- Linear power supply unit provides a constant source of DC voltage and current for powering and testing electronic devices
- Two outputs supply adjustable voltage up to 30VDC and current up to 3 amp
- Third output supplies adjustable voltage from 0 to 5V or 5 to 10VDC and current from 0 to 3 or 0 to 1 amp, and fourth output supplies adjustable voltage from 0 to 5VDC and current from 0 to 1 amp
- Digitally controlled knobs for fine and coarse adjustment of voltage and current output
- 1mV/1mA resolution for observing the device under test's response to small changes in voltage and current
The Instek GPD-4303S quadruple-output programmable linear DC power supply unit provides a constant source of DC voltage and current for powering and testing electronic devices. The power supply unit (PSU) has two adjustable outputs that each provide DC voltage up to 30V and up to 3 amp. A third adjustable output provides voltage from 0 to 5V or 5 to 10VDC and current from 0 to 3 or 0 to 1 amp, and a fourth adjustable output provides voltage from 0 to 5VDC and current from 0 to 1 amp. Digitally controlled knobs on the unit's front panel allow for fine and coarse adjustment of the voltage and current output. The PSU has a resolution of 1mV (millivolt) or 1mA (milliamp), which allows the user to observe the device under test's response to small changes in voltage and current. Four LED screens show voltage and current readings for all outputs simultaneously. The outputs can operate independently, and the two 0 to 30V outputs can be connected in series to supply more voltage or in parallel to supply more current. A lock function disables the unit's front-panel keys to help prevent accidental input. The PSU's internal memory can store up to four sets of front-panel settings for future recall. The PSU has a USB port for connecting to a computer for remote control (USB cable sold separately). Software is included for testing applications and for emulating the PSU's front-panel controls. The unit's LED screens are readable in low light. A power cord with a three-prong plug is included for connecting the PSU to a grounded outlet, and test leads are included for testing applications. A built-in cooling fan helps prevent overheating, and overload protection and reverse polarity protection help prevent damage to the PSU and the device under test. For regulation and ripple and noise characteristics, see the unit's datasheet.
