LEM DHR600C5 Ac/dc current transducer Datasheet

AC/DC Current transducer DHR-C5
IPN = 100..1000 A
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 0-5V
voltage output.

* The Max. Peak AC Current is the highest peak level of the primary signal that is
taken into account for accurate True RMS calculation. Yet the device is designed for
maximum continuous True RMS value equal to I PN, whereas the output is limited by
the above specified output limitation.
Applications
• VFD Controlled Loads
VFD output indicates how the motor
and attached load are operating.
• SCR Controlled Loads
Acurate measurement of phase
angle fired or burst fired (time
proportioned) SCRs. Current
measurement gives faster
response than temperature
measurement.
• Switching Power Supplies and
Electronic Ballasts
True RMS sensing is the most
accurate way to measure power
supply or ballast input power.
Application domain
• Energy and Automation

Safety
This transducer must be used in electric/electronic equipment with respect to
applicable standards and safety requirements in accordance with the
manufacturer’s operating instructions.
Installation and maintenance should be done with main power supply
disconnected.
The operator must have an accreditation to install this material.
Caution! Risk of electrical shock
When operating the transducer, certain parts of the module can carry hazardous
voltage (e.g. primary conductor, power supply).
Ignoring this warning can lead to injury and/or cause serious damage.
The user must take care of all protection guarantee against electrical shock.
This transducer is a built-in device, whose conducting parts must be inaccessible
after installation. A protective housing or additional shield could be used.

• VOUT is positive when IP flows in the direction of the arrow.
• The return busbar and primary conductor elbow must be located
at least at 2.5 x window length more far away from the transducer
case.
• The temperature of the primary busbar can not exceed 90 °C.
• Dynamic performances are the best with a primary busbar
completely filling the primary aperture.
• This is a standard model. For different versions (supply voltages,
different outputs, bidirectional measurements...), please
contact us.
