BE Model (for general control)

This is the basic model of a power supply unit for controlling electromagnetic clutches and brakes rated at 24 V DC. Simply connect it to either a 100 V AC or 200 V AC power source to obtain the 24 V DC required to operate electromagnetic clutches and brakes.It uses a transformer to provide isolation and step down the voltage, outputting a full-wave rectified DC 24V.

[Characteristics]

Output Method

Single-phase AC is stepped down and full-wave rectified to provide DC24V output. Though the unsmoothed output contains ripple, it causes no issues in normal clutch/brake operation. For minimum response variation, use a smoothed supply or the BEH Model.

Power Supply Voltage Fluctuations and Output Voltage

The output voltage of this power supply fluctuates in direct proportion to fluctuations in the input voltage. To ensure proper operation, please keep fluctuations in the supply voltage within a range of ±10%.
