[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.
