Characteristics of Aluminum Housed Resistors
1, Aluminum housed resistors are commonly used in power supplies, inverters, elevators, lifting, marine, servo, stage audio and CNC equipment and other high demand for electrical circuits, and can work for a long time in the harsh industrial control environment;
2, The metal shell of the aluminum housed resistors take high-grade aluminum alloy material cut from high-grade products; after plating solution, strong antioxidant capacity, elegant shape;
3, Aluminum housed resistor with high temperature, overload characteristics of strong, so that it does the double results of small size and high power, thus effectively saving device space;
4, A variety of wiring methods (small power to take the lead type, high power to take the conductive row or lead type), easy to install;
5, The adoption of flame retardant inorganic materials and aluminum shell integrated package, good shock resistance, good insulation, high peace of mind;
6, Metal aluminum shell appearance with heat sink groove, good heat dissipation performance, suitable for heat sink device;
7, The tolerance scale can be mastered between ± 1% ~ ± 10%;
The Function Of Aluminum Housed Resistor
Aluminum housed resistor is a kind of braking resistor, the important function in the circuit for shunt, current limiting, voltage dividing, bias, filtering and impedance matching.
1, Shunt and current limiting: Aluminum housed resistor and a device in parallel, can effectively shunt, thereby reducing the current on the device.
2, The function of voltage division: aluminum resistor and a device in series, can effectively divide the voltage, reduce the voltage on the device.
In practice, aluminum resistor can be used in series circuit for voltage divider to transform the output voltage, such as radio and amplifier volume control circuit, semiconductor tube work point bias circuits and voltage reduction circuits.
3, Charging or discharging
Aluminum housed resistors are also used with some components to form charging or discharging circuits to complete the charging or discharging consequences.
