Medical Power Engineering

Define the Power Platform Around the Device and Its Clinical Environment

PaiYi supports specification-led OEM power supply development for medical and healthcare devices, from diagnostic instruments to monitoring and therapeutic equipment. The electrical targets below remain open until the device class, isolation strategy, target market and operating environment are confirmed.

Mains EnvironmentGrid conditions, earth leakage and transient requirements define the input environment.
Device Power PathAuxiliary conversion, isolation and standby behavior are specified around the device architecture.
Patient & Operator SafetyIsolation, leakage current and protection requirements follow the applicable standard.
EMC & Clinical SettingEmissions, immunity and system integration are reviewed for the intended environment.

Medical 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, required output rails, regulation, ripple and sequencing expectations.

Isolation and Leakage Current

Review isolation boundaries, working voltage, creepage and clearance, and patient- and operator-touch leakage limits.

Power and Thermal Demand

Define continuous and peak loads together with thermal constraints, cooling conditions and duty cycle.

Protection and Fault Behavior

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

Standards and Compliance

Confirm the applicable medical electrical safety standard, classification and certification strategy for the destination market.

EMC and System Integration

Evaluate emissions, immunity, surge and transient requirements in the actual clinical installation environment.

Integration with the Clinical Environment

A medical power supply operates inside a regulated electrical system. Review of the surrounding device and installation helps prevent late changes during validation.

System Context to Confirm

Device class and applied part definition, grounding and isolation boundaries, leakage current strategy, nearby equipment and communication wiring, enclosure conditions, start-up and shutdown sequencing, fault states, and the target EMC test environment.

OEM Development Scope

The project scope is defined jointly and documented before sampling.

Electrical and Mechanical Options

  • Input and output configuration
  • Power, isolation and leakage targets
  • Protection and thermal design scope

Frequently Asked Questions

Q
What certifications are required for medical device power supplies?
Medical power supplies are designed and built toward IEC 60601-1 (3rd edition) with 2xMOPP patient isolation, designed and built toward IEC 60601-1 (3rd edition) with 2xMOPP patient isolation and design targets for low leakage current in normal and single-fault conditions. IEC 62368-1-based platform options are available. We do not currently hold IEC 60601-1 certification; where a project requires it, certification is arranged with the certification body you nominate before production. PaiYi designs to these levels for both patient-contact and non-patient-contact equipment, with certification pursued per project.
Q
Can PaiYi supply power for both patient-contact and non-patient-contact devices?
Yes. We deliver isolated supplies for patient-contact applications (BF/CF type) and cost-optimised units for non-patient-contact systems, all on a specification-led OEM/ODM flow.
Q
Do you offer custom medical power supply development?
Yes. Our OEM/ODM scope covers input/output definition, thermal and EMC design, mechanical integration and sample validation against your clinical environment.
Q
What is the typical lead time for custom medical PSU projects?
Requirement review to architecture proposal usually runs a few weeks; sample validation follows your certification plan. Contact our engineering team for a project timeline.
