Over excitation voltage = 2 x nominal operating voltage, divided t
pick up
by two.
Standard 104 VDC, from stock available
All brakes are suitable for frequent start/stop.
The brake opening and closing response times can vary substantially depending
on:
• the type and viscosity of the oil
• the level of oil in the drum motor
• the ambient temperature
• the internal motor working temperature
Brake rectifier for i- and S-series
Using a fast acting rectifier or a phase rectifier will save energy because the
holding voltage is lower than the starting voltage.
AC switching (Terminals 1 and 2 of the
brake rectifier)
slow opening response time
brake voltage approx. 1 V
slow closing response time
DC switching (Terminals 3 and 4 of the
brake rectifier)
fast opening response time
brake voltage approx. 500 V
fast closing response time
Electronic rectifier behavior similary to DC-switching
Note
The usable brake torque is approximately 35% of the above listed torque
according to experience.
