UPS

TEC-products-UK-banner-CVT-770px TECCVT-small manufacture and supply a range of CVTs to a number of customers for incorporation in their own equipment.

Our CVTs are solidly built units with no moving parts or electronic components except one or more resonating capacitors (CVTs can be supplied with or without capacitors). This makes the CVT almost indestructible. The output can be continuously and completely short circuited without damage

The CVT will provide a regulated voltage output on a cycle to cycle basis whilst being unaffected by either low or high input voltage. The CVT will present a low impedance to very high voltage surges and provide an effective barrier to lower energy spikes which can cause data corruption in computers and computer-based equipment.

Although normally specified over a ±15% input range, the CVT does not stop working outside this range, however for practical reasons a swing in excess of ±25% ceases to give a useful output. Because of the resonating circuit in the output of the CVT, a limited energy storage capability is exhibited which will maintain the output for a period approximating  half a cycle if the input is temporarily interrupted.

TEC CVTs are manufactured using class F materials as a minimum. In addition to normal testing each CVT is checked for insulation integrity by "flashing" the input and output windings to core and earth.

UK Established Since 1918

The Claude Lyons Group was founded in the UK in 1918 and is still in private ownership. Since our early days we have been innovators in areas related to voltage and power control and more recently in energy saving and harmonic mitigation. Operating as a global exporter with many years experience we can justifiably call ourselves a world leader in the field of voltage stabilisers, power conditioning and uninterruptible power supplies (UPS)
