Implemented loads to Power Supplies in three ranges 50%, 75% and 100%:
The available power supply tester can support the different load types shown in the table below. These loads have different values of power, voltage, and current used for different switching power supplies. These resistors are capable of withstanding temperatures up to 500 ° C.
The resistance of the coil is made of insulation core or rod, which is obtained by rotating the wire around the insulation resistance. The resistive wire is usually tungsten, manganese, nickel or chromium nickel alloy and the core is made of porcelain, basil, continuous bond paper or ceramic deposited materials.
