Product information
Details
PSM series is a high performance and precision Multi channels DC regulatedpower supply up to 4-channel outputs. This PSM series has constant voltagemode(CV), constant current mode(CC), auto current cut off protection function,overload protection and auto tracking mode. In auto tracking mode, PSMseries can auto connect CH1 and CH2 output either in parallel or in seriesinternally to provide double current or voltage output.
PSM4 series can provide 4 channels adjustable outputs while PSM3 seriesprovides 2 channels adjustable output and one fixed 5V/1A output. The PSM2series provides 2 channels adjustable output. All adjustable voltage andcurrent output values can be linearly adjusted.
With the extra stability and enhanced reliability, this PSM series Multi channelspower supply is suitable for bench, laboratory, university, high school, andindustrial use or where a high performance and precision regulated DC powersupply is needed.
Features:
- 2 Adjustable Channels Output (PSM 2 Series)
