Reliability through Excellent Design

The outstanding reliability of the BDTe is ensured by a combination of high-end technology and robust design. In detail, the advantages are based on:

• Leading microprocessor-controlled thyristor technology
• Internal power supply with 5 independent DC converters including health monitoring
• Integrated watchdog circuits
• RS485 daisy chain internal communication bus
• The unique feature of ultra-cap real-time clock
• (RTC) back-up with time synchronisation facility
• Dedicated I/O board with numerous configurable analogue and digital inputs
• CAN bus for parallel operation for robust digital communication
• 12-puls operation with active load sharing (option)
• Advanced filter- and PID control scheme for best diesel generator compliance
• The unique feature of fully segregated, independent and redundant measuring facility (shunt and/or CT) including mains power meter
• Independent microprocessor-based diode voltage dropper (DVR) controller
• On-board earth fault monitor with leakage current indication
• PT1000 based real-time temperature display and monitoring

Easy Operation & Control

The front panel of the BDTe facilitates a comprehensive and flexible human-machine interface. An easy and intuitive operation and control of the system is achieved through:

• Colour coded and animated LED mimic flow diagram adapted to the actual configuration
• Comprehensive 8-line LCD display
• Multi-language support
• 12 Programmable alarms and indications
• Intelligent real-time event recorder for 2500 events
• Continuous battery availability (health) check
• Multi-level user management
• Front access to key components (fans, capacitors, ) to allow fast and cost-effective maintenance

Easy Accessible Interface & Intuitive Communication

State of the art communication software and gateway supports the monitoring and control of the BDTe. Fast and easy accessibility and intuitive communication are achieved through:

• RS232/RS485 serial interface with MODBUS protocol
• Modbus TCP/IP interface
• PROFIBUS interface
• IEC61850 interface
• TCP/IP network interface with onboard web-server
• USB-stick interface for event-log and configuration dump (readout)
• Remote display
• Programmable relays cards
• Digital inputs (for EPO, generator operation etc.)
• Programmable analogue inputs (battery temperature, etc.) with clear text messages

Reliable Battery Use and Management

Battery monitoring and management is a key factor for a reliable and durable power backup. The Statron BDTe has class-leading built-in features, such as:

• Multi string battery current monitoring
