Overview Power Supply

Specialized in linear power supplies

In times of energy saving and the trend to make power supplies smaller and lighter, the linear regulated power supply with a transformer as a safe separation of the mains voltage is going out of fashion. Nevertheless, this power supply also has advantages over modern regulated switched-mode power supplies.

Often, transformer power supplies cannot simply be replaced by switched-mode power supplies. This even becomes audible if one wants to operate an audio amplifier with such a switched-mode power supply without special precautions. But it is not only in the audio field that the power supply can have an unpleasant influence on the application. Also in control engineering or with particularly sensitive sensors, a constant and low-noise power supply is virtually a prerequisite for a good result.

arnotec GmbH has a great deal of know-how in the manufacture of linear regulated power supplies with different output voltages and low current consumption.

Our power supplies are used in analogue measurement technology, for supplying sensors or in the analogue audio sector. Due to the compact design with transformers and series regulators, the power supplies are very low-noise and have a low residual ripple. Our power supplies are available with a power of 0.35 VA or 0.5 VA and are equipped with the fixed voltages 1.5V / 3.0V / 3.3V and 5.0V. Other voltages on request.

Advantages

linear regulated transformer power supplies
  • low-noise output voltage as no switching regulator is used
  • short settling time for voltage and current
  • statistically low probability of failure due to the simple design
  • short circuit proof
