Linear regulated power supplies
Linear regulated power supplies – For maximum voltage purity and industrial robustness
In industrial applications where maximum voltage quality, operational reliability and EMC immunity are essential, linear regulated power supplies remain irreplaceable. As one of the few manufacturers, FEAS offers an exceptionally wide range of linear regulated AC/DC power supplies – developed and manufactured in Germany.
Our linear power supplies are characterised by:
• Extremely low residual ripple (ripple < 2 mV)
• Noise-free, stable output voltage for sensitive electronics
• Fully encapsulated designs with protection class up to IP68
• Highest EMC immunity – no RF interference from switching pulses
• Robust technology with a wide temperature range (-40°C to +70°C)
• Short-circuit, overload and reverse polarity protection
• Ready for use in machine, measurement and control technology, radio, audio, laboratory and much more
Whether for 5 V, 12 V or 24 V applications – here you will find the right linear power supply for your requirements.
Select linear regulated power supplies now according to
• Output voltage: 5 VDC, 10 VDC, 12 VDC, 14 VDC, 15 VDC, 24 VDC
• Input voltage: 115 VAC, 230 VAC, 400 VAC single-phase, 3x400 VAC (three-phase)
Why linear regulation?
Linear power supplies offer decisive advantages over switching power supplies:
• No high-frequency interference – ideal for analogue electronics, audio and measurement systems
• Very fast regulation during load changes
• Proven technology – maintenance-free, durable, reliable
• Compatible with old PLC systems and sensitive controls
If you value interference-free power supply, long-term operational reliability and industrial robustness, our linear regulated power supplies are the best choice.
Typical areas of application
• Measurement and control technology
• Audio/HF technology (e.g. radio, broadcast, EMC-sensitive applications)
• Mechanical engineering
• Railway, transport and infrastructure technology
• Laboratory applications & test systems
• Telecommunications stations
• Shipbuilding, outdoor technology, plant control
Made in Germany. Made for your application.
All our linear power supplies are developed, tested and produced entirely in Germany. We don't just supply standard solutions – on request, we also offer customer-specific voltages, housings or additional functions.
Technical difference to switching power supplies
While switching power supplies operate with high efficiency, they often cause interference due to the switching principle and have complex EMC issues. Linear power supplies, on the other hand, are generally:
• Larger and heavier
• But completely interference-free
• Can be used without additional filters
• Suitable for the most sensitive devices
If every millivolt counts in your application, rely on FEAS linear power supplies.
