For EMC engineers working with CS101 (MIL-STD-461G) or DO-160 testing, Schlöder offers a practical and complete solution: the MGA CT B-50/100 coupling transformer with an integrated differential amplifier. This clearly distinguishes this system from conventional coupling transformers, which often require external measurement setups to monitor the coupled voltage.
The built-in amplifier makes the measured differential voltage easily and accurately available, with switchable gain matched to both CS101 and DO-160 levels. This shortens the test setup and increases measurement reliability. Furthermore, the amplifier offers high common-mode rejection (>60 dB at 400 Hz), which is crucial for reproducible results in environments with a high number of interfering signals.
The MGA CT is available in two versions: 50 A and 100 A continuous load, both without saturation. The frequency response ranges from 10 Hz to 150 kHz (transformer) and up to 250 kHz (differential amplifier), enabling a wide range of audio frequency tests. An integrated, actively cooled 0.5 Ω precision resistor also simplifies CS101 power calibration.
For the user, this means fewer loose components, faster test setup, and consistent measurement results. All necessary connection cables are included as standard, and a current clamp up to ±100 A is optionally available for secondary current measurements.
