RECTIFIER FOR ELECTROMAGNETIC LIFMA™ [Model RH-MW / KR-A / KR-P]

RH-MW205B

KR-P203
KR-P203

[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.
