VX2 System
Part Number
- A801225 (VX2 VFD Module – Liquid Cooled VFD 525HP)
- A801226 (VX2 VFD Module – Liquid Cooled VFD Dual 200HP)
- A801227 (VX2 DC Rectifier)
Description
This 1140V AC Variable Frequency Drive system is available as liquid or air-cooled VFD modules designed for various mining applications, including highwall miners. Modules can be connected to extend flexibility.
Features
- Speed can be controlled manually, remotely or automatically using internal or external controls.
- Rate of acceleration and deceleration is controlled allowing a perfect soft start or soft stop.
- Controlled soft starts reduce the mechanical stress on the motor shaft and load.
- Reduced starting current and improved power factor lessens demand on the electrical infrastructure and can reduce the size of standby generators.
- Flexible design:
- Four axis mounting orientation
- Ease of remote monitoring / control
- Over-voltage / under-voltage protection
- PID control, signal follower control
- Separation of high and low voltage
- Quick disconnect I/O terminals
- O/L, GF and over current protection
- Torque control, load sharing control
