PAC Series
AC/DC current clamp
DESCRIPTION
The PAC25 model accurately measures AC or DC currents by making use of the Hall effect
principle. This clamp with mV output is equipped with an automatic DC zero system and a
deactivatable Auto Power Off (APO) function. It can be powered by a standard mains power
pack via a Micro USB connector.
