Silent laboratory power supplies by Manson

Silent laboratory power supplies by Manson
Multi-channel switched-mode power supplies by MANSON ensure a high comfort of use. They are fitted with a bright, easy-to-read display. Thanks to the convection cooling, they do not require a fan, which makes them remarkably silent. At the same time, the built-in series of protections (including thermal ones) significantly increases the safety of the power supplies themselves and the connected circuits. In addition, the power supplies have a STANDBY function - thanks to it you can disconnect the voltage at the output of the device, without the need to turn it off. The button responsible for this function is located at the front of the PSU, so you can use it easily and conveniently.

They are designed to take up as little space as possible on the worktop and are easy to move around: they are only 70mm wide, weigh only 2kg and have a semi-elastic handle on the enclosure. The front panel features dual-function knobs that allow rough and precise voltage and current selection.

Depending on the version of the power supply, the second and third channels are isolated and have banana sockets (NTP-5531) or USB sockets (NTP-5621).
