medical ac - dc enclosed power supply 12 v 30 0w with 5v/0.5a standby / mds - 300 a db 12 a a technical datasheet all parameters are specified at 25 c ambient unless otherwise noted. www. deltapsu .com ( november 201 6 , rev. 0 4 ) 10 dynamic response ( 12 volt output) 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. inrush current inrush cu rrent 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 t he applied ac voltage. this peak value decreases exponentially during subsequent cycles of ac voltage. overvoltage protection the power supplys overvoltage circuit will be activated when its internal feedback circuit fails. the output voltage shall not exceed its specifications defined on page 5 under protections. power supply will latch off, and require removal/re - application of input ac voltage in order to restart. overload & over current protections the power supplys overload (olp) a nd over current (ocp) protections will be activated before the 12 volt output s current exceeds 1 6 0 % of i o (max load). upon such an occurrence, v o will start to drop. once the power supply has reached its maximum power limit, the protection will be activat ed 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. for the standby output, the performance is the same, wi th the exception that the protection will be activated before the output current exceeds 1.06 amps. additionally, if the 12 volts i out is >1 0 0%; but <1 6 0% for a prolong ed period of time (depending on the load), the over temperature protection (otp) wil l be activated due to high temperature on critical components. the power supply will then go into latch mode . short circuit protection the power supplys output olp/ocp function also provides protection against short circuits. when a short circuit is app lied, 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 . 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 tempe rature 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.
medical ac - dc enclosed power supply 12 v 30 0w with 5v/0.5a standby / mds - 300 a db 12 a a technical datasheet all parameters are specified at 25 c ambient unless otherwise noted. www. deltapsu .com ( november 201 6 , rev. 0 4 ) 11 power good power good+ pin is an open collector transistor (40v/600ma rating). a resistor (suggested value 10kohm, 1/8w) can be added between 5v standby pin (or, oth er 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 p roduct. when ac input is on, power good+ pin will be high. when ac input is off, power good+ pin will be low. there will be a minimum of 5 milliseconds (at 19 0w load) 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 l ow 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 remo te sense function can compensate up to 500mv voltage drop. the power supply will not be damaged if the remote sense pins are shorted, or if a reverse/inverted polarity connection is made to the load.
