For our new measurement device programme, we are looking for a transformer, which has less than 0,07 dB voltage drop within a frequency range of 15 Hz up to 150 Hz. The primary impedance has to be lower than 0,5 Ohm.
Solution
A split tape-wound core (c-core) with very low iron losses and a good coupling.
Technical data
1AC-transformer 15 Hz bis 150 Hz Weight: 6 kg Frequency response: linear < 0,07 dB Power: 100 VA
