QKTB9-100/250 Explosion proof driver controllerDetailed product description：

Scope of application and working conditions:

The QKTB9-100/250 explosion-proof driver controller for industrial and mining electric locomotives (old model QKT9-3/4B) is suitable for starting, speed regulation, forward, backward, and lighting of Hunan 8T battery electric locomotives and has short-circuit protection function.

This driver controller is suitable for the following working environments:
1. Altitude not exceeding 1200m;
2. The ambient temperature ranges from -20 ℃ to+40 ℃ (with a monthly average temperature of+25 ℃);
3. The relative humidity of the surrounding air does not exceed 95%;
4. In places where there is a mixture of methane and coal dust explosions;
5. No harmful gases capable of damaging insulation and corroding metals; Has an impact acceleration of no more than 30m/s2 relative to the longitudinal direction of the locomotive.
6. The amplitude A of the sinusoidal vibration with a step rate f of 2-50Hz relative to the vertical, longitudinal, and transverse directions of the locomotive is:

2≤f≤10Hz	A=25/f(mm)
10≤f≤50Hz	A=250/ftwo(mm)

7. Installed in the driver's control room of the battery type mining electric locomotive.
