BEW (W) Models

These are compact, high-capacity, widely compatible power supplies that can be used in the full range of electromagnetic clutches and brakes of rated voltage of 45 V DC/90 V DC/180 V DC.The direct current required to operate electromagnetic clutches and brakes can be obtained simply by connecting/inputting using 100 V AC, 200 V AC, or 400 V AC specifications. Since they can handle half-wave/full-wave rectified output by switching the connection method, electromagnetic clutches and brakes of various specifications can be handled by these power supplies alone.

[Characteristics]

For Both Half-wave Rectified and Full-wave Rectified

For BEW-4W types, you can select between half-wave rectified and fullwave rectified by changing the connections of the wiring as shown in the figure at right.
These power supply devices are high Wattage and allow a wide range of voltage inputs, from low voltage to high. As a result, a wide variety of electromagnetic clutches and brakes can be handled by a single BEW-4W power supply alone. You can either focus on the type of brake, assuming you will rewire, or conversely, handle a variety of types of brakes with a BEW-4W power supply alone.
[How to Calculate Output Voltage] Output voltage = Input voltage × a (a set coefficient) * a (set coefficient) = 0.45: half-wave rectified/0.9: full-wave rectified (Ex.)
Half-wave: AC200V × 0.45 = DC90V
Full-wave: AC100V × 0.9 = DC90V
Note that when the rated voltage of the electromagnetic coil does not match the output voltage calculated above, you will not be able to obtain the electromagnetic clutch/brake characteristics given in the specifications.
