Using the innovative Power Supply Kit (PSK), SCHIEDERWERK designs and manufactures power supplies and switch-mode power supplies with custom-made outputs – fast, precise, and reliable. Our platform-based, modular approach accelerates your development, lowers costs, and mitigates project risks, all while maintaining the highest standards of quality and safety. It also offers maximum form factor flexibility to seamlessly support your design-in process.

Our platform integrates pre-engineered, EN 60601-certifiable standard modules with tailor-made circuit designs. This enables an efficient configuration of both AC/DC and complex switch-mode power supplies – delivering maximum design freedom and full regulatory compliance, perfectly suited for advanced medical equipment and power management systems in regulated industries.

Technical specifications for our medium-power Switch-Mode Power Supplies (depending on project):

• Output power: 300 – 3,600 W

• Output voltage: 0 – 60 V

• Output current: 0 – 40 A

Key Features

• Multiple Outputs

  If several different or separate output voltages are required in an application, integrating all voltage transformers in a single device is the more cost-effective alternative.

• Reinforced insulation

  To isolate the outputs from the mains and earth potential, we offer insulation systems with UL and IEC approval that meet the safety requirements for medical technology.

• Medical approval

  The requirements regarding EMC, mains behavior (hold time), leakage currents and insulation for certification to IEC/UL 60601 are met.

• For global use

  The particularly high efficiency of the front end (PFC) enables the power supply units to be used worldwide without any power restrictions (derating) and fulfills all country-specific requirements with regard to THD and EMC.

• Cost-effective Solution

  We achieve your cost targets by implementing only the circuit functions that you really need, by integrating all functions (multiple outputs, power management) without overhead and by consistently optimizing the components. For corresponding quantities, we offer solutions that cost less than standard.

• Many communication interfaces

  On request, we can integrate an interface for communication so that integration into the application’s power management system is possible (examples: CAN, PMBus, SMBus, RS485).
