We input about 120 Vac, connect B+ and B- to get about 22.5 Vdc, which does not meet the safe operating area, what may be the reason?

Asked by: Silvia
Please refer to user's manual M0563-0504. You can download it off our website. It states that jumpers need to be installed between Terminal 1&2 and between Terminal 3&4. Without these jumpers the power supply will generate a 22 volt output and the adjustment potentiometer will not function.
