QKT45-100/250 Mining General Driver Controller

Scope of application and working conditions:

The QKT45-100/250 mining general type driver controller (old model QKT45-3) is used for 5T/7T overhead resistance speed regulation locomotives, as a starting speed regulation, stopping, and reversing function.
This driver controller is suitable for the following working environments:

1. Altitude not exceeding 1200M (to be negotiated with the user if exceeded).
2. The ambient temperature is -20 ℃ -+40 ℃ (when the monthly average temperature is+25 ℃).
3. The relative humidity of the surrounding air should not exceed 90%.
4. A place without combustible gas and coal dust explosion mixture.
5. There are no harmful gases that can damage insulation and corrode metals.
6. On devices with rain, snow, and splash protection.
7. When tilted within 10 degrees relative to the normal position
8. Has an impact acceleration of no more than 30m/s2 relative to the longitudinal direction of the locomotive.
9. A sinusoidal vibration with a frequency f of 2-50HZ relative to the longitudinal, transverse, and vertical directions of the locomotive, with an amplitude A not greater than:
2≤f≤10HZ A=25/f（mm）
10≤f≤50HZ A=250/f2(mm)
10. Installed in the driver's control room of XK5T or XK7T battery type mining electric locomotive.
