Shenzhen Sensor Electronic Technology Co., Ltd. products

CE-NT01 NB-IOT transmission terminal is an external terminal that uses NB-IOT network for wireless data transmission. It is small in size and supports online, hibernation and PSM mode automatic switching. It realizes ultra-low power consumption and supports COAP/UDP network. protocol. Users do not need to set up a server to fully support industrial configuration applications. Users do not need to care about complex network protocols. Through a fully transparent serial port, wireless data can be sent and received, allowing your device to access the Internet anytime, anywhere.

Background: With the rapid development of electronic technology, with the emphasis on external radiated interference (EMI) of electronic products, railways, electric power and other industries have clearly proposed technical standards and required mandatory implementation.

CE-D series 1-element digital display header (Figure 1) has the function of real-time LED digital display and setting the display ratio for the measured electrical parameters.

This series of products are high AC current measurement isolation transducer, the maximum measurable range is up to 3000A, completely isolated between the input and output, easy for installation, good security. The device can easily achieve the high current measurement, Compared to the transformer (CT) detection, there are obvious advantages on signal isolation and stability, and the standard output signal can be directly connected to the PLC. The product is quite suitable for electricity, communications, railways, industrial control and other areas of AC high current detection applications.

This device is an AC high current electrical isolation transducer, Its input and output are not common grounded. The input signal is AC current, and the output signal is standard signal of DC voltage or DC current. The product with the characteristics of high precision, high isolation voltage, low temperature drift, small size and easy installation. It can be widely used in communication, electricity, railways, industrial control and other fields.

The product is a zero sequence AC current isolation transducer, mainly used to measure the three-phase current phasor or current change of neutral line N (zero line) in three-phase four-wire circuit. Compared with the zero sequence current transformer (CT) detection, there are obvious advantages on signal isolation and stability, standard output signal can be directly connected to the host of the final stage control (such as PLC, etc.). The shell is made of flame-retardant ABS plastic shell. It adopts resin pouring, which effectively avoids the corrosion of transformer in the course of long-term use.

The high precision perforation type AC micro current isolation transducer developed by our company applies to microampere or milliampere AC current detection in various electrical systems, such as lightning arrester status detection ( good, lose efficacy, damage), a variety of electrical equipment, devices, instruments insulation and leakage current detection.
