Train Lighting Alternators
[attachment=37111]
Brushless Alternators for Self-generating Coaches are manufactured for supplying the power to the Train Lighting for the conventional Coaches and also electrical load for Air Conditioned Coaches.
The Alternators are presently being manufactured in capacities of 3 KW, 4.5 KW,18 KW and 25 KW both in 24 V and also 110 V DC.
Alternators are driven by Pulleys (Flat Belt/'V' Belt drive) which are also supplied as standard accessories along with Belt Tension Mechanism.
Electronic Recitifier cum Regulator Unit with Data Logger
The rectifier regulating equipment (RRU) along with alternators of 4.5 KW rating so far been used in conventional self generating coaches is based on magnetic amplifier with associated electronic control circuiting. The design of magnetic amplifier based (RRU) is having inherent limitations of voltage regulation.
The currently developed rectifier cum regulating equipment of 4.5kw rating (ERRU) is fully electronic type using state of the art technology and micro-controller, IGBT, etc having additional safety features viz. solid state over voltage protection, battery charging feature with current limit. A display can be retrieved in a simple plug in type data retrieval unit and the data can be transferred in a laptop or PC through USB port provided in the retrieval unit. No additional software is required when download is done in WINDOWS XP.
The universal voltage controller module (UVC) used in the 4.5kw ERRU can be used in ERRU of 25kw rating with alternators of 25kw rating where the operation parameters will be automatically selected.
