Key benefits and features - Reliable output capability: rated output power is 12V x 5A = 60W. The actual output power depends on the power available from the installed battery. - Easy battery maintenance: no welding required; batteries can be freely disassembled and replaced. - Installable battery capacity: 6 x 3.7V x 3400mAh = 74 watt hours (battery pack supplied by the user). - DC constant voltage UPS with automatic management: provides automatic charging and discharging control without manual operation. Multiple output voltages are supported (5V, 9V, 12V) for compatibility with common devices such as optical tracing equipment, routers, and monitoring cameras. Applications and use scenarios - Optical tracing systems that require stable 5V/9V/12V power to maintain accuracy and reliability. - Network routers and related networking equipment that need uninterrupted power during outages. - Surveillance cameras and other monitoring devices that benefit from automatic UPS management and consistent voltage output. Performance and compatibility notes - Function: DC constant voltage UPS with autonomous charge/discharge control. - Compatibility: supports 5V, 9V, and 12V outputs; uses an installable user-supplied battery pack (6 x 3.7V 3400mAh cells, 74 Wh total). - Replacement and maintenance: battery modules are user-serviceable without welding, enabling easy replacement.
