Hi, I'm one of the technicians working at the University of Bath. We have an Altair WBS-200 with a faulty Switch Mode PSU. Main unit is OK and will run on ext test PSU @24v. ZD1 has gone S/C and very charred. I'm guessing it is a 25.1v/5W Zener Dio

Hi, I'm one of the technicians working at the University of Bath.

We have an Altair WBS-200 with a faulty Switch Mode PSU. Main unit is OK and will run on ext test PSU @24v. ZD1 has gone S/C and very charred. I'm guessing it is a 25.1v/5W Zener Diode. Q1. Is this correct rating? Q2 .Is there a change/upgrade for this part?

Many thanks
