Siglent SPD3303X - Programmable Linear DC Power Supply with 1 mV/1 mA Resolution (3 Channels, 220W)

Programmable linear DC power supply
Three independently controlled and isolated outputs
Resolution: 1 mV, 1 mA
Display with 5 digit voltage and 4 digit current

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

High-resolution and high-precision output

The high resolution of 1mV/1mA (SPD3303X), provides excellent setting and read back accuracy. This ensures accurate output even with very with small changes in voltage or current. This is impossible for a low resolution power supply.

Series / parallel / independent mode function

Series and parallel function allows two channels to be combined into one output with more power output capability, extending the application range. Each of 3 channels power can be turned on or off independently, and also can be turned all on or all off.

Panel displays the timing output

Through front panel operation, 5 groups of timing settings and output control can be displayed, which provides users with a simple power programming function. A connection can also be made with Siglent’s EasyPower PC software providing a full range of communication and control features.

Save / recall setting parameters

The SPD3000X series can save or recall 5 groups of setting parameters in internal storage, and also supports external storage expansion. Settings can be easily recalled if needed

This is an easy to use 3 channel power supply with a lot of power! This supply is packed with features including an easy-to-read display, individual or grouped output switching, timer, fine adjustment and more. Honestly, the best supply in my lab!

I really like this power supply. It is very quiet and easy to use. Glad I purchased the Spd3303x version. The leads it came with are very good. The banana plugs fit perfectly. Highly recommend this DC power supply. TEquipment shipped the next day after I ordered the previous evening.

No good as a calibration reference

2.0

We were hoping to use these as a calibration source but they drift all over the place. We put it back in the box and haven't used it since. might be perfectly fine as a power supply which of course is what it is designed for just don't expect it to you a voltage to /- 1mV
