Resolution

In the current MNB controller line, the MNB-1000 is full-wave rectified. The MNB-300, MNB-70, and MNB-Vx are half-wave rectified.

In the current MNL controller line, the MNL-800 is full-wave rectified. The MNL-5Rxx, MNL-1xRxx, MNL-20Rxx, and MNL-VxRxx are half-wave rectified.

An early version of the MNL controllers were full-wave rectified: MNL-Pxx, MNL-Uxx, and MNL-Vxx (firmware V1.x). The same controllers were upgraded to firmware V2.x and re-designed for half-wave rectification. Both firmware versions of this controller line are obsolete.
