SMVector frequency inverter NEMA 4X (IP65)

Lenze – AC Tech’s most technically advanced inverter drive continues it’s tradition of innovative compact inverter design. The performance and flexibility make the SMVector an attractive solution for a broad range of AC Motor applications and with several communications protocols available, networking drives and components into a system solution can be done now or in the future.

The SMVector NEMA 4X (IP65) is available in two enclosure materials – for indoor only use and for indoor/outdoor use. These rugged enclosure options are ideal for many industries including food / beverage, waste water, chemical metering and processing, and pharmaceuticals.

The power ranges of the SMVector in NEMA 4X include:

  • 120/240V 1Phase Input, up to 1.5 HP (1.1kW)
  • 200/240V 1 or 3 Phase Input, up to 3.0 HP (2.2 kW)
  • 200/240V 3 Phase Input, up to 30 HP (22 kW)
  • 400/480V 3 Phase Input, up to 30 HP (22 kW)
  • 480/600V 3 Phase Input, up to 30 HP (22 kW)

The SMVector Series can be used with 3-phase AC induction motors and is available in NEMA 1 (IP31) , NEMA 4X (IP65) and NEMA 4X (IP65) with an integral disconnect switch. Filtered input versions of the SMV are available in NEMA 4X (IP65) models for compliance with the CE EMC directive.

Programmable digital and analog I/O allow the drive to be configured for many application specific tasks such as multiple preset speeds, electronic braking and motor jogging to name a few. Like all Lenze – AC Tech sub-micro drives, the SMVector uses EPM Memory technology for fast and efficient programming.

Technical documentation for the SMVector Series Drive, and all AC Tech brand drives, is available in our Technical Library.

type 4X (IP65) enclosures are available for either indoor use, suitable for most indoor industrial environments; or indoor/outdoor use that offers UV protection and has higher impact strength at low temperatures.
