switch mode power supply drp024v 0 60w 1ba 8 / 13 rev: 00 , 1/10/2011 ? overl oad protection the power supply is provided with an overload protection (olp) function which protects the power supply from possible damage caused by excess current. the power supply also has an over temperature protection (otp) in case overload condition persists for a n extended duration and is below the overload trigger point but > 100% load. typically the overload current ( i ol ) is > i surge (150%) output voltage will start dropping when the power supply reaches max power limit. it will go into bouncing mode when the output reaches uvlo (under voltage point). the output voltage will recover automatically when the overload condition is removed . ? short circuit protection the power supply has a short circuit protection which is in line with the overload protection and activates whenever there is a short across the output voltage. it will go into bouncing mode and recovers automatically wh en the fault is removed. ? over temperature protection the power supply has an 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 ambient operating condition at 100% load, the power supply will run into otp when the ambient temperature is > 55 c. when activated, the output voltage will go into bouncing mode until the operating ambient temper ature drops to 50 c or output capacity is reduced as recommended in the graph.
switch mode power supply drp024v 0 60w 1ba 9 / 13 rev: 00 , 1/10/2011 ? overv oltage protection the power supply has an overvoltage protection (ovp) and is activated when the power supply feedback circuit fails. the output voltage will not be > 35v under any line/load and operating ambient temperature. the power supply does not shut down but goes into hiccup mode (auto - recovery). the output voltage will recover back to 24vdc once the fault is removed. ? inrush curren t, start - u p time, output ho ld - u p time inrush current, inrush current is the first surge current seen on the input side when ac input is applied to the power supply. it is the first pulse captured. see below for the inrush current in a typical power supply. start - u p time, start - up time is measured from the point ac input is applied to the point output voltage reaches within 90% of its set value. see below for a typical start - up time characteristic. rise time, rise time is measured from the point output voltage rises from 10% to 90% of its set value. see below for a typical rise time measurement.
switch mode power supply drp024v 0 60w 1ba 10 / 13 rev: 00 , 1/10/2011 ho ld - u p time, hold time is the time when the ac input collapses and o/p voltage retains regulation for a certain period of time is called as hold up time. see in the picture below a typical hold up time characteristic of a power supply. the hold time is measured until t he output voltage remains in regulation hence it measured until the output voltage reaches min imum regulation - 2% of its set value. ? output voltage adjust the 24vdc connection is made using the "+" and " C " screw connections. at the time of deliv ery, the output voltage is 24v dc. the output voltage can be set from 2 4 to 28vdc on the potentiometer seen as adjust on the front panel of each power supply.
switch mode power supply drp024v 0 60w 1ba 11 / 13 rev: 00 , 1/10/2011 ? surge load see below typical surge load capability of the power supply, the psu is capable of delivering 3 secs of surge load about 150% of i o max the o/p voltage can be out of regulation limits of + 5%. ? dynamic load the p ower s upply is capable of dynamic output voltage load change from 10 % to 9 0% within 5% of regulation limits, a nd from 0% to 100% within 10% of regulation limits . see picture below on the dynamic behavior of the p ower supply .
switch mode power supply drp024v 0 60w 1ba 12 / 13 rev: 00 , 1/10/2011 ? redunda ncy & parallel operation with or ing diode see picture below for a typical redundant/parallel operation using cliq ii series power supplies. power supply unit 1 (psu1) and power supply unit 2 (psu2) are connected through a twin diode where anode 1 ( a1) is connected to the +ve of psu1 and a2 is connected to the +ve of psu2 and both output ground are shorted together. the output of psu1 and psu2 is drawn from the cathode k of the twin diode, making the power supply work in redundant/parallel operation . redundant operation: when 2 power supplies are connected in parallel, the power supply with the higher output voltage will take the maximum load while the other will operate in standby mode (at no load). in case the first power supply fails, the second will take over the load and supplies the required power to the end system.
switch mode power supply drp024v 0 60w 1ba 13 / 13 rev: 00 , 1/10/2011 parallel operation: when 2 power supplies are connected in parallel, they can share the load if the following steps are taken. step 1: measure the output voltages at no load from a1 to ground i.e. va1 to ground of psu1 and va2 to ground of psu2. if the voltages are not the same, follow step 2. if they are the same, skip to step 3. step 2: adjust the output voltages, with the help of vr on the power supply front panel market as adjust, to the same level. for e.g. if psu1 is measuring 24. 15vdc and psu2 is measuring 24 .25vdc, adjust the output voltage of one to be the same as the other. step 3: connect the power supply to the end system load and measure the output volt ages from a1 to ground i.e. va1 to ground of psu1 and va2 to ground of psu2. ensure that the output voltages are the same even after the 2 power supplies are connected to load. if not, adjust them with the vr available on the front panel. a tolerance of +/ - 25mv would be acceptable. note: 1 . if the output voltage of any power supply is higher, it will take the initial load and share the maximum load. 2 . if the output voltages are the same, then an equal load current sharing between the 2 power supplies can be achieved. 3 . the oring diode must be of an appropriate rating. the rating must be at least 4 times of the output load current and at least reverse voltage rating of 20vrr. 4 . the use of a heat sink is advised to ensure the oring diode does not overheat. 5 . recommended redundancy module : drr - 20a
