The power supply delivers its status signals as mentioned below. The signals are isolated from the power
supply by photocouplers.
• If the OVP trips when the power supply is set to power-OFF or crowbar-ON, the alarm
signal is turned ON for only approximately 60ms following the trip.
• The photocouplers are Toshiba TLP521-1 or equivalent.
