Specification-led OEM power supply development for factory automation, machinery and industrial control.

Industrial & Automation Power Engineering

Define the Power Platform Around the Equipment and Its Environment

PaiYi supports specification-led OEM power supply development for industrial equipment, from control cabinets and test instruments to production machinery. The electrical targets below remain open until the load profile, installation environment, target market and operating conditions are confirmed.

Mains EnvironmentGrid voltage, phase, frequency and transient conditions define the input environment.
Load ProfileContinuous, peak and inrush demands are specified around the equipment operation.
Control & SensingStable auxiliary rails support controllers, sensors, displays and communication.
Installation & EMCEnclosure, mounting, thermal and EMC conditions are reviewed together.

Industrial Power Supply Design Priorities

The final architecture should be selected from real system requirements rather than a fixed catalogue assumption.

Input and Output Definition

Confirm the input source, voltage range, phase and frequency, required output rails, regulation and sequencing expectations.

Power and Inrush Demand

Define continuous and peak loads together with inrush, motor or actuator start-up behavior across operating modes.

Isolation and Grounding

Review isolation boundaries, working voltage, grounding strategy, common-mode conditions and insulation coordination requirements.

Protection and Fault Behavior

Specify the required input, output and thermal protection behavior, fault reporting expectations and recovery method.

Temperature and Lifetime

Set the operating and storage temperature ranges, thermal constraints, cooling conditions and intended service-life target.

EMC and Certification

Evaluate emissions, immunity, surge and transient requirements together with the target industrial standards for the destination market.

Integration with the Equipment Environment

An industrial power supply operates inside a wider electrical system. Review of the surrounding equipment helps prevent late changes during validation.

System Context to Confirm

Machine and control cabinet conditions, motor or actuator start-up transients, grounding and isolation boundaries, nearby communication wiring, enclosure conditions, start-up and shutdown sequencing, fault states, and the target EMC test environment.

Frequently Asked Questions

Q
What environments do industrial automation power supplies need to survive?
Factory-floor supplies should handle 90-264 V AC input, wide temperature, harmonic and EMC noise, and mechanical vibration. PaiYi units target EN 55032 Class B and 3000 V AC isolation.
Q
Can you build power for PLCs, sensors and motor drives on one platform?
Yes. We define a shared power platform covering 12/24/48 V DC rails with peak capability for inrush and motor-start loads.
Q
Do you support custom form factors and DIN-rail mounting?
Yes. Electrical and mechanical options are part of our OEM/ODM scope, including DIN-rail, chassis and enclosed variants.
Q
What certifications matter for industrial power supplies?
CE (LVD/EMC) to EN/IEC 62368-1 with CB test reports; UL/ETL listing is arranged with the buyer or quoted per project.
