Siłownia.

General description:

The SDC 250-02 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 system is intended for stand-alone mounting or wall mounting. It may be equipped with leveling feet.

+ Distribution area AC/DC - height 21U;

+ Rectifier subrack 2U for installation up to. 6pcs. 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) (option);

+ 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).

Features:

+ high flexibility for system extension;

+ modern, constant power rectifiers;

+ easy installation of rectifier (replacement or extension) during normal operation status (hot-swap);

+ continuous control of system's operation and fast reporting of alarm states by means of controller;

+ very high efficiency (PDM 48/41-2000W);

+ immunity to short-circuits and overloads of output circuits;

+ immunity to electromagnetic interferences.

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.
