Power Supply Basics (page 2)
- How do non-isolated buck, boost, and buck-boost converters differ?
Non-isolated buck, boost and buck-boost topologies are utilised in the designs of many AC-DC power supplies and non-isolated DC-DC converters. Although many of the patents were filed…
- How can DRM40 DIN rail redundancy modules be used?
Having redundant power supplies helps reduce equipment down-time. In the event a power supply fails, the remaining unit will continue to power the load. A faulty power…
- What functions can I read and write using the GXE600 programmable power supply’s communications interface?
The output voltage and current can be programmed over a wide range on the GXE600 series of single output 600W programmable power supplies – 20% to 100%…
- What is the difference between DRM40 and DRM40B DIN rail redundancy modules?
The DRM40 series of 20-40A DIN rail redundancy power modules is equipped with a current balance function, two DC OK LEDs and two isolated DC OK photo…
- How can I program the voltage and current for GXE600 programmable power supplies?
The RS-485 interface on the GXE600 series of 600W programmable AC-DC power supplies can be used to programme the desired voltage and maximum current with commands or…
- How do I use the DRM40 DIN rail redundancy modules current balance feature?
For optimum longevity, each power supply connected in redundancy should deliver the same amount of current. If power supply “A” delivers 75% of the load and power…
- How can DRM40 DIN rail redundancy modules be used?
Having redundant power supplies helps reduce equipment down-time. In the event a power supply fails, the remaining unit will continue to power the load. A faulty power…
- What is the communications interface for the GXE600 and how would it be used?
A typical application for the GXE600 series of 600W programmable power supplies would be in an automated, connected manufacturing facility – either as a programmable power source…
- Do DRM40 DIN rail redundancy modules have safety certifications?
The DRM40 DIN rail redundancy power module is certified to IEC 60950-1 and IEC 62368-1 (EN/UL/CSA) safety standards. It has also been certified to UL508 and Canadian…
- How to ensure reliable operation of DC-DC converters (cooling and derating)
Today’s manufacturing techniques have improved DC-DC reliability considerably. The use of surface-mount placement for 100% of the components, computerised optical inspection of solder joints, automated test and…
