Key Features Premium Material: This product is made of selected high-grade plastic and hardware, along with the baking paint process, which not only imparts corrosion and rust resistance but also ensures a robust construction that resists deformation, safeguarding the product's long-lasting practicality and durability. High Precision: The four-digit display and 0.5% high precision adjustment allow you to easily adjust the output voltage and output current to meet your various demands. Wide Compatability: The product is capable of automatically switching between C.C and C.V modes according to the connected load. You can switch the voltage button to make the product adapt to 230V±10% or 115V±10% voltage, which gives it a wider range of applications. Safety: The product utilizes several safety measures, including grounding wire, leakage protection, overheating protection, voltage overload protection, power overload protection, and short circuit protection. Application It is suitable for battery charging (lithium iron phosphate batteries, lead-acid batteries, etc.), electronic product charging, electronic product maintenance, communication equipment maintenance, electrolysis, electroplating, electro-brush plating, bulb testing, aging test, production line test, DIY, laboratory, school, laboratory research, and teaching.
