VR195: Voltage Relay

- ป้องกันแรงดันไฟฟ้าเกินหรือตก

- ช่วยลดความเสียหายของอุปกรณ์ไฟฟ้าเนื่องจาก


- สามารถตั้งหน่วงเวลาได้ 0-10 วินาที

- มี LED แสดงสภาวะแรงดันไฟฟ้าตกหรือเกิน

           The Voltage Relay monitors the input voltage. The relay is energized and red LED. Lights up if the voltage is within the set-point limit. When the measured voltage moves outside the set-point limit, the relay will be deenergized. It is also fitted with an adjustable time delay to eliminate voltage fluctuations. The Voltage Relay can be used to protect against under or over voltage, to start up standby generators, to operate mains failure units, for switching standby hybrid supplies, protecting computer supplies and similar where close regulation is required.
