Mechanical Specification 85 124 142 TB1 Terminal Pin. No Assignment Pin No. 1 2 3 4 5 Assignment (1 phase) N / AC L / AC Jumper 115V AC Jumper 115V AC FG TB2 Terminal Pin. No Assignment Pin No. 1,2 3,4 5,6 Assignment DC output -V DC output +V DC OK relay contacts DC OK Relay Contact Outputs are used for preventive function monitoring of the power supply. An electrically isolated signal contact is available. The signal contact closes when the output power is OK and opens when the output voltage falls below 20Vdc ±5%. Output Derating Curve Parallel Connection A parallel connection with the same model power supply can be set up to increase the output power. The output has to be adjusted approximately to the same value (± 20mV) while applying a 1-2 A load to all devices before connecting them in parallel. In PSA-600xx, for more power, the position of the Easy Parallel jumper needs to be changed to enable a parallel connection. In this mode up to 4 power supplies can be put together in parallel. + AC DC – + AC DC – + – LOAD Note: All dimensions are in millimeters, to convert to inches multiply by 0.03937.
