Ang GRV8-SV Voltage Sensing Relay nagmomonitor sa mga lebel sa voltage. Ito ay gumagana kung ang voltage ay masyadong mataas o mababa. Ito ay nagprotekta sa iyong equipment mula sa pinsala at nakakaprevent ng mahal na downtime. Ito ay idinisenyo para sa industriya, agrikultura, at transportasyon. Ang pag-mount nito sa DIN rail ay simple. Ito ay kumukuha lamang ng kaunting espasyo. Ang intuitive LCD ay nagpapakita ng data sa voltage. Ito ay nagme-measure ng voltage nang tumpak gamit ang true RMS. Maaari kang magtiwala sa kanyang accuracy at reliability.
Product Highlight:
Dual Voltage Protection: Nagbibigay ng seguridad laban sa over-voltage at under-voltage, panatilihin ang iyong equipment sa ligtas na operating limits.
True RMS Measurement: Nagbibigay ng accurate voltage readings na may ±1% precision para sa dependable monitoring.
Normal/Emergency Power Switching: Seamless transition sa pagitan ng mga power supplies, nagse-ensure ng walang interruption sa operasyon.
Real-Time LCD Display: Nagbibigay ng malinaw, instant visibility ng voltage levels at system status.
Compact Design: 2-module width na may DIN rail mounting para sa madaling integration sa control panels.
Ang GRV8-SV voltage sensing relay, kasama ang kanyang dual voltage protection, True RMS high-precision measurement, real-time LCD display, compact design, wide applicability, high durability, certified quality, at user-friendly features, ay ang ideal na choice para sa pagprotekta ng equipment mula sa voltage fluctuations at pag-ensure ng stable system operation.
