Upon such an occurrence, V O will start to drop. Once the power supply has reached its maximum power limit, the protection will be activated. and the power supply will go into “Hiccup mode” (Auto-Recovery). The power supply will recover once the fault condition causing the OLP and OCP is removed and I O is back within the specified limit. Output Voltage (Vo) Load > 150% (Output Hiccup) 50% Load 50ms 50ms 50ms 50ms T (sec) 0% Load Inrush Current Inrush current is the input current that 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. 150% Load T (sec) Additionally, if the I O is <210% but >150% for a prolong period of time (depending on the load), the Over Temperature Protection (OTP) will be activated due to high temperature on critical components. The power supply will then go into hiccup mode until the fault is removed; and, the input voltage is removed, then reapplied. Over Temperature Protection 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 3 under “Protections”. Power supply will latch off, and require removal/re-application of input AC voltage in order to restart. 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 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 hiccup mode until the input voltage is removed; then, reapplied, and the surrounding air temperature drops to its normal operating temperature. Short Circuit Protection The power supply’s output OLP/OCP function also provides protection against short circuits. When a short circuit is applied, the output current will operate in “Hiccup mode”, as shown in the illustration in the OLP/OCP section on this page. The power supply will return to normal operation after the short circuit is removed. 9 All parameters are specified at 25°C ambient unless otherwise noted. www.DeltaPSU.com (November 2016, Rev. 02) TECHNICAL DATASHEET ``` MDS Medical AC-DC Open Frame 12Volt, 40Watt / MDS-040APS12 B Certificate .
