Omicron CMS 356 Voltage and current amplifier

Code: Omicron CMS 356

Datasheet

PDF, 0.35 Mb

Description

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 network 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 the inputs as well as from the mains. Configuration and monitoring of the device status of the CMS 356 amplifier can be performed via the easy-to-use web interface.

Features:

Six analog low-level inputs with selectable range (½7.07 Vpk or ½10 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
