- 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…
- DC-DC converter printed circuit board and input power considerations
DC-DC converters are relatively easy to use and, with a few precautions, will provide years of reliable operation. Most manufacturers will have instruction or application notes on…
- How do I operate the GXE600 programmable power supplies in Constant Voltage / Constant Current mode?
The GXE600 series of single output 600W programmable power supplies can operate in the shaded area of the diagram below. As an example, consider a constant current…
- What is the internal voltage drop in DRM40 DIN rail redundancy modules?
The DRM40 series of 20-40A DIN rail redundancy power modules use MOSFETs to block reverse currents for a low 200mV voltage drop. With a 40A load, the…
