ELDRO® DC thrusters are used in systems with an existing direct current power supply. The thrusters must be connected electrically in parallel. An electrical connection of the ELDRO® motors in series is not possible.
The ELDRO® DC series is also used to open brakes in the event of a voltage breakdown of the three-phase supply. In this case, these thrusters are installed in the brake as an additional brake thruster. These thrusters can then be supplied with a direct current voltage, for example, from a battery. This, for example, enables loads in the lifting unit to be lowered and set down safely.
