your reliable partner Spark Quenching Unit Type 070.000.6 Application Reduces spark production on the switching contacts occurring during DC-side switch-off of inductive loads. • Voltage limitation according to VDE 0580 2000-07, Item 4.6. • Reduction of EMC-disturbance by voltage rise limitation, suppression of switching sparks. • Reduction of brake engagement times by a factor of 2 - 4 compared to freewheeling diodes. Function The spark quenching unit will absorb voltage peaks resulting from inductive load switching, which can cause damage to insulation and contacts. It limits these to 70 V...

your reliable partner Electrical Connection Magnetic Field Removal • DC-side Switching ROBA -switch The power circuit is interrupted in front of the rectifier. The magnetic field slowly reduces. This delays the rise in braking torque. When switching times are not important, please switch AC-side, as no protective measures are necessary for coil and switching contacts. When switching DC-side, high voltage peaks are produced in the coil, which can lead to wear on the contacts from sparks and to destruction of the insulation. The power circuit is interrupted between the rectifier and the coil as...

your reliable partner Contactless release monitoring for ROBA-stop® safety brakes • Wear-free • Robust • Magnetic field-resistant • Absolutely reliable Function Release monitoring prevents unpermitted operating conditions such as for example starting up against a closed brake. mayr® power transmission, international leaders in safety brakes for safety-critical applications such as for example passenger elevators or vertical axes, now provides a contactless system with inductive proximity switches for its safety brakes as an alternative to the tried and tested release monitoring system with microswitches....
