configurable, with Trip Time Delay spanning from 0 to 300 seconds, Power ON Delay from 0.5 to 300 seconds, and Recovery Time Delay in Auto Reset mode within the same range. The Response Time is impressively quick, clocking in at less than 120 milliseconds.

Precision is maintained with a ±1% ±2 digits accuracy for trip voltage, ±0.5% ±1 digit for frequency, and ±5% of setting ±120ms for time settings.

The relay offers two changeover output contacts (SPDT) for external system integration. It operates within an operating voltage range of 50V to 288V AC (line-to-neutral) and 85V to 500V AC (line-to-line).

With a compact size of 35mm and DIN Rail Mounting, installation is hassle-free. Holding the CE certification, it adheres to stringent safety and quality standards.

In summary, the 900VPR-BL-U-CE Digital Voltage Protection Relay is a dependable protector of electrical systems. Its versatility, accuracy, and certifications position it as a trusted guardian across a spectrum of applications.
