Omicron's CMC 256 relay test sets generate the test signals digitally, resulting in highly accurate testing signals even at small amplitudes. The electronic design of the internal amplifiers and the use of switch mode power supply units ensure a minimum of weight and volume is achieved. Independent channels with low-level signals are available at the back of the test set, which can be used to control external amplifiers for applications requiring more signal channels or higher currents, voltages or power. The low-level signals can also be used for test objects which have a low-level input facility.

All generators are continuously and independently adjustable in amplitude, phase and frequency and no switching of ranges is necessary. All current and voltage outputs are fully overloaded, short-circuit proof and are protected against external high-voltage transient signals and over-temperature. Every device is developed according to international IEC standards and verified by independent certification bodies including UL and TÜV. For testing that requires higher outputs a CMA 156 - 6 Phase Current Amplifier can be used along with the CMC 256.
