DC Distribution Panel

DC Distribution Panel

Direct current power distribution unit engineered to centralize circuit protection, power routing, and distribution across industrial, telecommunication, and renewable energy systems.

Product Overview

 

Direct current power distribution unit engineered to centralize circuit protection, power routing, and distribution across industrial, telecommunication, and renewable energy systems. Built with electrolytic copper busbars and modular DIN-rail mounts, the assembly manages high-amperage DC feeds while maintaining low contact resistance. Enclosures utilize 1.5mm to 2.0mm cold-rolled steel or SUS304 stainless steel with exterior-grade polyester powder coating, protecting internal electrical components against environmental exposure.

Key Features

 

Optimized Thermal Distribution: Internal component spacing and busbar layouts prevent localized hotspots during continuous high-load operation.

Modular Configuration: Accommodates mixed-pole breaker arrangements and shunt trips for remote monitoring integration.

Secure Termination: Tin-plated electrolytic copper busbars minimize galvanic corrosion at terminal connection points.

Clear Circuit Identification: Laser-etched nameplates and DIN-rail labeling correspond directly to supplied wiring schematics.

 

Applications

 

Solar Photovoltaic (PV) Systems: Combines and distributes DC strings from solar arrays prior to inverter input.

Telecommunications: Manages -48V DC power distribution racks for cellular base stations and data centers.

Industrial Automation: Supplies regulated DC power to PLC racks, actuators, and emergency shutdown loops.

Energy Storage Systems (BESS): Manages battery rack feeds and isolation for commercial energy storage units.

 

Customization

 

Engineered to integrate directly into existing cabinet footprints and electrical schemas.

 

Mechanical Adjustments: Custom enclosure dimensions, mounting hole patterns, and specific color finishes via RAL powder coating.

Electrical Modifications: Tailored busbar sizing, specific circuit breaker brand integration (ABB, Schneider, Eaton, Siemens), and integrated monitoring sensors (Hall-effect current transducers, voltage meters).

Engineering Deliverables: 2D/3D CAD models (STEP/IGES) provided within 48 hours of specification confirmation.

 

Manufacturing & Quality Control

 

Production relies on standardized sheet metal fabrication and rigorous electrical testing.

 

Fabrication: CNC laser cutting (Amada) and CNC bending ensure precise enclosure tolerances (+/- 0.2 mm).

Busbar Processing: Automated CNC copper busbar punching and bending machines ensure exact hole alignment and low-resistance bends.

Testing Protocol: Every panel undergoes 100 percent factory acceptance testing (FAT), including 2.5kV dielectric withstand voltage testing, insulation resistance checks, and mechanical operation verification of all breakers and fuses.

 

Certifications & Documentation

 

Standards Compliance: Designed and manufactured in accordance with IEC 61439-2 and UL 891 standards (dependent on regional configuration).

Material Traceability: Mill test certificates (MTC) supplied for copper busbars and structural steel.

Shipped Documentation: Wiring schematics, terminal layout diagrams, bill of materials (BOM), and factory test reports delivered with every shipment.

 

Packaging & Delivery

 

Export Packaging: Secured on ISPM 15 compliant heat-treated wooden pallets, wrapped in anti-corrosion VCI film, and edged with high-density foam corner protectors to prevent transit vibration damage.

Lead Time: Standard configurations ship in 3 to 4 weeks; custom-engineered projects require 5 to 6 weeks from drawing approval.

 

FAQ

 

Q: What is the maximum short-circuit current rating (SCCR) of this panel?

A: Standard units are rated up to 35kA or 50kA SCCR, determined by the main breaker interrupting capacity and busbar bracing configuration specified in your project requirements.

Q: Can the panel accommodate third-party circuit breakers specified by our engineering team?

A: Yes. Mounting rails, internal depths, and busbar connection fingers can be configured to accept specific brands and models designated by your electrical schematics.

Q: What surface treatment is applied to the steel enclosure for outdoor applications?

A: Outdoor units undergo iron phosphating pretreatment followed by an exterior-grade polyester powder coat (minimum 80-micron thickness), salt-spray tested to 1000 hours per ASTM B117.

Q: Are digital monitoring meters included for remote voltage and current tracking?

A: Digital multimeters or DC energy meters with Modbus RTU (RS485) communication ports can be factory-integrated into the front door assembly based on project specifications.

Q: What documentation is provided to support our site commissioning process?

A: Each shipment includes as-built electrical schematics, terminal strip mapping, individual component data sheets, and signed factory test records.

Q: How do you prevent busbar joint oxidation over long operational lifecycles?

A: All copper busbar contact surfaces are electro-tin plated, assembled with Belleville spring washers to maintain constant contact pressure, and torqued to calibrated engineering specifications.
