10 / 27 page UC10.241, UC10.242 UC-Series 24V, 15A, CAPACITOR-BASED DC-UPS 9. PC-MODE The PC-mode always turns the output off for at least 5s after a buffer event lasting longer than 1s, independent of whether the 24V may have recovered during this time. This function ensures that the PC gets a restart signal. To enable a safe shut-down of the system, the forced turn off of the output is delayed with a constant time of 70s. To activate the PC-mode, connect the two pins marked with “PC-mode” together on the signal connector together. If the reset is to be controlled by the PC and not the DC-UPS, a wiring option called “external controlled delayed shut- down” is available. See section 23.8 for details. Fig. 9-1 PC-Mode - Buffer event ends before buffer capacitors are discharged and buffer event is shorter than 70s >1s Power Supply Output DC-UPS Output full empty Capacitor Ready Contact closed open Buffering Contact closed open 5s 70s Example A: The buffer event is longer than 1s and ends before the buffer capacitors are fully discharged. After 70s of the beginning of the buffer event, the output of the DC- UPS will be switched off for 5s. Fig. 9-2 PC-Mode - Buffer event discharges the buffer capacitors before the input recovers Power Supply Output DC-UPS Output full empty Capacitor Ready Contact closed open 10/27 Buffering Contact closed open 5s Example B: The buffer event lasts longer than the buffer capacitors can supply the output. The buffer capacitors are fully discharged before the input voltage recovers. The DC-UPS output will turn-on earliest 5s after the power supply output voltage has recovered. May 2016 / Rev. 2.2 DS-UC10.241-EN All parameters are specified at 24V, 10A output current, 25°C ambient and after a 5 minutes run-in time unless otherwise noted. www.pulspower.com Phone +49 89 9278 0 Germany |
