General description:

The SDC 500 power supply system is intended for uninterruptible supply of 48Vdc loads by direct current in direct full-float operating mode. The construction of the system using cooperation of rectifiers type PDC 48/41-2000W or PDM 48/41-2000W and batteries under control of advanced Pi1 controller.

Application:

+ telecommunications and teletransmission;

+ IT applications;

+ industrial automation systems.

Design of the system:

In its standard version the power supply system is intended for stand-alone mounting or wall mounting. The system enclosure may be equipped with leveling feet.

The standard version the power supply system consists:

+ Distribution area AC/DC - height 19U;

+ Rectifier subrack 2U for installation up to. 12pcs. of rectifiers modules;

+ microprocessor control unit Pi1 with OLED color display, manipulator and RS232 or USB port for PC connection;

+ battery protections - fuse holder NH00 with fuses 160A - 2 pcs.;

+ loads protections: max. 14 x NH00 fuse holders or 26x MCBs;

+ signaling of load and battery protections blow-out;

+ LVD - automatic disconnection of the batteries from loads (protection against deep discharge);

+ measurement of output current and voltage;

+ summary battery current measurement;

+ independent current measurement of battery 1 and 2 (option);

+ separated battery charging by rectifiers allocated from the system (option).

Rectifiers:

Following rectifier modules may be installed in the system:

+ PDC 48/41-2000 with nominal output power 2000W;

+ PDM 48/41-2000 with nominal output power 2000W.

These modules are based on high-frequency technology of energy transformation with DSP (Digital Signal Processor) function. It means less number of components, optimized operation and active load sharing for increased reliability. The digital communication between rectifiers and control unit, gives operator the possibility of remote supervision on individual rectifiers of the system.
