Hello. I currently have with me a TRACO Power TES 2-1222H DC/DC converter. The model I have has an input of 12V and is meant to output 12V (plusminus 10%) as also shown by the datasheet: With a steady input of 12.6V into the -Vin (Gnd) and +Vin (Vcc) I am able to measure 36V across the +Vout and -Vout pins and 20V across the +Vout and common pin. I have used two loads and an open circuit with the same results. Anyone have any ideas of why this is happening?
