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 rated voltage and current range for this relay?

It supports motors with rated voltage less than 690V (AC380V/AC660V) and rated current up to 820A.

Q:What types of faults can this motor protection relay detect?

It detects abnormal starting, overload, overcurrent, overheating, stalled rotor, phase loss, unbalance, under/over voltage, under/over power, and grounding or leakage.

Q:Does the relay support remote communication?

Yes, it supports MODBUS-RTU communication bus and can upload monitoring data and alarm status to remote control systems.

Q:What is the working power supply range?

The relay features an ultra-wide range working power supply of AC85-265V.

Q:How many digital inputs and outputs does it have?

It provides 4 digital outputs and 7 digital inputs, all of which can be programmed to set their functions.
