6Normal Operational Conditions

In summer the ambient temperature is 45,humidity is 90%.In winter the ambient temperature is -20, humidity is 50%

7ventilation power and the control power of the load bank are 3 phase 5 wire ( 380V+N+PE).

8Cooling mode: forced air convection, the fanner with axial-flow, the direction of the air is coming from the bottom and outgoing from the above.

9Controlling mode: Manual control.

10Load bank rated power error: thermal state: ±4, cold state: ±2.

11Protection device: over-current, short-current, over-load protection for the fanner. With short circuit and over load protection for resistance pile.

12) The temperature for load bank outlet is about 250, temperature for enclosure is 5-10 higher then normally temperature, with partition for resistor and enclosure.

13) IP Degree for main loop IP20

14) Insulation degree for motor: F
