Description

Instek GPS-4303 - 200W, 4-Channel, Linear D.C. Power Supply

The Instek GPS-4303 is an affordable high quality 4 output DC power supply. Having 4 outputs meets the increasing industry need for multiple output sources in testing and development. The blend of high accuracy, safety features, application flexibility, compact design and affordability makes the GPS-4303 the perfect power supply for nearly any user.

Steady & Clean Power
The GPS-4303 features an impressive 0.01% load and line regulation. Ripple & Noise comes in at just < 1mVrms , 5Hz ~ 1MHz under constant voltage operation. The output load is protected from accidental damage during changes through the use of the convenient on/off switch located on the front panel.

Flexible Output Range
The GPS-4303 provides users with a flexible solution to meet job requirements and still remain under budget. In addition to the tracking and auto Series/Parallel features, extend your application range up to a 60V/3A by series and 60V/3A by parallel without need to purchase another power supply.

Low Fan Noise
Instek has developed this power supply to be suitable for any application. In order to eliminate unnecessary fan noise, the GPS-4303 will automatically lower the fan speed under low or no load condition. This makes it appropriate for laboratory use.

Large Front Panel Display
The large front panel display on the GPS-4303 allows for two outputs (including both voltage and current) to be monitored concurrently

Great Supply

5.0

Wonderful and very versatile supply for the money. 4-channels plus the ability to put 2 in series for up to 60V means you can pretty much develop any application for embedded or telecom electronics. Key piece of equipment on my bench.

Best Benchtop Supply for the Money

5.0

I have purchased about 7 of these power supplies for my company and am happy with everyone. We have been using them daily for over five years without any problems. One of the best features is the current limiting adjustment. It makes it possible for the two main channels to work as a current source as well as a voltage source. The dual display (current and voltage) is awesome.
Highly recommend!

We are changing over all our 14 tech to the INSTEK GPS-4303 we all love them. The 4 channel design is very versatile. Some of our tech still had Heath Kit single channel supplies. They are in Heaven

Great device for the price

4.0

As the title says, it's a great piece of equipment for the price. The only reason it did not get 5 stars is because the knobs are a bit too touchy, and the channel selection switches are a bit confusing at first.

This is a nice power supply. The four outputs come in handy for my small hobbyist projects. CC/CV modes, what more could I ask for? Well worth the money and great customer service.
