SIGLENT SPD3303X Series 3-Channel Adjustable Linear Programmable DC Regulated Power Supply

Introduction:
- SPD3303X/X-E series programmable linear DC power supply has a total power of 220W, with three high-precision power supplies independently controllable output, 5-digit voltage and 4-digit current display, and a minimum resolution of 1mV and 1mA. Strong and stable performance, able to accurately simulate even very small voltage or current changes, fully meeting the power supply requirements of the load.

Key Features:
- Total power 220W.
- Three-channel high-precision power supplies with independent controllable output.
- 5-digit voltage and 4-digit current display, with a minimum resolution of 1mV and 1mA.
- The design is compatible with 100V, 120V, 220V, and 230V.
- 4.3-inch TFT LCD display screen, 480x272 high-resolution.

SPD3303X/X-E has strong and stable performance, and can accurately simulate even very small voltage or current changes, fully meeting the power supply requirements of loads.
- Ultra high resolution: 1mV, 1mA.
- Excellent settings and read-back accuracy ensure precise and pure output.
- Support panel programming and timed output.
- Three high-precision power supplies with independent controllable output.

Convenient operation and real-time display:
- The panel timing output function (5 sets of timing settings and output control) can be achieved through panel operation. Meanwhile, in conjunction with the sophisticated upper computer software EasyPower, comprehensive communication and control requirements can be achieved.
- The SPD3303X/X-E programmable linear DC power supply is equipped with a 4.3-inch, 160000 color TFT-LCD display with a resolution of 480x272, which can display voltage and current, allowing users to have a clearer and real-time understanding of the output status.

Series/Parallel/Independent Mode Function:
- The series parallel function can merge two power sources into one power source for use, expanding the output power range of a single power source, which brings convenience in some application scenarios. The three independent power supplies can independently control the output switch, and can also be turned on or off simultaneously, making it very convenient to use.
