FAQ

What are the differences between SVG cabinets, APF cabinets, and capacitor compensation cabinets?

SVG cabinets are used for dynamic reactive power compensation and voltage stabilization (millisecond response). APF cabinets are used for harmonic mitigation (2nd-50th order harmonic filtering). Capacitor compensation cabinets are used for power factor correction. Choose a single cabinet type based on the project‘s main issue, or combine them for comprehensive management.

Can the protection rating of the complete cabinet be customized?

Yes. We support custom protection ratings including IP20 (indoor), IP40, and IP54. For harsh outdoor environments such as solar and wind power, high-protection outdoor cabinets can be provided with built-in air conditioning or industrial fans to handle high/low temperatures, salt spray, and dust.

Are complete cabinets tested before shipment?

Yes. Each complete cabinet undergoes full assembly, wiring, debugging, functional testing, and aging verification before shipment, ensuring plug-and-play installation on-site and reducing project timelines.

Can the complete cabinet connect to a cloud platform for remote operations?

Yes. The complete cabinet can be equipped with the Yidek Cloud platform, enabling remote monitoring, fault alerts, data reporting, and other intelligent operations. It supports multi-platform access via PC, mobile App, and WeChat mini-program.

What communication protocols do the complete cabinets support?

They support RS485 and Modbus protocols, with optional wireless communication methods such as 4G/WiFi, facilitating integration into existing monitoring systems or cloud platforms.
