• VFD Controlled Loads:

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

• SCR Controlled Loads:

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.
