Advantages

· Large aperture for cable up to Ø18mm

· High isolation between primary and

secondary circuits

· 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.
