Triple output

The EST150 combines three power supplies into one housing. The power is characterized by its lifetime and stability. Multiple power supplies can be connected in series, parallel, or both in series and parallel to create numerous output configurations. Due to its small size and triple output, the unit is extremely suitable as a bench top power supply.


High isolation voltage

The output terminals are floating and isolated up to 600 V DC. This allows powering several circuits at different voltage potentials from only one device!
