## **Features** 

- VFD and SCR waveforms current measurement 

- True RMS output 

- 4-20mA current output 

- Panel mounting 

- Eliminates insertion loss 

## **Advantages** 

- Large aperture for cable up to Ø32mm 

- High isolation between primary and secondary circuits 

- Easy to mount 

## **Applications** 

- VFD Controlled Loads: 

   - VFD output indicates how the motor and attached load are operating. 

- SCR Controlled Loads: Acurate measurement of phase angle fired or burst fired (time proportioned) 

SCRs. Current measurement gives faster response than temperature measurement. 

- Switching Power Supplies and Electronic Ballasts: True RMS sensing is the most accurate way to measure power supply or ballast input power. 

Notes : Installation and maintenance should be done with power supply disconnected. The operator must have accrediation to install this material. The users must take care of all protection gurantee against electrical shock.

When operating the transducer, certain parts of the module can carry hazardous voltage (eg. primary busbar, power supply). Ignoring this warning can lead to injury and/or cause serious damage. 

This transducer is a built-in device, whose conducting parts must be inaccessible after installation. 

A protective housing or additional shield could be used. Main supply must be able to be disconnected.
