SPD constant current performance (current compliance protection)
January 3, 2019
The SIGLENT SPD series of power supplies offer constant current mode. This setting limits the current output of the specified channel and can be used as a constant current source and to protect your device-under-test (DUT). In this tip, we show the typical performance of the SPD as it switches between constant voltage (CV) and … Continued
SPD programming tips
December 26, 2018
The SPD series of power supplies feature remote programming capabilities and can be controlled via USB or LAN connection. In this note, we will use Python and PyVISA to create a program that will connect to an SPD, enable the output, delay, and then disable the output. There are two areas that differ from some … Continued

SPD3303-C Power Supply is stuck in Constant Current (CC) mode
November 9, 2018
The most common reason that the SPD3303-C is stuck in constant current mode (CC.. indicated by a red LED between the channel outputs) is an incorrect voltage setting on the inputs. Here is a picture of the voltage settings at 220 V, but with 120 V input power: Note that with no load attached, the … Continued

What is the difference between a switching and linear power supply?
October 24, 2017
Linear DC regulated power supplies (“linear supplies”) alter the output voltage to the required value through the power frequency (50/60 Hz alternating current) voltage transformer. After being lowered (or raised) to the appropriate AC voltage value, the waveform is rectified, filtered, and stabilized by a voltage regulation circuit, and is then output as a regulated … Continued
