Cincinnati, Ohio — Ferroresonant transformers from Foster Transformer provide a stable power output (typically &plusmn3%) for input voltages that vary as much as &plusmn15%. The standard square wave ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

A series of high efficiency, small footprint, off-the-shelf power transformers from Pulse for powered device side power over Ethernet products meet IEEE standard 802.3af. A series of high efficiency, ...

Maybe I'm describing a unicorn device here but I have a bunch of devices that run off DC-in of various voltages, and take a barrel jack connector for power. They all have their own wall warts but I've ...

Using a transformer coupled differential inverting amplifier stage can give a very low input referred noise voltage or Noise Figure (NF) with exceptional SFDR/mW. The NF equation needs to include ...
