In March, 2015 the design office of Transconverter started the development of testing stand SI10 UHL4.

Stand SI10 UHL4 under development is designed to test supply of AC locomotives.

Stand SI10 UHL4 will have adjustable from 280 to 470 V single phase output with frequency 50 Hz and four built-in discretely adjustable loads with a capacity of 7 kW, 2.3 kW, 1.5 kVA and 1.2 kVA.

Stand SI10 UHL4 will have a power cabinet and a remote operator desk using which it will be possible to set output single-phase voltage value and connect different loads to the cabinet.
