LEM APR400B10 Ac current transducer Datasheet

AC Current transducer APR-B10
IPN = 10 .. 400 A
Split core transducer for the electronic measurement distorted AC
waveforms current, with galvanic isolation between the primary (High
power) and the secondary circuits (Electronic circuit). Switch selectable
ranges and True RMS 0-5V and 0-10V switch selectable voltage output.

• True RMS output
• Split core type
• 5V & 10V switch selectable voltage
output
• DIN mounting & Panel mounting
• Eliminates insertion loss
• Switch selectable ranges
Advantages
• Large aperture for cable up to
Ø18mm
• High isolation between primary and
secondary circuits
• Easy to mount
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.

Notes : Installation and maintenance should be done with power supply disconnected.
The operator must have accrediation to install this material.
The users must take care of all protection gurantee against electrical shock.
