IN15 Power Supplies

The power supplies for the correction coils of the long Fourier time spin-echo spectrometer IN15 are approaching the end of their life time and will be replaced by new power supplies. These correction coils are needed to make fine adjustments to the main precession field generated by the main precession coils. The power supplies for the correction coils are current controlled, low tension power supplies. The call for tender is separated in 2 packages. The power supplies in package 1 should be able to supply up to 20 A and should be bipolar. The power supplies in package 2 should be able to supply up to 60 A
