Product Description
40KW Aluminum Power Resistors Aluminum Housed Wirewound High Power Resistors
►Product Strength
1. Aluminum crust surface with good performance in heat radiation, suitable for cooling plate
installation, can be used in an atrocious environment.
2. Small size, high power load.
3. High insulating capacity, encapsulation by non-flame inorganic Material, good performance in vibration.
4. Multi connection form will be easy to fix.
5. Widely used in Power supply, Transducer, Elevator, Arena audio, and high requirement equipment Industry.
6.Resistance tolerance: ±1%,±2%,±5%,±10%.
►Testing methods and performance
| Test items | Test methods | Requirements |
| Insulation voltage | imposed 2000vac on the house and core for one minute | No arcing and insulation breakdown phenomenon |
| solderability | >= 95% | 235+5℃, 2+0.5S |
| Terminal tensile strength | force 45N around the direction of the terminal vertically for 10s | no significant damage and mark clearly |
| Short time overload | Five times the rated power voltage imposed on the terminal for 5s | no mechanical damage |
| Vibration | Change the vibration from 10Hz to 55Hz then to 10Hz at 1m, three mutually perpendicular directions each for 2h, and the amplitude should be 1.5mm | no mechanical damage |
| Voltage life | the imposition of the rated voltage of the mains power supply 1000h, 1.5h pass, while 0.5h off, lasted for 500h. | no significant damage and mark clearly |
| Temperature | tested the resistance under 20 ℃ as R1, then tested under 200℃ as R2. Then calculated according to the following formula a=(R) | ±260ppm/℃ |
| steady damp-heat | put it into a 40℃+-2℃, incubator with 90%-95% moisture and maintained for 30-50 minutes | no significant damage and mark clearly, insulation resistance shall be more than 1GΩ |
