Introduction

The current sensor is a sensor to measure the current as its name. However, The current is various. There is a current value up to 10κ amperes treated in the power plant from 1mA, and the shape of current waves also has AC, DC, and AC + DC. Since a method and a structure the best in each measuring object are different, there are also various current sensors. Tamura supplies the sensor using the Hall - Effect system for measuring the current value from several amperes to several kilo - ampere. The Hall - Effect current sensor measures the magnetic flux produced in proportion to the primary current without any direct contact with the primary circuit; the combination of the Hall element and magnetic circuit provide excellent solution for measuring AC/ DC current with galvanic isolation and zero insertion loss. The induced Vh is small and is amplified by an amplification circuit.

Features

• Measurement of DC, AC (kHz range), & complex current <AC + DC>
• The lineup of rated currents ranges from a few A to over 1000 A
• Galvanic isolation with many UL compliant configurations
• Fast response time
• High Reliability

Applications

• Current control and detection of over - current in various types of inverters. Used for general - purpose inverter, various types of power conversion equipment to control and to detect over - current. Also used to measure DC current from the battery.
• Various types of inverters (CVCF, vector), Industrial robots, automation, devices, NC
• UPS, Elevator, Laser Cutting Machines, Welding Machines, Various types of Regulated Power Supply
