! ! WARNING !!
(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 working near high-voltage potentials. It
is recommended not to install the Flexible Transducer around a live bus that is at a
high-voltage potential. If installation is not possible when the bus is disconnected from
main supply, use appropriate gloves and/or equipment that are approved for working
around high-voltage potentials when installing the Flexible Transducer in the vicinity of
these hazardous potentials.
INTRODUCTION
The AMPROBE Flexible AC Current Transducer Model ACF-3000 SR is an assembly
similar in purpose to a CT or current transformer. It may be used to measure AC
currents from a low as a few 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 wave form in the conductor. The output signal is available via a 2 pin snap
connector.
ACF-3000 SR ELECTRONICS PACKAGE
The ACF-3000SR electronics package is permanently connected to the transducer.
When the ACF-3000 SR is turned on, the LED mounted behind the front label blinks
once, then goes out to minimize drain on the battery. When the batteries are nearing
the end of their life the LED flashes approximately twice per second, the batteries
should be replaced and as soon as possible. If the LED fails to flash once when the
unit is turned on, the batteries are dead, replace immediately.
The ACF-3000 SR comes equipped with an external mini jack located on the package.
This is for those wanting to supply power to the ACF-3000 SR for a longer period than
the internal battery life will allow. An external DC power supply is available for this
purpose but is sold as an option. The power required is +3.0VDC/10mA.
