medical ac - dc enclosed power supply 12v 400w 3 .5 ? x5 .5 ? high density mds - 400a db12 aa 9 functions start - up time the time required for the output voltage to reach 90% of its set value, after the input voltage is applied. rise time the time required for the output voltage to change from 10% to 90% of its set va lue. 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 req uired for the output to reach 9 0 % of its set value, after the input voltage is removed. graph illustrating the start - up time, rise time, and hold- up time dynamic response the power supply output voltage will remain within 5 % of its steady state value, when subjected to a dynamic load 50 to 100% of its rated current. 50 to 100% load 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. 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. all parameters are specified at 25 c ambient unless otherwise noted. www. deltapsu .com ( november 201 6 , rev. 0 3 )
medical ac - dc enclosed power supply 12v 400w 3 .5 ? x5 .5 ? high density mds - 400a db12 aa 10 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 . overload & overcurrent protections the power supply?s overload (olp) and overcurrent (ocp) protections will be activated before output current under 1 6 0 % of i o (max load). upon such occurrence, v o will start to dro p. o nce the power supply has reached its maximu m power limit, the protection will be activated and the power supply will go into ?hiccup mode? (auto - recovery). the power supply will rec over once the fault condition causing the olp and ocp is removed and i o is back within th e specified limit. additionally, if the i out is <1 6 0% but >1 0 0% 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. then, t he power supply will be latch ed off, and require recycling of input voltage to restart it. 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 hi gher 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 remov ed; then, reapplied , and the surrounding air temperature drops to its normal operating temperature. power good power good+ pin is an open collector transistor (40v/600ma rating). a resistor (suggested value 10kohm, 1/8w) can be added between 5 v standby pin (or, other available pull - up voltage that is no greater than 30v ) and the power good+ pin (refer to figure below). value of pull - up resistor may have to be adjusted, depending on voltage used, and other end - use conditions of the power good+ pin connection to the product. when ac input is on, power good+ pin will be high. when ac input is off, power good+ pin will be l ow. there will be a minimum of 3 milliseconds between the time the power good goes to low level, and the time when the output reaches 90% of its rated value. remote on_off/inhibit remote on_off/inhibit can be used to enable or disable only the main output. when the main output is disabled, the +5v standby output will continue to operate. 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. remote sense remote sense feature can be used to compensate for the extra voltage drop on output wires that are connected from the main output terminals, to the load. with wires connected from the remote sense pins, at the same locations as the wires from the main output, the remote sense function can compensate up to 500mv voltage drop. the power supply will not be damaged if the remote sense pins are shorted, o r if a reverse/inverted polarity connection is made to the load. all parameters are specified at 25 c ambient unless otherwise noted. www. deltapsu .com ( november 201 6 , rev. 0 3 )
