ZK SJ30 Power Module Key benefits — why you need it Improve battery charging and device runtime: the ZK SJ30's builtin MPPT function optimizes energy conversion to get more usable power from your source, helping batteries charge faster and devices run more efficiently. Reliable under load: low internal resistance MOS tubes and enlarged heat sinks reduce heat buildup and improve thermal stability during sustained or heavy use. Easy to integrate and adjust: designed for practical installations and onsite tuning without tools, so you spend less time setting up and more time using the system. What it does (core functions) MPPT power management that continuously tracks and optimizes input conditions for efficient energy conversion. Adjustable DC power output for use as a regulated supply. Battery charging control to improve charge efficiency and reduce wasted input power. LED constantcurrent driving capability for stable lighting performance. Standout attributes Performance: MPPT optimization for higher charging and powering efficiency; robust thermal design to maintain steady operation under load. Components: uses low internal resistance MOS tubes to reduce losses and enlarged heat sinks for effective dissipation of heat. Usability: screwdriver potentiometers allow quick, tool adjustment of MPPT voltage, output voltage, and current limit settings. Compatibility: suitable for systems needing adjustable DC power, controlled battery charging, or LED constantcurrent driving. How it solves problems Reduces wasted input energy and shortens charge times by actively optimizing power transfer with MPPT. Prevents thermalrelated failures and maintains stable output under heavy use by combining MOS components with improved heat sinking. Simplifies field tuning and maintenance by enabling precise adjustments without opening the enclosure or using tools. Typical applications Solarplusbattery systems: maximize energy harvested from panels and deliver more efficient battery charging under changing solar conditions. Laboratory or workshop DC supplies: provide an adjustable, regulated DC source with current limiting and precise output control for testing and prototyping.
