Hasler tachographs in railway engines and traction units.
Input voltage range: 77 -137,5 VDC
Nominal output current: 1,20 A (+- 0.03 A)
Ambient temperature range: -30 C + 40 C
Weight: 1,1 kg
It converts input 77-137,5 V voltage into stabilized 1,2 A current independently from the changes of the resistance in the tachograph circuit.
Developed and made in Poland.
Note: Polish substitute is widely sold to state railways and maintenance shops in Poland.
