AC/DC Current transducer AHR-B5

The transducer for the electronic measurement of DC & distorted AC

waveform currents, with galvanic isolation between the primary circuit

(power) and the secondary circuit (measurement).

True RMS 0-5 V voltage output.

I

Features

• DC + distorted AC waveform currents

measurement

• True RMS output

• Busbar or panel mounting

• Split core type

• Insulated plastic case recognized

according to UL94-V0.

Advantages

• High isolation between primary and

secondary circuits

• Eliminates insertion loss

• Easy installation.

Applications

• AC power supplies or Motors:

True RMS current sensing - the most

accurate way to monitor power supply

or motor input power

• VFD Controlled Loads:

VFD output current monitoring to

indicate how the motor and the

attached load are operating

• SCRs or Switch-mode Rectifiers:

Accurate measurement of output

current

• Renewable Energy Installations or

Backup Batteries:

Continuous condition minitoring

allowing automatic failure detection/

anticipation.

Application domain

• Energy and Automation
