Typical Power Architecture

Customer Challenge

Developing a power solution for compact medical equipment required overcoming several engineering challenges.

1. Limited Internal Installation Space

The handheld diagnostic device required an internal power supply design with minimal size and optimized mechanical integration.

Traditional external adapters could increase overall system size and reduce portability. Therefore, the customer needed a compact open-frame architecture that could be directly integrated into the device enclosure.

2. Medical Safety Requirements

Since the equipment was designed for healthcare environments, electrical safety was a critical requirement.

The power solution needed to support medical application requirements, including:

Low leakage current design
Enhanced electrical isolation
IEC/EN 60601 safety considerations

The customer needed a power platform suitable for medical device development rather than a standard consumer-grade adapter.

3. Stable Power for Sensitive Electronics

The handheld diagnostic system included sensitive electronic components such as:

Sensors
Embedded processors
Display modules
Signal processing circuits

Power instability, ripple, or electrical noise could affect system reliability and measurement accuracy.

The customer required stable DC output performance with optimized noise control.

4. Reliable Operation for Daily Healthcare Use

Although the device was portable, it was expected to support frequent daily operation in clinical and healthcare environments.

The power solution needed to provide reliable performance during repeated usage cycles while maintaining thermal and electrical stability.
