Notes : 1) The Max. Peak AC Current is the highest peak level of the primary signal that is taken into account for accurate True RMS calculation. Yet the device is designed for maximum continuous True RMS value equal to IPN, whereas the output is limited by the above specified output limitation.

2) According to the UL 508 Standard for Safety for Industrial Control Equipment the primary current must not exceed 475 A.t.RMS through the transducer hole.

Features

●● VFD and SCR waveforms current measurement

●● True RMS output

 

●● 4-20 mA current output ●● Panel mounting

 

●● Eliminates insertion loss

 

●● Isolated plastic case recognized according to UL94-V0

 

Advantages

 

●● Large aperture for cable up to Ø32mm

●● High isolation between primary and secondary circuits

●● Easy installation

 

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.

 

Application domain

 

●● Energy and Automation
