BP-100V AS power supply uni
The BZh-100V power supply unit (further — the block) is intended for power supply by the stabilized tension of a direct current of the sensor of indication of level of the heat carrier (DIRT) in the control system of the steam-gas volume (SKUT) under a reactor cover for indirect measurement of level of the heat carrier in the reactor case.
The block belongs to the class of safety 3H on classification of NP 306.2.141-2008.
The block provides the output stabilized tension of a direct current in the range from 0 to 100 V.
The block provides the most permissible load up to 200 W.
The block provides the most admissible direct current of loading to 2 A.
The block provides management of output power of the unified current signal from 0 to 20 ma with a margin error no more than 1%.
The block provides control of output tension by which current and power of loading of value are displayed on the display.
The block provides diagnostic information transfer about loading power by means of the current unified signal from 0 to 20 ma (from 4 to 20 ma if necessary) which is galvanic separated from a power part of the block. To the unified signal from 0 to 20 ma there corresponds the power of load from 0 to 200 W. Transfer function linear.
The most admissible resistance of loading for the unified current signal of information transfer of loading power no more than 500 Ohms.
The block provides two operating modes: remote, operating power by means of the current unified signal from 0 to 20 ma and manual, operating power by means of buttons on the front panel of the block.
The block provides control of break of a transmission line of diagnostic information on power, at the same time on the display the inscription "ERROR OUT" appears.
Power supply of the block is carried out from two independent feeders of the alternating current main by voltage of 220 V (+22 —-33) In, with a frequency of 50 Hz ± 2 Hz.
The block provides light indication of emergency shutdown of automatic switches of food of one of feeders.
Power consumption of the block is no more than 300 V * And.
The mass of the block is no more than 25,0 kg.
Overall dimensions of the block no more than 450х125х330 mm.
Time of establishment of an operating mode of the block does not exceed 5 min. Operating mode of the block continuous.
Degree of protection of the block according to GOST 14254 — IP00.
In the block on the display the following information is displayed:
• value of the given power;
• value of output tension;
• value of current of loading;
• range of the unified current signal in which information about given out power is transferred.
Average operating time to the full blocks, not less than 125000 hours.
Middle service life of blocks not less than 15 years.
Middle period of storage of blocks no more than 3 years.
