7 / 9 page HPS3000 Series Data Sheet Signals and Controls - All Models PSON# The PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low signal that turns on the 48 V power rail. When this signal is not pulled low by the system, or left open, the 48 V output turns off. The 5 Vsb output remains on. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply. The power supply fan(s) shall operate at the lowest speed. PSON# Signal Characteristic Signal Type Accepts an open collector/drain input from the system. Pulled-up to the 5 Vsb located in power supply. PSON# = Low ON PSON# = Open OFF MIN MAX Logic level low (power supply ON) 0 V 0.4 V Logic level high (power supply OFF) 2.40 V 3.40 V Source current, Vpson = low -- 4 mA Power up delay: Tpson_on_delay 5 msec 400 msec Timing Signal Definitions Turn ON/OFF Timing Item Description Min Max Units Tvout_rise 48 V Output rise time 5 300 msec Tsb_on_delay Delay from AC being applied to 5 Vsb being within regulation. 1500 msec Tac_on_delay Delay from AC being applied to all output voltages being within regulation. 2000 msec Tvout_holdup Time all output voltages, including 5 Vsb, stay within regulation after loss of AC. 10 msec Tpwok_holdup Delay from loss of AC to de-assertion of PWOK 5 msec Tpson_on_delay Delay from PSON# active to output voltages within regulation limits. 5 400 msec Tpson_pwok Delay from PSON# de-active to PWOK being de-asserted. 50 msec Tacok_delay Delay from loss of AC input to de-assertion of ACOK#. 10 msec Tpwok_on Delay from output voltages within regulation limits to PWOK asserted at turn on. 100 1000 msec Tpwok_off Delay from PWOK de-asserted to 48 V dropping out of regulation limits. 1 1000 msec Tpwok_low Duration of PWOK being in the de-asserted state during an off/on cycle using AC or the PSON# signal. 100 msec Tsb_vout Delay from 5 Vsb being in regulation to 48 V being in regulation at AC turn on. 50 2000 msec |
