Non-reversible Â-ÒÏÅ and reversible Â-ÒÏÅ rectifiers of new generation have been developed and manufactured on full-scale. They are ideal to power electroplating bath with constant current. The rectifiers show their multipurpose use, as well as excellent technical data. The rectifiers have been designed on the base of state-of- art components, materials and advanced technologies.
Unlike previously manufactured rectifies, new ones provide for 100 per cent control of output current and voltage, in doing so, high accuracy of their stabilization is available.
The rectifiers may operate at other types of active load where high accuracy of stabilization of d.c. and direct voltage setting is required.
Thyristors, mounted on secondary side of converter transformer, control direct current.
Basic advantages of new rectifiers:
1. state-of art thyristors control system, that is built around microelectronics, is mounted on single printed circuit board . To increase the control system reliability the printed circuit board represents itself single-sided printed circuit board, its connection with external electric wiring is available by dint of connector ;
2. range of setting of current to be stabilized varies from 10 to 100 % of rated value as output voltage changes from 15 to 100 % of rated value;
3. range of settings of voltage to be stabilized varies from 15 to 100 % of rated value as output current changes from 10 to 100 % of rated value;
4. accuracy of output current or voltage stabilization is ± 2 %;
5. rectifier control by dint of external control desk is provided;
6. excellent power engineering values – efficiency and Cos ô;
7. automatic breaker installed at the rectifier input, shielding windings of transformer equipment , as well as built-in protection system against short-circuit currents and current overload provide for reliable and safety operation;
8. guarantee duration and service life is up to 10 years;
9. maintenance convenience. Access to all rectifier elements is available only on face side.
