Adjustable Power Resistor

Adjustable power resistors are an important component in the world of electrical and electronic engineering. They provide a range of functions and can be found in a variety of applications from medical equipment to sound systems. This article outlines the application field and working principle of the D12K15R Adjustable Power Resistor.The D12K15R adjustable power resistor is a thermally-controlled loaded resistor that is used to design and manufacture controlled switching of circuits. It is a two-termination device, meaning it has two connecting pins, for connecting it to a circuit. The resistor is constructed from a combination of an intermittent resistor and an ON/OFF relay. When the ON/OFF relay switches, the resistor changes the impedance on the connected circuit and vice versa. When the current is switched off, the resistor returns to its initial resistance.The D12K15R adjustable power resistor is mainly used in industrial or commercial systems such as HVAC, automotive, medical, and lighting systems. It is designed for flexible, cost-effective current and voltage control. The D12K15R adjustable power resistor can be used in any application where an adjustable load is required, including switching power supplies, motor and lighting control, and voltage stabilization circuitry. The resistor can be used to reduce noise and ripple in power transmission lines, to reduce power consumption in appliances, and to provide overload protection against excessive current flow.The D12K15R works on the principle of thermal control. A thermal control element is placed between the resistor and the control circuit. When the control circuit is switched on, it applies a current to the thermal control element, heating the element. This in turn reduces the resistance of the resistor, which then allows current to flow through the circuit. When the control circuit is switched off, the thermal control element cools down and the resistance is restored to its initial value.The D12K 15R adjustable power resistor has a wide range of features and benefits. It can achieve an accuracy of 8% in its current and voltage control, which is significantly better than some of its competitors. It has an adjustable thermal shutdown temperature which can be set to overheat protection. It has a stainless steel body with a robust construction, so it is protected against corrosion and can withstand extreme temperatures. Additionally, its simple design makes it easy to use and install.In conclusion, the D12K15R adjustable power resistor is an ideal solution for applications where cost-effective, reliable current and/or voltage control is required. Its wide range of features and benefits makes it a great choice for industrial and commercial applications, providing accurate control and overload protection at an affordable price.
