ONTACT
This feature monitors the output voltage, which is produced by the power supply itself. It is independent of a back-fed
voltage from a unit connected in parallel to the power supply output.
Contact closes As soon as the output voltage reaches 90% of the adjusted output voltage level.
Contact opens As soon as the output voltage dips more than 10% below the adjusted output voltage.
Short dips will be extended to a signal length of 100ms. Dips shorter than 1ms will be ignored.
Contact ratings max. 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A resistive load
min. 1mA at 5Vdc min. permissible load
Isolation voltage See dielectric strength table in section 18.
