Measuring Amplifier System MGCplus

Special features

The MGCplus system is tested according to the harmonized European standards EN61326 and EN61010 Therefore it achieves the protection aims of EEC directive 89/336EEC in the field of electromagnetic compatibility and EEC directive 73/23/EEC in the field of electrical safety of low voltage equipment. Mechanical stress is tested according to European Standard EN60068-2-6 for vibrations and EN60068-2-27 for shock. The equipment is exposed to an acceleration of 25 m/s2 within the frequency range of 5...65 Hz in all 3 axes. Duration of this vibration test: 30 min per axis. The shock test is performed with a rated value of 200 m/s2 acceleration during 11 ms, half sine pulse shape, with 3 shocks in each of the 6 possible directions.

The maximum capacity of drawn current on each MGCplus slot is 150 mA in a 16 slots housing. The double capacity on every used slot is possible, if the next slot of each used one is left free.
