All parameters are specified at 25°C ambient unless otherwise noted. **www.DeltaPSU.com (November 2018, Rev.03)** 8 **TECHNICAL DATASHEET** **Medical ATX Power Supply** ATX 12V 1U Power Supply ## Dynamic Response The power supply output voltage will remain within ±10% of its steady state value, when subjected to a dynamic load 50 to 100% of its rated current. a 50 to 100% Load ## Over Temperature Protection As mentioned above, the power supply also has Over Temperature Protection (OTP). This is activated when the overload condition persists for an extended duration and the output current is below the overload trigger point but >100% load. In the event of a higher operating temperature condition at 100% load, the power supply will run into OTP when the surrounding air temperature is higher than the operating temperature. When activated, the output voltage will go into latch mode until the input voltage is removed; then, reapplied, and the surrounding air temperature drops to its normal operating temperature. ## Power Good ## Inrush Current Inrush current is the peak, instantaneous, input current measured and, occurs when the input voltage is first applied. For AC input voltages, the maximum peak value of inrush current will occur during the first half cycle of the applied AC voltage. This peak value decreases exponentially during subsequent cycles of AC voltage. The Power Good signal prevents a computer from attempting to operate on improper voltages and damaging itself by alerting it to improper power supply. The ATX specification defines the PowerGood signal as a +5 volt (V) signal generated in the power supply when it has passed its internal self-tests and the outputs have stabilized. This normally takes between 0.1 and 0.5 seconds after the power supply is switched on. The signal is then sent to the motherboard, where it is received by the processor timer chip that controls the reset line to the processor. When plug in AC power cord, +5Vsb will start first, then Remote On/Off will be pulled low by computer, +12V1/+12V2/+5V/+3.3V will power on and Power good signal will pull high after 100ms~500ms. After input AC is removed, Power Good signal changes to TTL Low at least 1 millisecond before any output falls out of regulation range. Graph illustrating the AC input, +5Vsb, Remote On/Off, +12V1/12V2/5/3.3V, Power good signal ## Overvoltage Protection The power supply’s overvoltage circuit will be activated when its internal feedback circuit fails. The output voltage shall not exceed its specifications defined on Page 4 under “Protections”. Power supply will latch off, and require removal/re-application of input AC voltage in order to restart. ## Short Circuit Protection The power supply’s output OLP/OCP function also provides protection against short circuits. When a short circuit is applied to any of the outputs, the power supply will latch off. ## Overload & Over current Protections The power supply’s Overload (OLP) and Over current (OCP) Protections will be activated before the output currents reach the limits defined on Page 4. Once the power supply has reached their maximum power limit, the protection will be activated and the power supply will latch off. ## Remote On_Off/INHIBIT Remote ON_OFF/INHIBIT can be used to enable or disable all outputs, except for the +5 Volt Standby. This signal can be pulled down to a low level of 0.3 volts, or shorted to DC-Return, in order for the main output to be enabled; and, floated (no connection to the signal), or pulled up to a value greater than or equal to 3 volts, in order to disable the main output. When the main output is disabled, the +5V Standby output will continue to operate. All parameters are specified at 25°C ambient unless otherwise noted. **www.DeltaPSU.com (November 2018, Rev.03)** 9 **TECHNICAL DATASHEET** **Medical ATX Power Supply** ATX 12V 1U Power Supply ## **Certificate** All Delta Medical Power products conform to the European directive 2011/65/EU.
