Device УСЛН250МБ is designed to give an alarm in case of critical state of a nickel-cadmium battery caused by its heating up to (65 ±2) °C, as measured by temperature sensor, or in case of voltage unbalance between two storage battery groups (10 pcs. each) caused by internal short circuit of individual batteries or impermissible voltage increase in the process of charging. The battery is equipped with a temperature sensor. The device receives at its input signals from the temperature sensor and voltage from the two storage battery groups. The device is provided with a self-test feature for pre-flight check-up.
