PRODUCT FEATURES
2.1 Description
The MiniFlex
®
HF is a compact flexible AC current transformer composed
of a flexible sensor and an electronic module. It is designed to measure
from 5Hz to 1MHz. The flexible sensor permits measurements on conduc
-
tors where standard clamp-on probes could not be used. In particular, it
can be installed in confined spaces, places where access is difficult, or
even wrapped around irregular shapes.
The MiniFlex
®
HF is lightweight. It does not use magnetic cores like stan
-
dard transformers. The transformation principle is based on an air core.
It presents virtually no load to the system under test, has a low phase
shift and excellent frequency response from 5Hz to 1MHz at -3db, and
cannot be damaged by overloads. The sensor assembly is insulated for
1000V CAT III; 600V CAT IV. The MiniFlex
®
HF meets EN 61010 and is
CE marked.
The MiniFlex
®
HF has an mV output proportional to the current measured
for direct readings on oscilloscopes, DMMs, data loggers and power or
harmonic meters. TRMS measurements are taken when connected to a
TRMS meter. The MiniFlex
®
HF is insensitive to DC currents and only the
AC component of the measured signal is measured.
The flexible sensor is available in lengths of 6" and 10".
