15June2015/version 16 LEM reserves the right to carry out modications on its transducers, in order to improve them, without prior notice www.lem.com
Dimensions LA 55-P (in mm)
Mechanical characteristics
● General tolerance ±0.2 mm
● Primary through-hole 12.7 × 7 mm
● Fastening & connection of secondary 3 pins
0.6 × 0.7 mm
● Recommended PCB hole ⌀ 1.2 mm
Remarks
● I
S
is positive when I
P
ows in the direction of the arrow.
● Temperature of the primary conductor should not exceed
90 °C.
● Installation of the transducer must be done unless
otherwise specied on the datasheet, according to LEM
Transducer Generic Mounting Rules. Please refer to
LEM document N°ANE120504 available on our Web site:
Products/Product Documentation.
● Dynamic performances (di/dt and response time) are best
with a single bar completely lling the primary hole.
● In order to achieve the best magnetic coupling, the
primary windings have to be wound over the top edge of
the device.
● This is a standard model. For different versions (supply
voltages, turns ratios, unidirectional measurements...),
please contact us.
