characteristics of relay-cabinet, type vka...
purpose
Cabinets of type vks are used as addition to the frequency inverter of type vkv... and are for direct wall mounting. Therefore smaller switchboxes can be used and there is no heat accumulation any more within the switchbox. The separation of frequency inverter and elevator control system leads to an easy transportation and easy mounting.
general
- Modular construction; the frequency inverter is put on the relay-cabinet. Easy to mount and easy to service.
- Meets the EMC requirements and provides easy connecting
- Mounting bars for easy wall-mounting
- PG-Verschraubung mit Schirmaufnahme, Zugentlastung
- Easy connection: mains - frequency inverter - motor
- Enclosure: frequency inverter: IP20; brake resistor (mounted): IP20
specification
- Input choke to meet the requirements of the local power distributors
- Two power-contactors (230V AC, optional 110V AC) with spare contacts
