current sensor AC DC transmitter aperture 35mm input AC5mA~1000A

Product Features

PRODUCT OVERWIEW
A new type of current sensor developed by applying the principle of magnetic modulation. The primary current is compensated by the current generated by the internal oscillator to achieve the balance of the magnetic field. At this time, the secondary voltage can accurately reflect the primary current.
Product Features

Small current measurement performance is stable

Excellent accuracy, good linearity

Wide measuring range and strong overload capacity

Perforated structure, no insertion loss

Scope of Application

The signal system

Line detection

Leakage Monitoring System

Current difference measurement

Technical Parameter

Application examples

Example 1

Universal two isolation common ground output (one in, one out) is often used in this situation, where the power supply of the signal acquisition device is the same as that of the current transmitter, or the power supply of the current transmitter is directly provided by the signal acquisition device.


Example 2

The two-wire output (DC4~20mA) only requires 2 wires for output and power supply, which can save 1 wire compared to a general transmitter, reduce wire costs, and improve the reliability of the transmitter.

Example 3
220V power supply with three isolation (one in, one out) is often used in situations where there is no DC power supply on site or when 220V power supply is required.


Example 4
Dual output (one in, two out) is often used in situations where two different departments or locations require the same measured current signal. For example, if both the on-site control cabinet and the central control room need to collect current signals at the same time, one output can be sent to the control cabinet and the other can be sent to the central control room.
