Notes :
1)
The max. peak AC current is the highest peak level of the primary signal
that is taken into account for accurate True r.m.s. calculation.
Yet the device is designed for maximum continuous true r.m.s. value
equal to I
PN
, whereas the output is limited by the above specified output
limitation.

WARNING: The specified characteristics of the transducer are only
guaranteed if the paired top and bottom parts are mounted together and
not mixed with similar parts of other transducers.
AC/DC Current transducer AHR-B10
The transducer for the electronic measurement of DC & distorted AC
waveform currents, with galvanic isolation between the primary circuit
(power) and the secondary circuit (measurement).
True RMS 0-10 V voltage output.
I
PN
= 500 .. 2000 A
Features
•DC + distorted AC waveform currents
measurement
•True RMS output
•Busbar or panel mounting
•Split core type
•Isolated plastic case recognized
according to UL94-V0.
Advantages
•High isolation between primary and
secondary circuits
•Eliminates insertion loss
•Easy installation.
Applications
• AC power supplies or Motors:
True RMS current sensing - the most
accurate way to monitor power supply
or motor input power
• VFD Controlled Loads:
VFD output current monitoring to
indicate how the motor and the
attached load are operating
• SCRs or Switch-mode Rectifiers:
Accurate measurement of output
current
• Renewable Energy Installations or
Backup Batteries:
Continuous condition minitoring
allowing automatic failure detection/
anticipation.
Application domain
•Energy and Automation
