General description:

The SDD 400 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 PDD 48/67-3200W or PDJ 48/73-3500W and batteries under control of advanced Pi1 controller.

Application:

+ professional telecommunications systems;

+ IT network systems;

+ GSM / UMTS backbone stations;

+ 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 standard version the power supply system consists:

+ Pi1 controller with LCD display and manipulator;

+ rectifier subrack (3U) intended for installing up to 6 pcs. of rectifier modules;

+ battery protections - NH00 fuses - 2 pcs.;

+ load protections:

- fuse holder NH1-3 - 1 pc.

or

- fuse holder NH00 - up to 16 pcs.

or

- magnetic circuit-breakers (MCB) - up to 30 pcs.;

+ signalling of load and battery protections blow-out;

+ output current and output voltage measurement;

+ summary battery current measurement;

+ individual measurement of Battery 1 and 2 current (option);

+ separated battery charging by rectifiers allocated from the system;

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

+ temperature compensation of float voltage with temperature sensor.

Rectifiers:

Following rectifier modules may be installed in the system:

+ PDD 48/67-3200W with nominal output power 3200W;

+ PDJ 48/73-3500W with nominal output power 3500W.

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.
