Yes, that is the units that I have.
Thank you for a swift response and sorry for my delay. Just to make sure. I have 2 completely isolated 48 volt dc power supplies. They are isolated with 2 ‘isolation transformers’ one on each 48 volt supply. Under these conditions is it not possible to connect the two DP50v5A units in series to get a split supply +15, 0, -15 vdc with common zero.
Thank you for your patience and help.
