2. GENERAL DESCRIPTION
These units are works by a full wave accurate
controlled thyristor and lnductive filters and
smoothing capacitors to reduce the ripple amplitude
of output. Thyristor regulation ensures low power
dissipation and generously specified components
provide for high operation efficiency.
