The INTORQ spark suppressor protects the coil and contact against impermissibly high induced voltages with switching on the DC side.
It comprises a special induction-free pulse capacitor which immediately takes up the high-speed current peaks which occur during switching operations.
This considerably reduces the amount of sparking at the contact (contact erosion).
In the absence of a suppressor circuit, the spark, the induced voltage and the switch off time are all dependent on contact parting speed, air humidity, atmospheric pressure and other environmental factors.
In all cases, increased contact erosion and varying switch off times should be expected.
In the absence of a suppressor circuit, the induced voltage may exceed the values permitted by VDE 0580, which can lead to coil failures.

Bridge/half-wave rectifiers are used to supply power to the electromagnetic DC current spring-applied brakes approved for operation with this type of rectifier. Any other use is subject to the approval of INTORQ.
Once a set overexcitation time has elapsed, the bridge/halfwave rectifiers switch from bridge rectification to half-wave rectification. This makes it possible to improve switching performance or reduce power in accordance with load dimensioning. Terminals 3 and 4 are in the DC circuit of the brake. With switching on the DC side, integrated overvoltage protection at terminals 5 and 6 limits the induced voltage peak.
Transformer switch TS 48 contains the entire current supply for a 24 V DC coil with transformer, rectifier and switching transistor with suppressor circuit.
The transistor is used for switching; there is no contact erosion.
The high induced voltage enables the switch off times indicated in the catalogue for switching on the DC side to be achieved.
The EDS 48 electronic dual switch contains the complete current supply for a 24 V DC voltage coil and can be operated using control voltages (e.g. from a PLC) or pulses.
A pulse at the START input will engage the clutch until a pulse at the STOP input disengages the clutch and applies the brake.
A program switch can be used to preselect the type of brake to be controlled (electromagnetic or springoperated brake).
SEGC High-Speed Switchgear
INTORQ SEGC high-speed switchgear are used for highspeed coil excitation at a rated voltage of 24 - 215 V.
The operating voltage can be set to the desired values using appropriate MP capacitors (must be ordered separately).
Since the devices are a constant source of current, the same current flows regardless of whether the coil is cold or warm; i.e., the torque is largely independent of the coil temperature.
Mechatronic Brake System
Spring-applied brakes are used as modular components in electrical drives to decelerate or bring masses to a defined stop - even in the event of the loss of the power supply. Spring applied brakes are generally used as "on or off brakes", whereby the availability of the power supply determines the activation and deactivation of the braking torque.
However, it is often necessary to decelerate the drive with variable braking torque. This option is supported by the mechatronic brake system, which comprises a standard INTORQ BFK458 spring-applied brake and the INTORQ Control electronic control unit. The mechatronic brake system makes it possible to set the braking torque of spring-applied brakes precisely with an "electronic brake pedal".
