Stabilizer DC power supply J4V
Stabilizer has been made the use of the standard PC power supplies 300W. Has been added electronics for limiting the current (LED indicator overloads). Cooling are achieved using the original fan. Advantages performances are:
 small masses and dimension of devices (around 1,5kg with the box and additional elements)
 the large usability of strength of stabilizer
 simple and fast realization
Characteristics
 Power supply of complex: 220VAC / 1A
 Alternative performance of power supplies: 110VAC
 Protection from the overload of output
 The output voltage: 0..4,5V / 20A (or 0..12V / 10A)
 Is built in: digital LCD V / A,
 Dimensions: 250 * 200 * 100 (L * W * H)
 Possibly the parallel connecting more the stabilizer
Use
 electrolyses
 DC power supply
 filling of accumulator
 experimental purposes
Price: 850 HRK + parts
Example prices: 1650 HRK for the bottom example.
Example realizations
Options:
 possibly orders only remaking modules of power supplies and making control board for the adjusting of voltage and current without the implantation in in the box for 200 HRK + parts (on more than the 3 piece)
 without LCD of instrument
 without LCD of instrument, but with the connector for the connecting of the outer DVM (controls of voltages and current)
 the control board with the additional signalization for the achieving of the minimal current (npr 1A)
 the control board with the automatics for the switching off of output if the current limit continues more than e.g. the 30 second and repeated restart
 making documentations for the alteration of specific type of power supply also the design control board
 for the larger current (30A)
 with the output voltage from 0..12V practical (up15V!) and maksimal 10A the outputt current use 12V the output PC power supplies
 potentiometer for the regulation of the maximal current (instead of trimers on control board)
 other options on order (e.g. switching on the output in impulses, time limit with timer, etc)
Our experiences: reconstruction more than 30 PC power supplies for the need of stabilizer for the electrolysis appears good, low cost and fast solution of construction of such complexes.
