Characteristics
Output type
Two systems are available, half-wave rectified and full-wave rectified. Half-wave rectified takes a commercial power supply as the input and generates a halfwave rectified DC voltage on the output side. These power supply devices are known for their very simple construction and low cost, but their voltage pulse is large. They are therefore prone to generating variations in operating response in electromagnetic clutches and brakes, they produce a howling noise when conducting, and they tend to generate more heat from their electromagnetic coils than full-wave rectified supplies or smoothing supplies.
When the above are to be avoided, consider changing to a full-wave rectified supply, smoothing supply, or a DC 24 V specification.
Full-wave rectified power supply devices are known for having smaller voltage pulses than half-wave rectified supplies and tending to have little variation in electromagnetic clutch and brake operating response. They can thus be used not just for spring-actuated brakes but also for electromagnetic-actuated clutches and brakes.
Note that when the rated voltage of the electromagnetic coil does not match the voltage output from the power supply device, you will not be able to obtain the electromagnetic clutch/brake characteristics given in the specifications.
