Application
Reduces spark production on the switching contacts occurring
during VDC inductive load switching.
• Voltage limitation according to VDE0580 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 free-wheeling 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 70V and reduces the contact load.
Switching products with a contact opening distance of > 3 mm are
suitable for this purpose.
