Rise Time The time required for the output voltage to change from 10% to 90% of its set value. Hold-up Time Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time required for the output to reach 95% of its set value, after the input voltage is removed. ■ Graph illustrating the Start-up Time, Rise Time, and Hold-up Time 8 All parameters are specified at 25°C ambient unless otherwise noted. www.DeltaPSU.com (July 2013, Rev. 00) TECHNICAL DATASHEET MDS Medical AC-DC Open Frame 24V 40W / MDS-040APS24 BA Dynamic Response Overload & Over current Protections The power supply output voltage will remain within ±3% of its steady state value, when subjected to a dynamic load 50 to 100% of its rated current. ■ 50 to 100% Load 100% Load The power supply’s Overload (OLP) and Over current (OCP) Protections will be activated when output current between150% and 210% of IO (Max load). In such occurrence, the VO will start to drop and once the power supply has reached its maximum power limit, the protection is activated and the power supply will go into “Hiccup mode” (Auto-Recovery). The power supply will recover once the fault condition of the OLP and OCP is removed and IO is back within the specifications. Output Voltage (Vo) Load < 210% (Output Hiccup) 50% Load 50ms 50ms 50ms 50ms T (sec) 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. 0% Load 150% Load T (sec) Additionally, if the IO is <150% but >100% 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 latch mode until the fault is removed and the mains is reapplied. 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 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 main is reapplied and the surrounding air temperature drops to its normal operating temperature. 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. 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 (July 2013, Rev. 00) TECHNICAL DATASHEET MDS Medical AC-DC Open Frame 24V 40W / MDS-040APS24 BA Certificate .
