PSM3 series is a multi-channel Linear DC power supply with 3- output channels. Its high stability and enhanced linearity make this regulated DC power supply significantly useful where high performance and stable power sources are required. It is widely adopted for R&D, educational and industrial usage.
It provides full load stable performance, intelligent ventilation fan control to minimise operation noise, and fully adjusts voltage and current readings. When output overloads, the system will automatically cut off the output to protect the connected circuit or loading. At the same time, the overload indicator will illuminate to warn the operator for further action.
In auto-tracking mode, the PSM3 series can auto-connect CH1 and CH2 output either in parallel or in series internally to provide double current or voltage output.
On-screen 3 sets of the output display. Operator not required to switch display, direct monitor all channel’s voltage and current usage status simultaneously.
These excellent performances with extract stability and enhanced linearity make the unit very outstanding. These power supplies are suitable for laboratory, university, high school, and workplace uses or where high performance and precision regulated DC power supply is required.
