Key features

Comprehensive Fault Detection: Detects single/multi-point grounding, AC intrusion, battery faults, and voltage imbalance in DC systems.

Real-time Voltage Monitoring: Displays system voltage, bus-to-ground voltage, and AC channeling voltage with alarm indicators.

Instantaneous Ground Recording: Records 8-channel waveforms at configurable frequencies (1KHz to 125Hz) for detailed fault analysis.

High-Precision Hardware: Uses 32-bit CPUs and 16-bit AD converters with 1000+ conversions per second and 0.01mA resolution.

Battery Circuit Monitoring: Locates faulty batteries and detects insulation degradation via Hall sensors and data collectors.

Flexible System Architecture: Supports up to 8 sensors per collector and connects via RS485 or Ethernet for easy installation.

Historical Data Storage: Automatically saves 2000 alarm records with date, time, impedance, and leakage voltage in EEPROM.

Advanced Self-Test Function: Performs module self-tests on power-up and continuously monitors bridge connection status.

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.
