Linear power supplies

Linear power supplies up to 1 watt

The special advantage of a transformer power supply compared to commercially available switching power supplies is the low residual ripple.

arnotec GmbH is a manufacturer of small and compact linear regulated power supplies with different output voltages and low current consumption. Our functional power supplies can be used in analogue measurement technology and in analogue audio applications. Due to the analogue design with transformer and linear regulator, the power supplies are very low in interference and have a low residual ripple. The power supplies are available with a power of 0.5 W or 0.5 VA and are equipped with fixed voltages of 1.5 V, 3.0 V, 3.4 V and 5.0 V. (Output voltages available on request +4.5 V, +6.0 V and +9.0 V).
With the two mounting brackets on the housing, the power supply unit can be easily mounted on the wall or ceiling. Mounting material can be ordered separately.
