Cincinnati, Ohio — Ferroresonant transformers from Foster Transformer provide a stable power output (typically ±3%) for input voltages that vary as much as ±15%. The standard square wave ...
A line of ferroresonant transformers offers a stable power output (±3% typ) for input voltages that may vary as much as 15%. Models are available for 50-, 60-, and 50/60-Hz frequencies, with output ...
An autotransformer is a transformer having part of its winding included in both the input and output circuit. A simple autotransformer connection is shown in Fig. 1. Note that because there is a ...
Smart transformers are designed to help better manage power for cities, and the largest smart transformer in the world apparently just went online.
Here’s a way of transmitting audio that makes it virtually impossible for someone else to listen in. Instead of sending radio waves bouncing all over creation, this uses the focused light of a laser ...
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 ...
