Current measurement gives faster response than temperature measurement. • Switching Power Supplies and kV kV kV Electronic Ballasts: True RMS sensing is the most accurate way to measure power supply or ballast input power. 041029/3 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.
