1. Introduction:

2. Product Features:

1. It adopts capacitive voltage divider + isolation structure, high precision, good linearity, small size, light weight, low power consumption, and ground impedance greater than 1000MQ.
2. -40C~+70C meets the requirements of class 0.5. There is no interface layering problem, safe and reliable. There is no ferromagnetic saturation and resonance,
3. There is no risk of explosion, shielding measures are taken, and the anti-interference ability is strong.
4. Isolation PT is used for isolation between primary and secondary, which is safe and reliable, and the load capacity is improved at the same time.
5. The output voltage is low, and there is no risk of secondary short circuit and large current
6. Installed at the plug position of the European plug-in plug, easy to install and does not take up space.
