Danfoss Drives introduces three new models to its popular family of VLT 2800 Series drives.
Drives have DeviceNet option
Danfoss Drives has announced that DeviceNet is a new factory installed option available on all VLT 2800 Series drive models.
Both packages are UL and C-UL listed.
Both APU configurations include the VLT2800 Series drive installed in a NEMA 1 rated, all steel enclosure.
The keypad and display are accessible through an opening in the enclosure, so there is no need to open the enclosure to access either.
When provided, the disconnect switch interlocks with the APU enclosure for operator safety.
The Fuse and/or Disconnect package features a rotary disconnect switch that allows the input line to the drive to be disconnected, and/or fast-acting drive fuses designed to react quickly enough to protect the drive.
The Bypass package includes a two-contactor or three-contactor bypass used to electrically select whether the motor is driven by the drive, connected to the full-speed bypass, or disconnected from both.
Also included with the Bypass package are a door interlocked input disconnect switch or circuit breaker, fast-acting drive input fuses, Drive/Off/Bypass or Drive/Off/Bypass/Test switch with DRIVE and BYPASS pilot lights, and class 20 motor overload for motor protection when running in bypass.
Bypass options include 3% impedance input line reactor, automatic bypass, common run/stop, bypass undervoltage protection, and Hand/Off/Auto selector switch and manual speed potentiometer.
Danfoss Drives is a leading producer of precision mechanical and electrical components and intelligent "mechatronic" devices.
Danfoss created the VLT" name when they introduced the world's first mass-produced AFD in 1968, and the name has set the standard for quality drives ever since.
