Selection and Engineering Tools go. Dynavet Voltage Converters go. ATEX-certified for motors located in hazardous zones with Accessory kit S, also with very long motor cable length.
Direct forced air cooling, automatic temperature control To the top of the page. Customer benefits Cabinet units in IP21 or higher degrees of protection All of the drive units have their own connection space Compact dimensions Equipped with radio interference suppression Dynvaert harmonics fed back into the line supply, mainly on and pulse versions Almost unlimited motor cable lengths possible inherent to the system High overvoltage strength, e.
They can control both synchronous as well as induction motors. Possible with induction motors up to 1. Turn on more accessible mode.
Their equipping means that they can be easily used in all operating environments — even in hospitals and chemical plants. Safe, reliable and disturbance-free operation using the integrated filter, reactors and contactor s for the travel commands. Search Search term s Search. Output voltage basic fundamental: Depends on the motor Line supply frequency: Typical applications Elevators for passengers and loads, implemented as cable elevators according to DIN EN Inclined elevators To the top of the page.
Comfortable operation dynavegt — even without dynxvert feedback for asynchronous motors, up to approx. Speed feedback for induction motors: Quick and easy commissioning using optimum control adaptation and user-friendly, PC-supported software — IMS.
To dhnavert top of the page. Motor cable length shielded or non-shielded: Loheer regenerative operation, the rectifier on the line-side feeds the regenerated energy back into the line supply. Turn on more accessible mode. Two closed-loop control types for induction motors: As a consequence, the motor cable length is almost unlimited.
This is the reason that no additional wiring is required. Mechanical degree of protection: Search Search term s Search. Depending on the particular requirement, they can be flexibly used for supply voltages extending from V to V. Skip directly to content. Low Voltage Converters go. Technical data overview Rated input voltage Typ. Up to an elevator power of 30 kW the drive unit can be accommodated in a control cabinet with a depth of mm. Today, elevator drives are designed either as gearless or as geared solutions.
The power flows from the line supply to the motor for a motoring load. Selection and Engineering Tools go. Speed feedback for synchronous motors: They have a fully controlled B6 bridge circuit on the line side and a B6 inverter circuit on the output side, which utilizes the principle of interphase commutation; this distributes the DC link current from the DC link reactors with a square waveform with frequency f to the motor winding.
IP20 Ambient temperature, storage: Technical data overview Rated input voltage Typ. Dynavwrt and ready-to-connect unit with integrated EMC filter, dynavret reactor, braking chopper, braking resistor and a quiet contactor for the travel commands.
IP21, higher degrees of protection optionally available To the top of the page.
