BLOCKS OF POWER SUPPLIES FOR CASES õëôó
(Technical conditions 31.1-30175784-006-2001 á)
Blocks of power supplies BPt-143 and BPt-144 are designed for:
replacement of P41240í/1-P and P41240í/2-P power supplies blocks that worked out their life time;
installation in cases UKTS-VL.
- BPt-143 is structurally compatible with P41240í/1-P
- BPt-144 is structurally compatible with P41240í/2-P
- BPt-143, BPt-144 surpass analogues in electric, reliability and weight parameters
- In BPt-143 there is no output voltage dependence of the "-15V" channel from settings of the output voltage and load current of the channel "+15V" (as distinct from P41240M/1-P)
- BPt-143, BPt-144 are installed into cases SB1 ÷ SB4 UKTS-VL.
- BPt-143 is installed into cases SRT1 ÷ SRT4 UKTS-VL
|
 |
|
BPt-145 and BPt-146 have same electric parameters, as well as blocks BPt-143 and BPt-144, but for all that have smaller weight and dimension
Blocks of power supplies BPt-145, BPt-146 are designed for installation in cases UKTS-VL:
- BPt-145 and BPt-146 are installed into SHB5÷SHB4 UKTS-VL;
- BPt-145 is installed into SRT5÷SRT8 UKTS-VL;
