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.

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. ### ⭐⭐⭐⭐⭐ HP Variable Power Supply *by A***R on Reviewed in Canada on 9 July 2024* A Good HP Product, ### ⭐⭐⭐⭐⭐ Alimentation de labo *by P***T on Reviewed in France on 9 November 2024* Indispensable dans mon labo, pratique de de bonne qualitΓ© . ## Frequently Bought Together - Siglent Technologies SPD3303C DC Power Supply - Sumnacon Multimeter Banana Plug to Crocodile Alligator Clip Test Probe, 5PCS 4mm Stackable Colorful Silicone Banana Plug to Alligator Clip Test Probe Lead Wire Cable 1M - Sumnacon 39 Inch Multimeter Test Lead Set - 5 Pcs Stackable Banana Plug to Test Hook Wire Cable Kit with Protective, Flexible Wire Leads for Electrical Testing 500V/5A --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/117915575-siglent-technologies-spd3303c-dc-power-supply](https://www.desertcart.co.uk/products/117915575-siglent-technologies-spd3303c-dc-power-supply) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
