CMS 356 CMS 356: 6 Phase Current + 4 Phase Voltage Amplifier The CMS 356 is a voltage and current amplifier for analog low-level signals provided by a CMC test set or by any other signal source, such as a digital real-time power system simulator. When used in combination with a CMC test set, the amplifier extends the capabilities of the test set to provide additional output channels and higher amplitudes. The high-amplitude and high-power current outputs make it equally suitable for testing modern numerical relays as well as high-burden electromechanical relays. The outputs of the voltage amplifier and the current amplifier are galvanically separated from each other and also from mains. Configuration and monitoring of the device status of the CMS 356 amplifier can be performed via the easy-to-use web interface. Key features: >> Six analog low-level inputs with selectable range (±7.071 Vpk or ±10 Vpk) >> Numerous output configurations, for example, 3 x 300 V + 3 x 64 A or 6 x 32 A >> Calculation and output of residual voltage and current >> Parallel connection of several CMS 356 units for even higher current amplitudes >> All current and voltage outputs are fully overload and short circuit proof >> Protection against voltage transient signal and over temperature Technical Data1 Current generators Setting range 6-phase AC (L-N) Voltage generators Setting range 4-phase AC (L-N) 1 x 0 ... ±180 A (Group A II B) 6 x 430 VA typ. at 25 A 6 x 250 W guar. at 20 A 3 x 860 VA typ. at 50 A 3 x 500 W guar. at 40 A 1 x 1000 VA typ. at 80 A 1 x 700 W guar. at 80 A 1 x 1740 VA typ. at 50 A 1 x 1100 W guar. at 40 A 1 x 1740 VA typ. at 25 A 1 x 1100 W guar. at 20 A 1 x 1400 W typ. at ±80 A 1 x 1000 W guar. at ±80 A Accuracy 3 Distortion (THD+N) 5 Max. compliance voltage (L-N)/(L-L)/(L-L-L-L) Connection banana sockets Connection combination socket Distortion (THD+N) 5 Ranges Connection All data specified are guaranteed, except where indicated otherwise.
