I just got this power supply today
Can someone tell me what the S+, S- and RTN pins are for? I assume the RTN is the common ground for the outputs but have no idea that S+ and S- are for. I know it's not for input since there is an ACL, ACN and GND connection on the other side.
Those connections are call sensing connections. The voltage at a remote location can be monitored and the supply will keep regulation using the voltage at that location. If you are not using that feature the S+ will be jumped to the V+ and the S- will be jumped to the S-.
Did the supply come with a manual?
Regards, Tom
