C41-ALP2-NAO

C41-ALP2-NAO is an LED-based unit manufactured by ABB, a leading provider of automation and electrical products. This panel indicator consists of two LED lamps, one green and one red, with a built-in reset button and a 500mA power connection. It is designed to provide the user with a visual indication of operations such as system fault and warning, short-circuit protection, and over-temperature protection. This unit is commonly used in industrial control, automotive, commercial HVAC, and other professional applications.

The panel indicator works by indicating the intensity of light produced by the two LED lamps. The LED lamps are connected to the power supply via DC voltage. The current intensity of the LEDs is relayed to the user via the two circles, each indicating a different status. The green circle will light up when the maximum voltage is not exceeded while the red circle will light up when the maximum voltage is exceeded.

The reset button on the C41-ALP2-NAO is used to reset the maximum voltage level. This can be done by shorting the power terminals and then pressing the reset button. This will reset the maximum voltage to the predetermined level. If the power is still on when the reset is done, the green circle will stay illuminated until the designated voltage level is exceeded.

The C41-ALP2-NAO is an economical and reliable panel indicator. It is designed to be used in harsh environments, as the LED lamps are protected by an IP67 grade enclosure. The product is CE, CB and UL listed and meets the ISO 9000 and RoHS standards. This is an important factor while buying as it means that the product is reliable and high-performance.

The C41-ALP2-NAO is one of the most widely used panel indicators today, as it provides great value for money. The product is ideal for use in industrial control, automotive, commercial HVAC and other professional applications. It is designed to last for a long time, thanks to the strong and durable IP67 grade and other protective features. Overall, this product is a great choice for those who need an economical yet reliable indicator solution.
