Product catalog summary

General Specifications:
The document outlines the features and specifications of the TescomR SD Series Rectifier. Key features include an internal isolation transformer, a fully controlled conventional rectifier, and smart control with a Digital Signal Processor (DSP). It supports various charging modes (float, equalizing, boost) and offers both automatic and manual charge modes. The rectifier is equipped with a 2x16 character LCD display, LED indicators, and an audible alarm for status monitoring. It allows for programmable current limitation and can operate as either a voltage or current source. Language selection is available from the front panel, supporting multiple languages.

Technical Specifications:

Input: Nominal voltage options include 190VAC to 415VAC with a tolerance of ±15%. The nominal frequency is 50Hz/60Hz, and the input is protected by thermic magnetic overcurrent protection.
Output: Output voltage options range from 12VDC to 220VDC, with adjustable output and battery charging currents. The rectifier supports a maximum output current of 100% of the nominal output current.
General Properties: Features include a boost timer, fan-forced cooling, and various protection levels (IP20 standard, optional up to IP54). Efficiency ranges from 85% to 93% at full load.
Environment: The rectifier operates within a temperature range of -5ºC to +50ºC and can be stored between -20ºC and +70ºC. It supports altitudes up to 4000m with power derating above 1000m.
Communication & Paralleling: Standard communication includes RS232 and dry contacts, with optional RS485, Modbus TCP, SNMP, and GSM. The system supports parallel redundant operation without additional kits.

Standards:
The rectifier complies with standards IEC60146, IEC62040 1-2, ISO9001, and ISO14001.
