[Application]
These units rectify AC power to DC and supply it to electromagnetic
Lifma. All electromagnetic Lifmas require a rectifier. Three models are
available; KR-P, A, RH-MW. Select them according to your purpose of
usage.
RH-MW 《Rectifier with reverse exciting
circuit》
(for holding release)
Workpieces with flat lifting surfaces, or made from material which tends
to retain residual magnetism, may not be easy to release when the power
supply is turned OFF. In these cases, a reverse current flow, is needed
to cancel the residual magnetism, and complete the release.
[Features]
The DC voltage can be varied in a range of 0 to 180V.
External control input terminals are provided.
An overvoltage protection function is incorporated.
Precautions for use
The rectifier KR Series and RH Series
use electronic PC boards and small relays inside the rectifiers and
therefore, are not suitable for use in applications subjected to
constant vibrations, such as on cranes, for example. Such use also
voides the warranty even if a failure occurs within the warranty
period.
For installation in places thar are subjected to constant vibrations,
anti vibration measures need to be taken. The external signal input
wires must be shielding wires and must be limited to 10 m long
maximum.
Operation procedures and technical specifications of other
manufactures lifting magnets should not be applied to our lifting
magnets or, any other makes.
