Product Introduction

ETCR1520 Ring Main Unit Wireless Phase Detector, also known as low-voltage nuclear phase meter, is used for ring network cabinet nuclear phase and phase, frequency, and phase sequence testing.The instrument can be in the nuclear phase in a very low voltage line, the nuclear phase voltage is 1V~600V, and the nuclear phase is 30 meters away.
ETCR1520 Ring Main Unit Wireless Phase Detector consists of a host, a detector, data upload software, USB communication cable, etc. The host adopts a 3.5-inch true-color LCD screen, which can display the phase, frequency, phase sequence and nuclear phase results on the same screen. The vector diagram indication and phase indication are clear and intuitive, and it has voice prompt functions such as “normal X signal, normal Y signal, in-phase, out-of-phase” to make the test easier and easier.Storage function, can store 200 sets of data, USB communication interface, store data and upload to the computer for historical data reading, viewing, saving, printing, etc.
1. Wireless transmission technology is used, the nuclear phase is separated by 30 meters, and the nuclear phase is accurate and easy to operate.
2. Voice broadcast function, voice prompt: “X signal is normal, Y signal is normal, in-phase, out-of-phase”.
3. Using a 3.5-inch LCD color screen, the phase, frequency, phase sequence, and nuclear phase results can be displayed on the same screen, and the dynamic vector diagram indication and phase indication are clear and intuitive.
4. Storage function, 200 sets of data storage.
5. USB communication interface.
6. Rechargeable lithium battery
