URA provides an autonomous mode of operation of batteries, which allows one of them to be used to power additional devices, such as a car radio, refrigerator, lighting devices, etc. when the car engine is not running. This eliminates the discharge of the main battery, which is necessary for a reliable engine start. URA are used on cars, as well as on sea vessels with on-board voltage 12V and 24V (URA 120). URA 120 URA 120 is a diode decoupling that allows you to isolate batteries from each other, providing them with a charge from one generator. The maximum load current is selected in accordance with the maximum generator current and should be no more than 120A. When using URA 120 with some types of generators, there may be a voltage drop in the vehicle's on-board network. This happens when working with generators, in which an integral voltage regulator ("tablet" with a brush assembly built into the generator) is installed, which is not separable with a brush holder. In such cases, together with the URA, it is recommended to use an external voltage regulator (673.3702) with an increased setting voltage. The devices are made on an aluminum heat sink with sealing of the mounting elements with a special resin, which ensures high reliability of the devices. URA 200 URA 200 is a power relay with a built-in microcontroller, which avoids voltage drops and does not require additional installation of an overvoltage regulator. The use of URA 200 also allows the use of a second battery when starting the engine in the cold season (provided that the battery1 is not deeply discharged). URA 300, URA 6 00 URA 300 and URA 600 are designed to connect additional high-power devices (winches, powerful starters, etc.). The devices are contactors with control units with built-in microcontrollers, which allows them to switch significantly higher currents than the URA 200. Otherwise, the principle of operation of these devices and URA 200 is the same. Connecting and disconnecting the second battery, when using the URA 200, URA 300 and URA 600, occurs automatically, when the voltage of ≥13.2V and ≤12.8V is reached and held on the main battery for 6 seconds, respectively. For forced connection of the second battery, the devices have a special “start” terminal.
