Why does the converter shut down output? What are the input voltage protection thresholds?

Input under-voltage protection triggers below 10V. Input over-voltage protection triggers above 15V. Under both conditions, output cuts off and indicator turns red. Normal startup requires input voltage between 10-15V.

How to select the correct model? What are the available current & power options?

Available models: 1224-10A(240W), 1224-20A(480W), 1224-30A(720W), 1224-45A(1080W), 1224-60A(1440W), 1224-80A(1920W). Please select according to your actual load current and power demand. Please also use the matched wire gauge shown in manual.

What applications is the JXSY1224 series boost converter suitable for?

AI-Powered supplier vetting

SummaryZhejiang Juxing New Energy Co., Ltd. is a China-based limited company established in 2022 with 21 employees and a business scope covering new-energy equipment, batteries, photovoltaic equipment, power electronics, electrical instruments, and related technical services. It reports CE, RoHS, and other certifications, broad customization services, new-product development during the past year, inventory capability, and a high export-sales share. However, the provided information identifies no ODM service, SDK, overseas warehouse, overseas showroom, valid manufacturing contract with related subcontractors, written supplier-service procedures, environmental impact assessment report, or recent regular fire drills. Finished products are checked by packing staff, and customer cases are not provided.

Supplier typeThe supplier is a combined limited company based in Zhejiang, China, established in 2022, with 21 employees. Its stated scope spans new-energy dynamic and photovoltaic equipment, batteries, transformers, power electronics, switchgear, electrical instruments, equipment leasing, and technical services, indicating a manufacturer and technical-service provider rather than a narrowly specialized trading entity.

CertificationsThe supplier reports holding CE, RoHS, and other certifications. These certifications provide explicit evidence of certification coverage, although the specific products and scope of the additional certifications are not identified.

R&D capabilityThe supplier states that it introduced new products during the past year and provides technology development, consultation, exchange, transfer, and solar or energy-storage technical services. It does not provide an available SDK and does not offer ODM services, so the evidence supports product-development capability but not software-development or ODM capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These repeated service declarations provide direct evidence of broad customization coverage.

Product Q&A

Q:What is your sample policy?

We can provide samples if ready parts are in stock, but sample and delivery fees will be charged.

Q:How about your delivery time?

The specific delivery time depends on the items and the quantity of your order.

Q:Do you offer OEM/ODM service?

Yes. We offer customization services to meet your unique requirements and preference.

Q:What will happen if positive and negative input terminals are reversely connected?

Built-in reverse-polarity protection with internal fuse.The fuse will blow automatically to protect your battery when input positive and negative are reversed.

Q:When will the over-temperature protection be triggered? What is the fan working logic?

When heat-sink temperature exceeds 85 centigrade, output will shut off automatically with red light on. Output recovers after cooling down below 85 centigrade. The cooling fan auto-turns on above 45 centigrade and auto-turns off below 45 centigrade.
