The Siglent SPD3303X-E bench power supply is a programmable linear DC power supply, designed to deliver precision and flexibility in professional and electronics development environments.
This model features a 4.3-inch colour TFT LCD display that lets you view waveforms and output parameters in real time, making control and monitoring easier.
Key features
- Three independent and isolated outputs: two adjustable channels of 0-32V and 0-3.2A, and one fixed channel selectable between 2.5V, 3.3V or 5V with 3.2A.
- Maximum total power of 220W to cover a wide range of power needs.
- Resolution and accuracy: 5 digits for voltage, 4 digits for current, with minimum resolution of 1mV and 1mA. Voltage accuracy ±(0,03% reading + 10mV) and current accuracy ±(0,3% reading + 10mA).
- Output modes: independent, series and parallel, allowing channels to be combined for greater power or voltage.
- Built-in protection: against short circuits and overloads to help ensure equipment and user safety.
- Fan with intelligent temperature control to minimise operating noise.
- Parameter storage: capacity to save and recall up to 5 groups of internal settings, with support for external expansion.
- Connectivity and software: includes EasyPower PC software, compatible with SCPI and LabVIEW driver for integration into automated test systems.

Customer Questions & Answers
What is included in the box, and what are the exact dimensions of the unit?
The box includes the SPD3303X-E power supply, a mains cable, two sets of test leads (banana to crocodile clip), a USB cable, CD with software and the manual. The approximate dimensions of the unit are 245 mm × 158 mm × 315 mm and the weight is around 7.0 kg.
What are the main limitations for continuous use regarding overload, ventilation or accuracy?
The unit has overcurrent and overload protection; however, it must always be operated within the maximum specifications: up to 32 V and 3.2 A per adjustable channel, with a combined total power of 220 W. The intelligent fan regulates temperature, but it is important not to block the ventilation grilles. Typical output accuracy: ±0.03% +10 mV for voltage and ±0.3% + 10 mA for current.
Does this power supply comply with safety standards, and what type of warranty does the manufacturer offer?
The SPD3303X-E complies with international electrical safety standards (IEC61010) and electromagnetic compatibility requirements. It offers a standard 3-year warranty under normal use conditions, covering manufacturing defects. After-sales support includes spare parts and calibration through authorised distributors.
What type of outputs does the Siglent SPD3303X-E power supply have?
It has three independent outputs: two adjustable channels of 0-32V and 0-3.2A, and one fixed channel selectable between 2.5V, 3.3V or 5V with 3.2A.
