Nova geração de Retificadores Trifásicos Digitais - RTD com dupla conversão de energia, unidade conversora de queda e controle totalmente digital microprocessado. Esta nova tecnologia oferece segurança, eficiência energética, facilidades na operação e no gerenciamento remoto.
A Unidade Conversora de Queda - UCQ, é uma grande inovação nesta aplicação, substituindo os inefcientes diodos de queda (UDQ) por um conversor chaveado em alta frequência com modulação PWM, que mantém a tensão do consumidor perfeitamente estabilizada.
Effective safety and control
Designed to provide safety, energy efficiency, easy operation and remote management, the Digital Rectifier with Microprocessor features double energy conversion, drop converting unit and totally digital control with microprocessor. The drop converting unit replaces the dropping diodes through a robust switchable converter at high frequency with PWM modulation, which keeps the consumer's voltage perfectly stabilized, thus ensuring a longer service life of the load components.
Applications
Electric substations, emergency light systems, industries, laboratories, hospitals, off-shore and military projects, special projects with redundancy and DC-supplied systems.
Main characteristics
- LCD panel for electrical measurements and operations, integrated into an alarm system with LED and remote indication
- Operation diagnosis by means of the event log system with date and time
- Five time faster in dynamic voltage regulation for load steps from 10% to 100%
- Fewer connections with quick-connect reversing-proof connectors
- Models available at 220 V, 380 V, 440 V, 480 V and 690 V
- Internal protections in polycarbonate that allows visual inspections and increases the operator’s safety (NR 10)
- Auxiliary service plug socket with automatic internal light
- Battery charging system with thermal compensation and external temperature sensor
- Dehumidification system with control by thermostat and protection circuit breaker
- Remote isolated Modbus-RTU RS485 and local USB communication interfaces, with PC standard software application for configuration, tests and diagnosis
- Manual bypass system which allows replacing all the boards without interrupting the power supply to the consumers.
