ELDRO® DC devices are used in systems with an existing direct current power supply. The devices must be connected electrically in parallel to the motors. 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 devices are installed in the brake as an additional brake thruster. These devices 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.
➤ High operational reliability
➤ Long service life thanks to wear-free operation with permanent self-lubrication
➤ Soft and impact-free operation as a systemic result of the hydraulic operating principle
➤ Short regulating times
➤ Approved continuous operation S1
➤ High switching frequency of up to 2000 cycles per hour in switching mode S3
➤ Reversing operation without any restrictions
➤ Easy installation and removal
➤ Arbitrary direction of motor rotation, therefore no changeover contactors required
➤ Overloading is not possible during Operation
➤ Arbitrary external limitation of the stroke path
➤ Stepless extension of the lifting and/or lowering times through the installation of valves
➤ The fill level of the operating medium is optimised according to the operating conditions and requires no further inspection.
