The Integrated System-Design approach has made it possible lor produce Righill to Dedicated type Electronic Controls for a variety ot applications. Employing Innovative electronic circuit designs, combined with in-depth understanding of performance operational and requirements, Righill have synlhesized all the Control & Protection Electronics variations into single Electronic Control Modulescoveringa vast range of applications The Electronic Controls therelore nothaveto be do conceptualised afresh with a multiplicity cards in each case, of which also eliminates chances anv ot systemdefficiencies. Other advantages are economy, higherreliability since ---there is much less electronic hardware costor fail,coupled to with simplicity to absence a maze due of of PCBs thus avoiding speciatised deciphering.

B ighill eq u i p m e n t is characterised one of the most by compact yet spacious - for maintenance designsavailablein the world. Also, the compacl make it feasible for electronics Flighillto readilyproduceequipm ent in required sizes for fitting into applicationswhere space is at a premium, e.g. mobile machinery, locos, etc. StandardRighillPanelswhich contain all LT switch-gear, Electronics Metering 500-mm & are wi d ex 1800 mhig hfe su p to1 .2M W m 4 1 5- VP ower Cont ro l s ,&4 0 0 Amo . 750 V DC Drive Convertors.
