Product description

This switching power supply converts mains voltage into a stable 3.3 V DC voltage and is suitable for operating low-voltage circuits and microcontroller boards with a corresponding power supply. The device is designed for continuous operation and works with input voltages of 230 V AC at 50 or 60 Hz.

With a maximum output power of just under 10 W at 3 A, the power supply provides enough current for sensor networks, simple control tasks, or powering several modules in parallel. The built-in current limiting and thermal fuse protect against overload and prevent damage in the event of a short circuit.

It is suitable for applications where laboratory setups, measurement or test circuits need to be supplied with stabilized DC voltage continuously or for extended periods, such as a sensor array for room monitoring, a prototype alarm or counting system, or powering an embedded system in continuous operation. The device replaces external laboratory power supplies for low voltages.

On the input side, the device is connected directly to the electrical circuit; connections for the target circuit are available on the output side. The IP20 protection rating provides no protection against splashing water, so the power supply should be installed in a dry environment. Operation requires only a socket with a Schuko connection; no additional components are needed.

Safety information

This product is not intended for use in household electrical circuits or for permanent installation in power distribution boards. It is intended exclusively for building prototypes and for testing and development purposes. Work on or immediately next to the mains voltage side (230 V AC) must be carried out by qualified electricians; if there is any uncertainty about safe commissioning, consult a qualified electrician before starting.
