Current Transducers

The ACS770ECB-200U-PFF-T is a product of Allegro Microsystems Inc., a leading manufacturer in the field of current transducers. It is a single-channel, split core current transducer specifically designed to measure AC current. It is ideal for measuring both single and multiphase systems.

A current transducer is a device that can measure the electric current in a system, either directly or indirectly. There are two main types of current transducers – electrical and magnetic. Electrical current transducers, such as the ACS770ECB-200U-PFF-T, measure the current directly by sensing the voltage drop that occurs across a known impedance. Magnetic current transducers, on the other hand, measure the current indirectly by measuring the magnetic field produced by the current.

The ACS770ECB-200U-PFF-T is designed to measure alternating current (AC) up to a maximum of 200A. It features a split-core design that enables the transducer to split into two halves to be placed around an existing cable or conductor. This allows for easy installation without the need to disconnect the current carrying conductor. The device also features a small footprint, making it ideal for space-constrained applications.

The transducer works by converting the measured AC current into an AC voltage with a known ratio. This output voltage is then amplified by one or more amplifiers to create an output signal that is proportional to the measured current. The output signal can be used to measure the current in a system, as well as to monitor and control its operation.

The ACS770ECB-200U-PFF-T is designed to operate in a wide range of environmental conditions, from −40 °C to 125 °C. It also has a wide operating supply voltage range of 3.3 to 5.5 V. This makes it suitable for various applications, including motor drive applications and home and building automation systems.

The ACS770ECB-200U-PFF-T is a reliable and robust current transducer that is ideal for measuring AC currents in applications that require high accuracy and accuracy over a wide range of conditions. It is easy to install, requires minimal maintenance, and is suitable for a variety of applications.
