Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
The GPS series is a single output, 54W~90W linear DC power supply. Overload protection, reverse polarity protection function, low variation rate of 0.01% and <1mVrms low ripple/noise are the distinguishing features of the GPS series. Continuous or dynamic internal load selection function is suitable for applications such as pulsed current.
