AI-Powered supplier vetting

SummaryChongqing Blue Jay Technology Co., Ltd. is identified as a Chinese limited company and manufacturer/factory, although another record describes the business as a trading company. It reports ISO 9001 certification and references CE, RoHS, and after-sales quality control. The supplier states that it provides OEM and ODM services, has launched new products within the past year, and supports extensive customization. Production-related evidence includes two factories and more than 20,000 m² of area, while in-stock fulfillment, overseas warehouses, overseas showrooms, and overseas agents or branches are explicitly unavailable. The supplier has an export license and serves Vietnam and Malaysia, with participation in the Canton Fair. Financial information is insufficient to assess credibility, and raw-material traceability is unknown. OEM service for well-known brands is reported, but no specific customer names or cases are provided.

CertificationsThe company description explicitly states that Blue Jay is ISO 9001-certified and references CE and RoHS in its quality-control approach. The provided information does not clarify the scope, issuing bodies, or validity dates of these certifications.

After-Sales capabilityThe company description explicitly mentions after-sales in its quality-control coverage. However, no detailed service process, response standard, warranty terms, or support organization is provided, so the overall capability cannot be fully assessed.

R&D capabilityThe supplier reports new products during the past year, ODM service, design optimization support, and multiple customization modes. It has no available SDK, so software-development support is explicitly absent, but the product and design evidence supports innovation capability in hardware or product development.

Production capacityThe supplier describes two factories with more than 20,000 m² of area and is identified as a manufacturer/factory. It also explicitly lacks in-stock capacity, overseas warehouses, and overseas showrooms, while contract status for manufacturing capacity is unknown.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and states that it can help optimize designs. These records provide direct evidence of broad customization capability.

Product Q&A

Q:What is the maximum response time for arc fault isolation?

The AFR-4 relay offers ultra-fast response with pure arc trip under 8ms and combined current+arc trip under 15ms. The relay output speed can reach up to 5ms.

Q:How many arc detection channels does the AFR-4 support?

The device supports 4 channels of arc signal detection. It can connect to ST visible light and ST ultraviolet sensors via optical fiber.

Q:What communication protocols are supported for remote monitoring?

It features an integrated RS485 interface with Modbus RTU protocol, enabling seamless remote monitoring and control in modern power distribution systems.

Q:What is the operating power supply range for this relay?

The standard power supply is AC/DC 85~265V. An optional 48VDC power supply is also available to meet different installation requirements.

Q:Does the relay provide protection against circuit breaker failure?

Yes, the AFR-4 includes circuit breaker failure protection features along with regional arc light detection and flash warning mechanisms.
