Q20A Brand New Split Core Clip On Clamp On Current Transformer with mA Output Class 0.1
Split Core Clip On Current Sensor Q20A-2 designed and manufactured
by GFUVE meets the latest safety and performance standards which
can measuring AC currents up to 200A. Current Sensor Q20A-2 allows
any clamp meter or multimeter to enclose a thick conductor within
20mm.
Clamp on current transformers are used for long term energy studies
which includes electric power quality monitoring device. It is
ideal for power and energy measurement.
A common form of current clamp comprises a split ring made of
ferrite or soft iron. A wire coil is wound round one or both
halves, forming one winding of a current transformer. The conductor
it is clamped around forms the other winding. Like any transformer
this type works only with AC or pulse waveforms, with some examples
extending into the megahertz range.
GFUVE Clamp-on Current Transformer are designed for fast and easy
installation.Clamp-on Current Transformer uses Permalloy magnetic
core or Silicon and amorphous core, with characteristics of small
size, high precision, good stability and strong anti-interference
ability.

FAQ, following questions will help you to select the matched probe
for your applications.
1. Please determine if you are measuring AC or DC?
GFUVE Q20A-2 is for AC measuring. If DC, we have hall effect models
to suggest.
2. What is the maximum current you will measure?
Current Sensor Q20A-2 maximum current is 240A.
3. What size conductor will you clamp onto? This parameter
determines the probe jaw size needed.
Q20A-2 can clamp conductor is φ20mm
4. What type of probe output do you need or can you work with (mA,
mV, A, AC, etc.)?
Q20A-2 Current Sensor can customize output with mA.
5. What is the working voltage of the conductor to be measured?
GFUVE probes should be used below 600 volts
6. What type of termination do you need: jacks, leads or BNC?
Q20A-2 standard has 2.5meter leads. We can offer jacks or BNC… as
options.
