Milliamp Sources

Compact & mobile with battery supply - up to 20mA

The compact micro- and milliampere precision current sources generate currents proportional to an analog control voltage. The sources are supplied from batteries integrated in the housing of the source together with a recharger unit. Full functionality for controlling micro- and milliamps on ultra fast time scales and at ultra low noise level.
