Panel indicators, pilot lights and other devices are important components of any electrical system. The QS103XXHG220 is one of these components, and is used to indicate a power source, an open circuit, or a fault in a circuit. This article will discuss the application field and working principle of the QS103XXHG220.

The QS103XXHG220 is a DC-rated indicator used in control panels and other industrial equipment. It features a bullet-proof body of galvanized steel and a plastic cap to protect the contacts. It also comes with three LEDs; red, green, and amber. The red LED indicates open circuit, the green LED indicates power ON, and the amber LED indicates a fault in the circuit. The device is UL or CSA rated for up to 200VAC and 500mA.

In terms of application field, the QS103XXHG220 is used in a variety of industrial and laboratory equipment. It is most commonly used to control or sense the presence of a power source or the occurrence of a fault in a circuit. For example, the device can be used to indicate when a circuit breaker is tripped, or when a relay has gone off, or when a motor is driving a load. Additionally, the device can also be used to indicate the presence of a high-voltage power source. This is especially useful in applications that require accurate and reliable indication of the presence of high voltage.

The working principle of the QS103XXHG220 is straightforward. The device is connected to a power source, a circuit, or both. Once the device is connected, it starts to measure the current and voltage levels of the circuit, and compares them to predetermined values. If the voltage or current readings are within the set limits, the device will indicate with one of the three LEDs. If the current and voltage readings are outside the limits, the device will trigger the alarm and alert the user.

The QS103XXHG220 is a reliable and cost-effective device for electrical applications. It is easy to install and requires minimal maintenance. Moreover, the device has low power consumption, meaning it will not create an extra burden on the power source. Thus, it is an ideal choice for many applications where control panels and other industrial equipment need to monitor power sources and/or identify faults in a circuit.
