Excellent output performance
The SPD3303X/X-E is a powerful and stable performer, capable of accurately simulating even very small voltage or current variations, and fully meeting the power supply requirements of the load.
- Ultra-high resolution: 1 mV, 1 mA
- Excellent setup and readback accuracy to ensure precise and pure outputs
- Supports panel programming and timed outputs
- Three high-precision power supply independent controllable outputs
- Excellent setup and readback accuracy to ensure precise and pure outputs
- Supports panel programming and timed outputs
- Three high-precision power supply independent controllable outputs
Convenient operation and real-time display
- Panel timing output function (5 sets of timing setting and output control) can be realized through panel operation. At the same time, in conjunction with the comprehensive host computer software EasyPower, comprehensive communication and control requirements can be realized.
- SPD3303X/X-E programmable linear DC power supply is equipped with a 4.3-inch, 160,000-color TFT-LCD LCD with a resolution of 480 x 272, which displays voltage and current, allowing users to have a clearer, real-time understanding of the output status.

Series/Parallel/Independent mode function
The series-parallel function can combine two power supplies into one power supply, expanding the output power range of a single power supply, which brings convenience in some applications. Each of the three independent power supplies can be individually controlled to switch the output on and off at the same time, which is very convenient to use.
