TEC manufactures
and supplies a range of CVTs to a number of customers for incorporation in their own
equipment.The 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 to itself.
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 a 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.
