RX20 3500w 10ohm 100ohm 200ohm Ceramic Wirewound Braking Resistor Porcelain Tube Winding Resistor Load Resistor
Good heat dissipation performance: The optimized design of heat dissipation structure ensures the thermal stability under high power operation.
Environmental adaptability: heat resistance, corrosion resistance, adapt to the changing
industrial environment.
High cost performance: Combined with high performance and durability, reduce the overall
cost of use.
Test project | Test conditions | Performance |
Temperature coefficient | There sistance value is measured at room temperature and at room temperature +100℃ respectively and the resistance change rate of each degree is calculated. | ±350ppm/℃ |
Short time overload | Apply avoltage of 10 times the rated power or the maximum load voltage(take the smaller value). | △R≤± (2%+0.052) |
Resistance to welding heat | Immerse in a tin furnace at 350±10%℃ for 2-3 seconds. | △R≤± (1%+0.052) |
Weld ability | Immerse in a tin furnace at 260±5%℃ for 2-3 seconds. | Solder area covers over95% |
Temperature cycle | Leave at -55℃ for 30 minutes,then at +25℃ for 10-15 minutes, then at +275℃ for 30 minutes,and finally at +25℃ for 10-15 minutes,in a total of 5 cycles. | △R≤± (1%+0.052) |
Load life in humidity | Overload rated voltage or Max. working voltage(get the lower) for 1000 hours (1.5 hours on and half-hours off) at the 40±2℃ and 90~95°relative humidity. | △R≤± (5%+0.052) |
Load life in heat | At a temperature of 70±2℃, apply the rated voltage or maximum operating voltage (which ever is lower) for a total of 1000 hours (1.5 hours on,0.5 hours off). | △R≤± (5%+0.052) |
Noncombustibility | Add AC load at 5,10,and 16 times the rated power for 5 minutes respectively. | No obvious flames |
