Application information
●● HOxx-S series is designed to use a bus-bar or a cable 2) to carry the current through out the aperture with a maximum
capacity of 15 x 8 mm
●● Use of naked conductor is not recommended for panel mounting horizontal or vertical, insulation distance might not be
respected between busbar and fixation screw head.
Insulation distance (nominal values):
dCp
Between primary busbar and secondary pin
dCI
14.6 mm
-
Between primary busbar and core
-
11.34 mm
Between core and secondary terminal
-
1.18 mm
Notes: 1) For dedicated settings, minimum quantities apply, please contact your local LEM support.
2)
The maximum magnetic offset referred to primary is inversely proportional to the number of turns, thus is divided by 2 with 2 turns

HO 50 .. 250-S series
Definition of typical, minimum and maximum values
Minimum and maximum values for specified limiting and safety conditions have to be understood as such as well as values
shown in “typical” graphs.
On the other hand, measured values are part of a statistical distribution that can be specified by an interval with upper and lower
limits and a probability for measured values to lie within this interval.
Unless otherwise stated (e.g. “100 % tested”), the LEM definition for such intervals designated with “min” and “max” is that the
probability for values of samples to lie in this interval is 99.73 %.
For a normal (Gaussian) distribution, this corresponds to an interval between -3 sigma and +3 sigma. If “typical” values are not
obviously mean or average values, those values are defined to delimit intervals with a probability of 68.27 %, corresponding to
an interval between -sigma and +sigma for a normal distribution.
Typical, maximal and minimal values are determined during the initial characterization of a product.
Remark
Installation of the transducer must be done unless otherwise specified 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
Safety
This transducer must be used in limited-energy secondary circuits according to IEC 61010-1.
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.
Caution, risk of electrical shock.
When operating the transducer, certain parts of the module can carry hazardous voltage (e.g. primary bus bar, power supply).
Ignoring this warning can lead to injury and/or cause serious damage.
This transducer is a build-in device, whose conducting parts must be inaccessible after installation.
A protective housing or additional shield could be used.
Main supply must be able to be disconnected.
