Features: Featuring a 12.5V/0.4F specification, it provides instantaneous power for devices, smart meters and similar equipment. During power outages, it enables rapid power supply switching ensuring data integrity. The compact module dimensions (specific measurements to be supplemented) make it suitable for space-constrained embedded systems, such as electric actuators and automotive electronics applications. Features lightweight construction (approximately 35-569g compared to similar products), facilitating integration into mobile devices. Operates reliably within extreme temperatures from -40°C to +65°C, meeting demanding conditions for outdoor monitoring. Supports rapid charging/discharge cycles; its 0.4F capacitance delivers instantaneous high current (up to 100A compared to similar products), making it suitable for short-duration, high-load applications.
