NIKSA - Microprocessor controlled Rectifier / Battery Charger
NIKSA microprocessor controlled Rectifier/ Battery Charger is designed to supply DC
A mere split second of interrupted power could spell disaster for customer and industries whose operation depends on constant power supply. Based on years of experiences, NIKSA has a range of chargers that provide practical and economical solutions to meet the vital requirements.
power to sensitive equipment at a constant uninterruptible voltage, free from the usual utility power line distributions. Rectifier consists of input isolating transformer, fully controlled thyristor set, filtering circuit, control and monitoring unit which can supply power to batteries and load simultaneously. The system output characteristic provide a constant current and constant voltage charging curve to eliminate the possibility of overcharging of the battery connect in parallel with the system even with the incoming variation. A number of functions for digital controlled rectifier is built in as based model. Most desires the system software is developed and written in high level language therefore further feature can be easily added to your needs as option and it user friendly to control and monitor all the function.

System Configuration
Depending on the project specification, voltage tolerance, load and safety requirements, various configuration might be selected to cope with customers’ requirements.
System with Off-Load Switch
System with Boost Interlocking Facility
This parallel redundant system provides 100% standby power if rectifier and batteries are designed for the full load. Two sections, each with one rectifier and one battery bank, are connected to a common bus bar and can operate independently or in parallel. With the boost charge can take place in one section, when isolated from the load with a switch. At the same time, the other section will be on floating charge and supplying to the load.
A parallel system consists of two rectifiers and batteries rated at 100%. Under the normal condition, the two rectifiers share load current and charges the respective battery. With the boost interlocking circuitry, batteries will automatically boost charge, take place from one after the other. The interlocking device precludes both rectifiers set to boost at the same time.
System with dropping diode device
Hot Standby System
Rectifier connected to the load side, consists of a number of diode groups, which are switched in or out of the circuit by a voltage sensing control.
The DC system comes with two rectifiers and one battery. One designated as “ Main” and the other as “Standby”. The standby rectifier is always ready to back up if the main rectifier fails. The Automatic Switching Device will transfer the dc supply of the standby unit to the failed rectifier without interruption to the load.
The diode groups are made up of series-connected silicon diodes, keeping the output voltage within the specified tolerance. The electronic control unit of the dropping diode device is a stand-alone unit.
