INSTRUCTIONS APSDC1202A 3.2 Technical outputs The PSU has indication outputs: • EPS - absence of AC supply output: - OC type output that indicates AC power loss. Under normal status, with 230V AC supply, the output is connected to ground (L level – 0V). In case of power loss, the PSU will switch the output into high impedance state hi-Z.
