Custom Power Distribution Units
Engineering-driven custom PDU solutions designed for high-voltage safety, system integration, and production-ready manufacturing.
What Is a Custom PDU
A Power Distribution Unit (PDU) manages and distributes electrical power within battery and energy systems. A custom PDU is designed to match system requirements such as voltage/current levels, physical layout constraints, integration with battery packs and control systems, and environmental & safety standards.
Our Role in Custom PDU Manufacturing
We focus on the mechanical and system-level manufacturing of custom PDUs—enclosure machining, sealing design, and integration readiness.
We align enclosure design with connector/busbar features, HV routing, sealing targets, and assembly sequence—so the PDU is manufacturable and repeatable.
PDU Enclosure Design
The enclosure is critical for safety and reliability. We support reinforced, compact, and manufacturable PDU housings designed to protect internal components.
- Aluminum and steel PDU housings
- Reinforced structural designs
- Compact space-optimized layouts
- Protection against mechanical stress
Material Selection and Processing
Material choice balances strength, weight, conductivity strategy, corrosion resistance, and long-term reliability.
We coordinate machining and surfaces to support sealing, corrosion resistance, and EMC grounding where required.
Precision CNC Machining for PDU Housings
High-precision machining ensures stable electrical interfaces and repeatable assembly. We machine connector and busbar mounting features, flat sealing surfaces, and complex internal geometries.
- Tight tolerance machining
- Connector & busbar mounting features
- Flat sealing surfaces
- Complex internal geometries
Electrical Interface Readiness
Mechanical design is coordinated with electrical system needs to reduce assembly errors and improve serviceability.
Thermal Considerations
PDUs may contain heat-generating components. We design housings with passive heat paths, integration options for cooling plates/heat sinks, and thermal isolation where required.
- Passive heat dissipation
- Cooling plate / heat sink integration
- Thermal isolation where required
- Stable operating temperatures
Sealing and Environmental Protection
Environmental protection is essential for PDU reliability. We support IP-rated sealing architectures, precision gasket/O-ring grooves, and controlled ingress points for cables and vents.
- IP-rated sealing architectures
- Precision gasket and O-ring grooves
- Controlled ingress points (cables & vents)
- Protection against dust and moisture
EMI and Electrical Safety Design
Custom PDUs must support electrical safety and EMC requirements. We consider enclosure features that support zone separation and grounding.
