Got Questions?

Frequently Asked Questions

Key technical inquiries from international project contractors.

Q: Can the cabinet support customization for specific camera voltages?

Yes. The system provides both stabilized -48VDC and pure sine wave 220VAC/230VAC outputs. Additional DC-DC step-down converters (12V/24V) or PoE injectors can be easily integrated onto the standard 19-inch DIN rails.

Q: How does the system handle high desert temperatures?

The cabinet utilizes an internal closed-loop industrial air conditioner (MAC600W) capable of operating at up to +55°C ambient temperature, keeping internal battery and module temperatures within their optimal lifespan range (<30°C).

Q: What certifications are provided for sea freight customs clearance?

We provide full documentation packages including UN38.3 test reports, MSDS, sea transport condition appraisals, and official Maritime Dangerous Goods Packaging Inspection Certificates.
