While some amplifiers offer direct measurements of small range current inputs. DEWESoft offers external 20mA, 5A, isolated 10A and isolated 20A shunts with accuracy down to 0.1% for direct AC or DC current measurements. Isolated voltage input amplifiers are required for connecting shunt resistor adapters.
All current sensors that require an additional power supply we offer integrated power supply option - SIRIUS PWR-MCTS2. With this option no external power supply needed. SIRIUS PWR-MCTS2 is a power supply unit for powering these current transducers directly from DEWESoft instruments without any external power supply. SIRIUS PWR-MCTS2 can be built into SIRIUS compatible chassis or directly into R1DB/R2DB, R4 or R8 data acquisition system.
