SK3323/3325/3503 Sk3323 Power Supply programmable linear DC power
Feature
The SK33XX series programmable linear DC power supplies have three independent outputs – two sets of adjustable voltage/current and a fixed set of selectable voltage1.8V, 2.5V, 3.3V and 5V. it has three available operation modes–independent, series and parallel modes. All make this series become a high performance-to-price ratio instrument.
Aplication
Military R&D, Quality detection, Circuit test, Test of industrial manufacture automatization,
Education and Technical Training, Test of electronic assemblies, Aging test
Design Feature
1. 3 independent outputs-two 32V or 50V /5.1A or 3.2A, one 1.8V, 2.5V, 3.3V, 5V/3.2A, maximum 342W.
2. 4 digit voltage and current display, minimum resolution-10mV, 1mA
3. Smart temperature controlled fan to reduce noise effectively.
4. Save/Recall 5 group system set-ups
5. Standard timing output
6. Comprehensive over-voltage protection
