Definition: Crosman is an electronic device that converts DC power to AC power, a process known as "crosstalk." It is used in many applications such as satellite navigation systems, military communications, and portable chargers. The term comes from the Greek word for "cross," which refers to the cross-shaped component of the device. Crosman has two main types: the CROS-102 (8V) and the CROS-205 (24V). They are both designed to be compatible with various AC power supplies, including rechargeable batteries. In terms of function, a CROS-102 can convert 8V DC power into 24V AC power when connected to an external source or charging station, while the CROS-205 can convert 24V AC power into 8V DC power. The device's primary advantage is its compact size and ease of use compared to other similar components in the market. The word "crosman" comes from Greek meaning "cross," which refers to the shape of the component that it converts, or the way a component works. In this context, the term can be used to describe any device that converts DC power into AC power.
