## Questions & Answers

**Q: What are the actual dimensions of the power supply?**
A: Dimensions of the Siglent SPD3303C - from our website:
275×225×136 mm

**Q: I want to control this from my own windows program.  does it enumerate as a com port that i can send and receive text commands? i don't use labview.**
A: Yes, and it takes standard SCPI commands. Works great for this, I’ve been controlling mine with Python/PySerial.

**Q: Can the outputs be connected in series to produce higher voltages?**
A: Yes, in series mode, it can output 60 volts, but not 64 v as you might expect, which would be twice the 32 v that it outputs in independent or parallel mode.  I don't know why it limits to 60 volts in series mode, but it will output 60 v at 3.2 amps

**Q: Can this bench power supply negative voltages?**
A: The SPD3303C is an FLOATING unipolar power supply - like a battery.   The red terminal is always more positive than the black terminal.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good solid PSU
  

*by A***E on Reviewed in the United Kingdom on 24 August 2020*

I have had this PSU for a couple of years, it is used daily and has performed flawlessly.  It is well built and provides a good stable output suitable for general bench usage. Support from Siglent is very good, I managed to break one of the terminal posts off recently which Siglent replaced for me FOC.  I have every confidence in this PSU and would not hesitate to recommend it to anyone as a general purpose benchtop supply.
