Customization Process for Energy-Saving DC Power Supply Units
Select switching devices like MOSFETs or IGBTs with low RDS (on) and fast switching times. Use inductors and transformers with high saturation current and low hysteresis losses. , LLC resonant, synchronous rectification, GaN/SiC) can achieve peak efficiencies in the 90–95% range in optimized designs, depending on operating conditions and system constraints. And provisioning power for a product involves several choices, the first of which is whether to buy a ready-built power supply or to design a discrete unit. Creating a power supply from scratch might appear an attractive option if your product or application has particular needs. In this article, you will learn how different components affect system accuracy, and how to choose suitable components for a precision DC power-supply design.

High-density DC power supply unit 1U available now
The 1U family of programmable AC-DC power supplies sets a new standard for flexible and reliable power for your application. Available in a Rack Mounting or Benchtop at 720W power levels with single output voltages ranging from 3. By combining a compact mechanical form factor with modern power-conversion and control technologies, 1U rack-mount DC power supplies enable high power density without the footprint associated with traditional large-format instruments. Our rack mount power supplies deliver reliable, programmable DC power in a compact form factor that fits directly into standard 19" racks—making them ideal for ATE systems, production lines, and high-density test environments. With power ratings from 400 to 1800 W, they offer up to 12 isolated outputs with DC output from 0. Columbus, Ohio [March 18, 2025]– Vertiv (NYSE: VRT), a global provider of critical digital infrastructure and continuity solutions, today announced the.

Adding an optical attenuator
Optical attenuators are commonly used in, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels.

What is the working principle of an adjustable mechanical optical attenuator
The working principle of MEMS VOA is based on the mechanical movement of the micro-mirror or micro-shutter. An optical attenuator is a passive optical device that has a function opposite to that of an optical amplifier. The attenuator circuit will allow a known source of power to be reduced by a predetermined factor, which is usually expressed as decibels. New for June 2019: mechanically variable attenuators are often used in lab equipment, so that one unit can serve many purposes (instead of a drawer full of fixed attenuators). They are continuously adjustable (using a thumb wheel or a screw head for examples), and consume zero DC power.
