Monitoring is effective when a connected load’s real current consumption is determined in as precise a manner as possible.
Thanks to the real effective value measurement (True RMS), our ACT20P-CMT and ACT20P-CML universal current measuring transducers record sine and distorted direct and alternating currents with excellent precision. An intelligent monitoring function means our ACT20P devices are able to accurately detect current overloads or shortfalls. This means you can counteract overloading consumers in good time. There is also the option of exact monitoring of total current. This means the failure of individual consumers or whole electric circuits can be reliably detected.
In combination with passive current transformers, the new ACT20P-CML current measuring transducers can also be used to measure very high AC currents. This way, the measurement range can be extended according to application needs. For both current measuring transducers, exceeding of the measurement range is indicated according to NAMUR NE 43 and NE 44.
ACT20P current measuring transducers allow you to simultaneously measure and monitor the currents of connected loads. This can reduce overloads, for example on motors or lifting or conveyor gear. Damage as a result of reduced performance, for cooling fans, light and heating circuits or photovoltaic trains, for example, occurs less often.
High level of accuracy – reliable protection
ACT20P current measuring transducers are characterised by their high level of accuracy, amounting to at least 0.5 % of the measurement range, and indicate measurement range exceedance pursuant to NE43 and NE44. This translates into precise total load measurements, so you can reliably detect the failure of individual consumers too – even in faulty electricity grids.
Simple and quick configuration
DIP switches and potentiometers are located on the front, which means they’re quickly accessible even when installed.
Easy to install
The asymmetrical cable bushing of ACT20P-CMT current measuring transducers makes it easier to feed through the power cable and permits precise measurement on an extremely small space.
Precise measured values
The real-value effective procedure allows you to record the connected load’s real power consumption, so you can reliably identify when levels exceed or fall below the nominal current.
Wide field of application
In combination with passive current transformers, the new ACT20P CML current measuring transducers can also be used for measuring very high AC currents.
High process reliability
Reliable function thanks to a galvanic four-way isolation and an impulse withstand voltage of 6.4 kV according to IEC 61010-2-201
