4 Output DC 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.

 

Customer Feedback

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! Best benchtop power supply for the money!!

Overview

 
 

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.
