BE Models (For ordinary control)

These are basic models of power supplies for controlling electromagnetic clutches and brakes with rated voltage of 24 V DC. The 24 V DC required to operate electromagnetic clutches and brakes can be obtained simply by connecting/inputting either 100 V AC or 200 V AC specifications.Since they output full-wave rectified 24 V DC isolated and stepped down by a transformer, the power supply is sturdy, safe, and highly reliable. The construction is very simple, unitizing a transformer and rectifier in a compact form factor, and maintenance is easy.

Output type

Using a transformer to step-down the voltage and perform full-wave rectification on single-phase power from a commercial power supply produces a DC voltage output of 24 V DC. The output voltage may be affected by pulses as the signal is not smoothed, but these pulses should not have any effect on normal, daily operation of electromagnetic clutches and brakes. For applications requiring highly accurate clutch and brake responsiveness with no fluctuations in voltage whatsoever, use a power supply with a smoothed supply voltage or a Miki Pulley BEH model power supply

Power supply voltage fluctuations and output voltage

This power supply device experiences fluctuations in output voltage at the same rate as it experiences fluctuations in input voltage. Keep power supply voltage fluctuations to within a range of ±10% to maintain normal operation.
