It adopts a transformer design and measures AC single-phase power (rated voltage 220V, current 10A-250A) through a current transformer to achieve high-precision power statistics and management. It is suitable for energy consumption monitoring in residential and commercial power consumption scenarios.
Plastic housing (such as fiberglass or flame-retardant PC) can effectively protect the meter from physical impact, environmental corrosion and human damage. For example, the rainproof design (IP44 protection level) prevents rainwater intrusion, and the transparent window design facilitates reading while preventing illegal operation.
Plastic materials (such as SMC glass fiber reinforced plastic) provide high insulation resistance (≥20MΩ), and flame retardant performance (UL94 V0 level) can prevent short circuit fire, ensuring safe operation in an environment of -25℃~+50℃ and avoiding the risk of electric shock.
The material is corrosion-resistant and aging-resistant, suitable for outdoor or humid environments (humidity ≤ 80%), with a service life of more than 30 years, reducing maintenance requirements, and the concealed wiring design simplifies the construction process.
Frequently Asked Questions (FAQ)
Q1:
What materials are used in these metering boxes and what are their benefits?
The boxes use non-metallic materials like SMC (glass fiber reinforced plastic) or PC+ABS. These materials provide high insulation resistance (≥20MΩ), flame retardancy (UL94 V0 level), corrosion resistance, and physical impact protection.
Q2:
Are these metering boxes suitable for outdoor use?
Yes, they are designed with an IP44 protection level, which is rainproof and dust-resistant. They operate reliably in temperature ranges from -25℃ to +50℃ and humidity levels up to 80%, giving them a service life of over 30 years.
Q3:
What is the difference between the TY-SXD and TY-PXD models?
The TY-SXD models utilize SMC non-metallic material for their enclosures, while the TY-PXD models are built with PC+ABS non-metallic material. Both offer high-performance insulation and protection.
Q4:
What is the rated voltage and current capacity for these metering boxes?
They are configured for AC single-phase power with a rated voltage of 220V and support current ranges from 10A up to 250A through high-precision current transformers.
Q5:
How do these boxes prevent electricity tampering?
They feature a durable plastic housing with a transparent window design. This allows for easy meter reading while preventing unauthorized physical access or illegal operations inside the box.
