GW Instek GPS-4303 Bench Power Supply, DC, Linear, 4 Output, 0V, 30V, 0A, 3A

The GPS-4303 CAL from GW Instek is a GPS-x303 series, 200W, 4-channel linear DC power supply. Overload, reverse polarity protection and an output on/off switch keep the power supply and its load safe from unexpected conditions. A high regulation (0.01%+3mV), low fan acoustic noise and low ripple/noise (< 1mVrms, 5Hz to 1MHz) are maintained for channel 1 and 2 in constant voltage mode. Automated cooling fan speed control minimizes fan noise according to load conditions ensuring quiet operation. It is an ideal solution for lightweight, inexpensive benchtop or portable applications requiring high regulation & multiple outputs. It has <= 0.5% + 10mV of CH1 tracking error, <= 0.01% + 5mV series regulation, <= 300mV load regulation, <= 2mVrms, 5Hz to 1MHz ripple & noise during tracking operation. The GPS-4303 has insulation resistance of 20Mohm (>= DC 500V/chassis and terminal) and 30Mohm ((>= DC 500V/chassis & AC cord). It has <=15mV (CH3), <= 10mV (CH4) load regulation & 1A (CH4) output current.
