Resistive Load bank

The resistive load bank is a kind of test electronic load equipmnent for the generator, the UPS (UPS), power equipment and so on

LGFZ Load Bank Specification

Main parameters and fitting

1) Resistance load equipment: 15~10000KW

2) Power factor: 0.8~1.0

3) Test voltage: three phase AC voltage 400V

4) Frequency: 50--60Hz

5) Active power step:

We can meet client's need.

6) Normal Operational Conditions

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

7) ventilation power and the control power of the load bank are 3 phase 5 wire ( 380V + N + PE), total control power is 1 KW.

8) Cooling mode: forced air convection, the fanner with axial-flow: the direction of the air is coming and outgoing from the side, the control box is beside the wind input end(refer to the show drawing).

9) Controlling mode: computer control.

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

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

12) The temperature for load bank outlet is about 250

13) IP Class for main return circuit: IP23

14) Insulation degree for motor: F

15) Working mode: continuous

16) Weight: 50KG~20000KG

17) overall dimension: L900 X W1200 X H1000~Container

We use computer key to operate, you just input the needed active power and the computer can calculate and operate the result then input the load by itself. You can increase the short time load. The load bank also can serve and print the test parameters.

 The parameters the computer will show:

1) Three phase voltage, three phase current, three phase power, total power, three phase reactive power, total reactive power, three phase power factor, total power factor, haemonic.

4) Impact test: 12 second impact time: catch the transient voltage, the frequency max value, the current min-value and recover time, can calculate the impact transient voltage deviation, the transient state frequency difference;

5) Unload suddenly test: 12 seconds unload time suddenly: May catch the transient voltage, the frequency maximum value, the current minimum value and recover time, can calculate unload the transient voltage deviation, the transient state frequency difference suddenly;

6) Records the wave: can carry on 1 second voltage to record the wave, each profile 128 spots.

Technical service:

1) Electrical schematic diagram, connecting diagram, layout chart, structure maintenance drawing.

2) Operation and maintenance specification

3) Before the equipment first use, Our company sends engineer to provide one day technical service for free.

Equipment approval:

The equipment Harmonic carries on Lingo , the equipment gets up transports the preceding week, Our company informs your firm to go to Our company to carry on one day-long equipment approval (and has training, according to equipment manufacture inspection standard and technical agreement approval). After the equipment approval finished, needed the bilateral signature to become effective.

Quality Insurance:

We are responsible to change or maintain the equipment under the warranty, if there is something wrong caused for the manufacturing defect or manufacturing equipment damage. But not include the damage caused by your negligence.
