Excellent Output Performance
The SPD3303X/X-E is robust and stable, and can accurately simulate even small voltage or current changes, fully meeting the power requirements of the load.
· Ultra-high resolution: 1 mV, 1 mA· Excellent setting and readback accuracy to ensure accurate and pure output
· Support panel programming and timing output
· 3 independently controlled and isolated outputs
Convenient Operation and Real-time Display
- Support panel timing output function (5 sets of timing settings and output control). With Free PC software EasyPower, comprehensive communication and control requirements can be easily achieved.
- The SPD3303X/X-E programmable linear DC power supply employs a 4.3-inch, 160,000-color TFT-LCD liquid crystal screen with a resolution of 480×272 which can display voltage and current clearly, allowing users to understand the output status.
Series/Parallel/Independent Mode
The series-parallel function combines two power supplies into one power supply, which expands the output power range of a single power supply, which brings convenience in some applications. The three independent power supplies can individually control the output switch, and they can be turned on or off at the same time.
