AC/DC Current transducer AHR-B5
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 0-5 V voltage output.

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

Note :
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.
allowing automatic failure detection/
anticipation.
