Adjustable 99 gear power with real time display The gear power is adjustable in 99 steps, and the current setting is shown in real time on a digital tube for easy monitoring and precise control. Robust electrical performance Built with frequency capacitance and low internal resistance, delivering stable performance. Temperature resistance up to 105 C supports reliable operation in demanding conditions. Real time protection indicators Real time voltage protection: if the input voltage is outside the 817 V range, the UE indicator will be displayed. Temperature monitoring: if the MOStube temperature exceeds 45 C, the CE indicator will be displayed. Compatibility and practical use Designed to operate with input voltages in the 817 V range, making it suitable for 12 V systems and other DC power setups. Use scenarios Automotive accessory power management: optimize power delivery in cars or motorcycles while monitoring voltage and temperature. Portable DC projects and field work: manage and monitor DC power in remote or outdoor environments where voltage can vary. Solar and batterypowered systems: integrate into small DC setups that require adjustable power with realtime status indicators. Notes Size and material details are not specified in the provided information. The description focuses on function, protection features, and realtime status indicators consistent with the original MOStube specifications.
