The Siglent SPD3303C is a programmable DC power supply with three outputs. Two primary channels each deliver 0 to 32 V at 0 to 3.2 A, while a third channel provides selectable fixed rails of 2.5 V, 3.3 V, or 5.0 V at up to 3.2 A. Voltage and current on the main channels are set with 10 mV and 10 mA resolution and shown on dedicated LED meters.
A programmable DC power supply provides clean, regulated, and adjustable direct-current power to a device under test, with output values that can be set manually from the front panel or commanded remotely from a controller. Supplies of this type sit at the center of electronics development, production, and verification benches as the controlled power source for the circuit being evaluated.
ValueTronics supplies the SPD3303C from its own 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where we stock and hold our inventory in-house. Holding our own stock and verifying used equipment hands-on means buyers get accurate condition information and dependable availability on the instruments they need.
