What type of voltage does the AN/UPX-37 Interrogator Set require to operate?

The AN/UPX-37 Interrogator Set requires low voltage direct current (VDC) to operate effectively. This type of voltage is commonly used in electronic equipment because it can be safely supplied from batteries or low voltage power sources, making it suitable for portable or field-deployable systems like the AN/UPX-37.

Low voltage direct current power ensures that the equipment operates efficiently without the risks associated with higher voltage systems, such as overheating or electrical hazards. Moreover, the ability to run on low voltage allows for greater flexibility in terms of power supply sources, which is particularly valuable in military applications where reliability and safety are paramount.

While other options involve alternating current or high voltage, these are not ideal for the specific operational requirements of the AN/UPX-37, which is designed for use in environments where low voltage direct current provides adequate performance and minimizes potential risks.
