Is electrical safety compromised if a different DC connector is fitted?
In many cases, the "Critical Component List" in the safety report lists "various" for the output connector, or the connector is not explicitly listed. This means that any connector may be fitted.
Can a different connector be fitted to a desktop power supply?
Yes, this is possible by arrangement. Typical minimum order quantities (Far East production):
- up to 60 W: MOQ 500
- up to 90 W: MOQ 300
- from 200 W: MOQ 100
Modifications in Germany are available on request.
What is the difference between ITE/industrial and medical power supplies?
Many electrical characteristics of ITE and medical power supplies, such as power, output voltages, and form factor, are often very similar. The key difference, however, lies in the safety requirements. Medical power supplies meet stricter requirements regarding clearance and creepage distances as well as leakage current, providing a higher level of safety.
What is the difference between Protection Class I and Protection Class II power supplies?
The power supply shuts down at startup or cannot supply the load. Why?
This is likely due to excessive inrush load (overload at the moment of startup).
- Use a more powerful power supply
- Use a power supply with a higher peak current rating
- Use a power supply with constant-current function
What information is required for a power supply inquiry?
Please describe your application in a few sentences so we can find the right solution. Basic information required:
- Input voltage (e.g. 100–240 VAC, including tolerance range)
- Output voltage(s) and required currents (including continuous and peak power)
- Device type: ITE (EN 62368-1), medical power supply (EN 60601-1), or special standards
- For desktop power supplies: connector type and cable length
- Form factor: open frame, desktop, or enclosed power supply
- Cooling: fan-cooled or fanless
- Ambient temperature (including derating at high temperatures)
- Special EMC standards and power factor correction (PFC class A–D)
- Ripple & noise
- Service life and MTBF
- Mechanical requirements: mounting orientation, dimensions, IP rating
I need a replacement part – what information is required for a replacement desktop power supply?
To find a suitable replacement unit, we need the following information:
- Photo of the type label, the cable harness, and the entire unit
- Sketch or drawing of the cable harness with cable lengths and connector types
- Desired quantity
