AI-Powered supplier vetting
SummaryThe supplier operates across pneumatic machinery, electrical and mechanical equipment, instruments, hardware, plastic products, and related manufacturing and sales activities. It reports CE and RoHS certifications and has conducted regular fire drills, but no factory environmental impact assessment report is available. Manufacturing resources include three production lines, while ongoing batch quantity reconciliation is not performed. R&D personnel support product development and production, but no auditable design documentation was available; three R&D patents are reported. The supplier has participated in an offline trade show and accepts FOB, CIF, CFR, and EXW terms, but reports zero countries served overseas. It does not provide OEM services for well-known brands and has no available SDK. Financial credibility cannot be positively established from the provided records because the reported financial figures are zero.
Supplier typeThe supplier is a manufacturer and seller covering pneumatic machinery and components, electrical instruments, power electronic components, hardware, plastic products, mechanical equipment, and related products. Its stated product keywords include overvoltage protectors, electricity meters, intelligent protectors, and guide-rail Tuya intelligent protectors, indicating a diversified industrial and electrical equipment supplier profile.
CertificationsCE and RoHS certifications are explicitly reported, providing evidence of certification coverage for the supplier's products. However, the supplier reports no factory environmental impact assessment report, so the certification evidence does not establish full environmental compliance at the facility level.
Financial creditThe provided financial records report zero operating revenue, operating cost, gross profit, operating profit, gross margin, and current ratio for the stated periods. These records do not provide positive evidence of operating financial strength or financial credibility.
Production capacityThe supplier reports manufacturing activities for pneumatic machinery, electrical instruments, architectural metal and plumbing components, plastic products, and hardware, supported by three production lines. However, it does not conduct continuous quantity reconciliation for every batch or mass-production run, indicating a stated production-control deficiency.
Product Q&A
Q:What are the unique advantages of the built-in 3 relays in this device?
A:
This device features 3 built-in independent relays. In the Tuya / Smart Life App, you can view the electrical data (Voltage, Current, Power) for Phase L1, L2, and L3 separately, and more importantly, you can switch the power ON/OFF for each phase individually. This is highly efficient for multi-route power distribution and sub-circuit management.
Q:Does this three-phase meter support bi-directional energy measurement?
A:
Yes, it supports accurate Bi-Directional Measure. It can monitor both forward energy (consumed from the grid) and reverse energy (generated back to the grid). This makes it an ideal solution for solar PV systems, energy storage storage systems, and net metering applications.
Q:Can it be used as a total circuit breaker for the whole system?
A:
Although this device provides comprehensive protection (over/under voltage, overcurrent, leakage, phase failure, etc.), it does not have a short-circuit isolation function. For the safety of the electrical line, you must install a standard circuit breaker (such as DZ47, C65) ahead of this device for short-circuit protection.
Q:What happens if one of the phases encounters an error, such as phase loss or voltage imbalance?
A:
The device features smart protection for Phase Loss, Phase Sequence, Voltage Imbalance, and Current Imbalance (configurable via the App). If any phase triggers the safety threshold, the device will respond within 0.5 seconds to protect your connected 3-phase machinery from damage.
Q:Can the protection parameters be adjusted manually without the App?
A:
Yes. While the App provides full configuration, you can also long-press the setting keys on the physical device panel to enter setup mode. You can adjust parameters like overvoltage (60-300V), undervoltage (80-210V), overcurrent (1-100A), and automatic reclosing delay time directly.
