The AMPROBE Flexible AC Current Transducer Model A C F - 3 0 0 0 D M - A is an
assembly similar in purpose to a CTor current transformer. It may be used to
measure AC currents from as low as several amps to a maximum of 3.0kA
rms. The device output is an analog voltage that is proportional to the current
in the conductor. The output signal is isolated from the hazardous conductor
potential and is an exact replica of the AC current waveform in the conductor.
The output signal is available via a 2 pin snap connector.
A C F - 3 0 0 0 D M - A ELECTRONICS PA C K A G E
The A C F - 3 0 0 0 D M - A electronics package is permanently connected to the
transducer and comes standard with two ranges selectable by the switch
mounted on the side of the electronics package. The ranges are 300A a n d
3 . 0 k A yielding respectively 300A and 3.0kA rms AC as the maximum current
that can be measured. When one of the ranges is selected, the unit is auto-
matically turned on.
N o t e : The 3.0kArange should only be selected if the measured current
is over 300A.

( Do not use until you have read this! )
High-voltage potentials may exist in the vicinity of the desired current
measurements. Use locally approved safety procedures when work-
ing near high-voltage potentials. It is recommended not to install the
Flexible Transducer around a live bus that is at a high-voltage poten-
tial. If installation is not possible when the bus is disconnected from
main supply, use appropriate gloves and/or equipment that are ap-
proved for working around high-voltage potentials when installing the
Flexible Transducer in the vicinity of these hazardous potentials.
