The PSW series devices are multi-range laboratory power supplies with a single output. The multi-range function allows for quick and flexible adjustment of output voltage and current within the device's output power. Up to three power supplies can be connected in parallel and up to two units in series. Additionally, devices from the PSW series with different output values can be combined. This creates a variety of combination options, providing the right solution for many applications. By default, the PSW series devices are equipped with a USB and LAN interface.
