Multiple Output Programmable Linear D.c. Power

Multiple Output Programmable Linear D.C. Power The GPD-3303S / GPD-3303D series inherits the superior technology and high quality, which GWInstek has established through its long history of power supply design and manufacturing. The GPD-3303S /GPD-3303D series provides 195W output power, three isolated output channels, high resolution output(GPD-3303S ), digital control panel, 4 sets of setup memory, USB remote control, smart cooling fan control, high reliability, and compact size. The GPD-3303S / GPD-3303D establish a new benchmark for economic programmable linear D.C. power supply market segment. The most remarkable feature of this series product with minimum 1mV / 1mA resolution of GPD-3303S, which right fits into the applications needing accurate control of power source.GPD-3303D, another member of the family, is considered a digitally-upgraded version of GPS-3303.FEATURES Three independent output: 30V/3A x 2, 2.5V/3.3V/5V/3A x 14 LED displays: 3 digits after decimal pointMinimum resolution: 1mV/1mADigital panel control (rotary encoder Switch, rubber key with indicator)User-friendly operation, coarse/fine volume control4 set save/recallKey-lockWarning buzzerOutput on/offTracking series and parallel modeSmart cooling fan achieving low noiseLight-weight and compact designUSB interfacePC softwareLabview driver SPECIFICATIONS DC OUTPUT CH1, CH2 CH3 Voltage 0~30V 2.5V/3.3V/5V Current 0~3A 3A Max.
