Product catalog summary

Technical Specifications
The SDC Rectifier/Battery Charger operates with input voltages of 3x380/400/415V and tolerates a DC input voltage variation of +/-10%. It functions within a frequency range of 50/60 Hz with a tolerance of +/-8%. The power factor varies with line power and float voltage, ranging from 0.75 to 0.90. Output voltages are available at 24, 48, 110, 125, and 220 VDC, with a setting range for float and boost voltages. The DC voltage tolerance is +/-1%, and the system can handle dynamic load changes with a regulation time of less than 100 ms.

Performance and Efficiency
The rectifier achieves up to 94% efficiency depending on the type. It features a DC overcurrent capability of 150% for 2 seconds and maintains a DC ripple voltage of ≤2% rms with a parallel battery. The system is designed to operate in ambient temperatures from -10 to +40 °C and at altitudes up to 1000 m.

Standards and Safety
The SDC Rectifier complies with safety standards IEC/EN 62040-1-2, EMC standards IEC 62040-2, EN 50091-2, and performance standards IEC/EN 62040-3, IEC 60146-1-1. It carries a CE label for conformity.

System Configuration and Options
The standard configuration includes a 6-pulse rectifier with an isolation transformer, an LCD display unit with a keyboard, and various input/output connections for alarms and remote operations. Optional features include parallel redundant configurations, additional ripple filters, 12-pulse rectifiers, and advanced battery monitoring systems. The system supports RS-232 and RS-485 interfaces for communication and monitoring.

Human-Machine Interface
The front panel provides a comprehensive interface with operational parameters, selectable display languages, and charge modes. It includes an LC display, alarm LEDs, and a keypad for setting parameters and accessing logs. The panel indicates the system's operational state and potential faults through LEDs and acoustic alarms.

Human-machine interface (front panel) The front panel, which is identical for both AC and DC Systems, includes a comprehensive and flexible human-machine i nterface. It is divided into four sections: The system panel shows the system's current state of operation (which part of the system is currently supplying the load and which is in stand-by mode). LEDs also indicate possible faults. Oprations for turning on and off the system and a lamp test button for checking whether all LED indications are functioning properly. To shut down the system, you have to press the ON and OFF buttons at the same...
