Description

The Instek GPS regulated DC power supply series is designed to be used in applications such as powering operational amplifier, push-pull stages, logic circuit and definition systems where plus and minus voltages are required to track with an insignificant error. To represent an operation convenience, GPS-4302, GPS-4303 and GPS-4251 have four independent power supplies (while GPS-2303 has two and GPS-3303 has three) housed in a single package.

GPS-4302, GPS-4303 and GPS-4251 consist of four identical, independent, adjustable DC power supplies (while two for GPS-2303 and three for GPS-3303). A front panel switch selects one of three operation modes of independent, series and parallel. In the independent mode, the output voltage and current of each supply are controlled separately, and each supply is isolated up to 300V from output to chassis or output to output. In the tracking mode, both outputs are automatically connected in series or parallel, and the controls of the left supply adjust the magnitudes of both the positive and negative output voltages. Because the outputs are connected in a tracking configuration, any internal disturbance in the master supply (such as drift or ripple) will cause an equal percentage change in the outputs of both the supplies.

Each power supply (except CH3 for GPS-3303 and CH4 for GPS-4302, GPS-4303, and GPS-4251) is a completely transistorized, well-regulated, constant voltage/constant current supply that will provide full rated output voltage at the maximum output current or can be continuously adjusted throughout the output range. The front panel current controls can be used to establish the output current limit (overload or short circuit) when the supply is used as a constant voltage source (independent or tracking modes) and the voltage controls can be used to establish the voltage limit (ceiling) when the supply is used as a constant current source (independent mode only). The supply will automatically cross over from constant voltage to constant current operation (current limited operation in the tracking mode). Each power supply (CH1~CH4) has its own front panel meter that can measure output voltage or current. One power supply may be used as a CH1 supply controlling, one CH2 supplies furnishing various voltage or current for a system. When operate with the front panel mode switch in the tracking position, the instrument is automatically internally connected in auto-tracking configuration.

For audio production line, the continuous or dynamic load can be internally selected. When the connector (J111 & J309) is connected to "ON" position the unit is suitable for audio power Amplifier application (Normal setting to "OFF" position).

InstraView™ Equipment Inspection



Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
