These are cost effective remote programming power supplies with lab graded performance. They are ideal for laboratory , university , work shop , production , quality control and advanced DIY . Computer interface via USB for cyclical operation , plus wired analogue remote control makethese power supplies open up many demanding applications. Fine and Coarse tuning with definitive rotary encoder volumeknob and open circuit CC setting are really user friendly.

This range of high graded SMPS is designed for a wide range of applications for telecommunications, laboratory andindustry. The power efficient circuit designs allow units tohave small form factor with low profile and small footprint casings. The intelligent fan speed control program checks the fan at power on and adapts the right speed to ensure a quiet and safe operation of the power supply at different ambient temperatures and power output levels. The dual action (coarse & fine set) control knobs make tuning the voltage and current level ever so smooth, precise and fast, due to the rotary encoder and microprocessor control. Setting the CC current limiting can be done in open circuit at output poles. The isolated ground construction allow parallel and series connection of power supplies with ease and safety. The three user defined presets of voltage and current limiting levels facilitate quick access to frequently used VI settings. Analogue remote control functionality offer a wide range of operation possibilities for the industrial and more sophisticated users. We add an USB port for access to computer to run cyclical operation with programmable voltage, current, period time and cycles.
