Voltex

Voltex Inc. of Colorado Springs, formerly Plasmatronics before our move from California, has been growing stronger over the last few years, and in the last several years has developed several models that effectively leave our competitors behind. We are now arguably the leaders in the HeNe power supply world. Starting in 1991 with the new technology... contained in the "R" and the "U" models, we began to surge ahead of the others. These two models contain technology which is unmatched in the industry. With an output having a dynamic range of at least 25:1, nothing else even comes close to the capabilities of these models. Our U, or Universal Test Station, is now in service at several of the HeNe laser manufacturers, where they are used all the time and are very popular, to say the least. In 1993, we solved the two fundamental problems which have plagued the 240 Volt input, or dual AC input supplies. We first learned of these perplexing problems several years ago when, for a short time, we made a small family of 240 - V input types. The problems that emerged were: (1) Just occasionally, on startup, a supply would instantly and inexplicably fail. (2) This problem, with competitors' units and not with ours, was a troubling one: - Just occasionally, a supply would violently explode, sometimes with disturbing and expensive results. We wanted to make very sure that these problems were well understood and dealt with thoroughly before we went to market with a dual-input supply. In 1993, we went to work on these phenomena and came to understand their causes. This work allowed us to design in circuitry which has effectively eliminated both of these problems. The first problem is caused primarily by the limited capabilities of the switch transistors available today. During the first millisecond or so of operation, the switch is exposed to stresses which it should not be asked to deal with. We have designed "soft start" circuitry which firmly controls the switch through the start - up period, until in full operation, ...Read More
