IP20 Ambient temperature, storage: Skip directly to content. Line supply cos phi 1: Turn off more accessible mode. Turn off more accessible mode. Depending on the particular requirement, they can be flexibly used for supply voltages extending from V to V.

This means that from the inherent principle, 4-quadrant operation is possible without requiring any additional measures. Output voltage basic fundamental: Tools Drive Technology Drive Technology. This is the reason that no additional wiring is required.

LOHER DYNAVERT L PWM Inverters for Lifts

Tools Drive Technology Drive Technology. Speed feedback for synchronous motors: For regenerative operation, the rectifier on the line-side feeds the regenerated energy back into the line supply.

IP21, higher degrees of protection optionally available To the top of the page. Up to an elevator power of 30 kW the drive unit can be accommodated in a control dynavret with a depth of mm.

The power flows from the line supply to the motor for a motoring load.

dynwvert Compact and ready-to-connect unit with integrated EMC filter, line reactor, braking chopper, braking resistor and a quiet contactor for the travel commands. Two closed-loop control types for induction motors: Search Search term s Search. Mechanical degree of protection: ATEX-certified for motors located in hazardous zones with Accessory kit S, also with very long motor cable length. Medium Voltage Converters go. Search Search term s Search.

IP21, higher degrees of protection optionally available. They can control both synchronous as well as induction motors.

Comfortable operation possible — even without speed feedback for asynchronous motors, up to approx. As a consequence, the motor cable length is almost unlimited. Direct forced air cooling, automatic temperature control.

Technical data overview Rated input voltage Typ. Selection and Engineering Tools go. Low Voltage Converters go. Safe, reliable and disturbance-free operation using the integrated filter, reactors and contactor s for the travel commands. Quick and easy commissioning using optimum control adaptation and user-friendly, PC-supported software — IMS. Speed feedback for induction motors: Customer benefits Compact and ready-to-connect unit with integrated EMC filter, line reactor, braking chopper, braking resistor and a quiet contactor for the travel commands.

Selection and Engineering Tools go. Depends on the motor Line supply frequency: 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 dynavdrt interphase dynaverrt this distributes the DC link current from the DC link reactors with a square waveform with frequency f to the motor winding. Today, elevator drives are designed either as gearless or as geared solutions.
