Siglent’s SPD3000X Series Programmable Linear DC Power Supply has a 4.3 inch TFT-LCD display, supports Remote Programming and has a Real Time Wave Display. The ‘3000X family has three isolated outputs; two adjustable channels and one selectable channel from 2.5v, 3.3V, and 5V. It also has output short and overload protection and can be used in production and development.

Features Siglent SPD3303X / X-E Series Programmable DC Power Supply :

• 3 independently controlled and isolated outputs: Two 32 V/3.2 A, one 2.5 V / 3.3 V / 5 V / 3.2 A × 1, total 220 W
• 5 digit Voltage/4 digit Current Display, Minimum Resolution: 1 mV/1 mA (SPD3303X)
• Timing function provides programmed output steps
• 4.3 inch true color TFT- LCD 480 x 272 display
• 3 types of output modes: independent, series (60 V max), and parallel (6.4 A max)

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.
