4090V to 36V 3A 108W Converter — Solar Voltage Reduction Power Module A reliable DCDC stepdown converter designed to convert highervoltage solar array output down to a stable 36V supply. This module accepts 40–90V input and delivers a regulated 36V output at up to 3A (108W). It is ideal when you need to power 36V equipment from highervoltage PV strings or other DC sources while protecting downstream devices from overvoltage. Key benefits Matches voltage solar arrays to 36V loads: lets you use longer panel strings or higherVOC modules while supplying a stable 36V output for devices rated at 36V. Protects equipment and simplifies system design: replaces complex wiring or multiple panels in parallel by stepping down voltage reliably to the needed level. Predictable power delivery: rated for up to 3A and 108W continuous within specified input range, making it suitable for many 36V DC appliances and modules. Easy integration: compact module form factor fits into custom enclosures and wiring harnesses for solar or industrial projects. Key attributes Functionality: DCDC buck (voltage reduction) converter specifically set to output 36V from a 40–90V DC input range. Input compatibility: designed for solar panel strings or other DC sources with a voltage between 40V and 90V. Output specifications: fixed/regulation to 36V DC, maximum output current 3A, maximum output power 108W. Performance: stable regulated output when used within specified input range and output load limits. Installation: compact power module intended for mounting inside an equipment compartment or enclosure; follow good wiring and cooling practices for reliable operation. Typical applications / use cases Solarpowered 36V lighting arrays: step down a voltage PV string so it can reliably feed a 36V LED driver or lighting bank without reconfiguring panels. 36V equipment from rooftop or offgrid arrays: power small pumps, controllers, communications gear, or other 36V devices from a highervoltage solar array. System retrofits and conversions: integrate newer highervoltage panels into legacy 36V systems without replacing loads or rewiring panel configurations. Installation and safety notes Verify input voltage: confirm the module's input is within 40–90V before connecting. Exceeding the input range can damage the module and connected equipment. Respect output limits: do not draw more than 3A or exceed 108W output to avoid thermal or electrical overload. Provide cooling and ventilation: install the module in a location with airflow and avoid enclosing it in a tightly sealed space without heat dissipation measures. Use appropriate fusing and wiring: install correctly sized input and output fuses or breakers and verify polarity before powering up. Professional installation recommended if you are not familiar with DC solar wiring and safety practices. What this module delivers A straightforward, purposebuilt solution for stepping down 40–90V DC to a regulated 36V DC output at up to 3A (108W). Use it whenever you need to bridge highervoltage solar or DC sources to 36V equipment with predictable, continuous power delivery.
