GW-INSTEK GPS-4303
The GW-INSTEK GPS-4303 is a 4-channel linear DC laboratory power supply for benchtop use. It is used when multiple stable voltages are needed from the same unit, for example, in the development, testing, and troubleshooting of electronic circuits. Two of the channels can be adjusted from 0 to 30 V and 0 to 3 A each, while the other two channels provide fixed low-voltage outputs of 2.2 to 5.2 V and 8 to 15 V, respectively, with up to 1 A.
What is special about the GPS-4303 is that channels 1 and 2 can be used together in tracking. They can be connected in series up to 0-60 V or in parallel up to 0-6 A. This makes it easier to work with both higher voltage and higher current without needing separate power supplies.
As a linear power supply, it is well-suited when a stable output with low ripple and noise is desired. For channels 1 and 2, line regulation is stated as ≤0.01% + 3 mV, and ripple & noise is ≤1 mVrms. These are relevant figures in a laboratory where small variations can impact measurement results and test runs.
The front is designed for practical use at the workbench, and the unit measures 255 × 145 × 265 mm with a weight of approximately 7 kg. It is powered by AC 100V/120V/220V ±10% or 230V (+10% to -6%), 50/60 Hz.
Typical Applications
The GPS-4303 is typically used in electronics production, development departments, service, and test environments where multiple DC voltages are needed for the same setup.
