Rise Time The time required for the output voltage to change from 10% to 90% of its final steady state set value. Hold-up Time Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value. Inrush Current Dynamic Response 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. The power supply output voltage will remains within ±5% of its steady state value, when subjected to a dynamic load from 0% to 100% of its rated current. 11  50% duty cycle / 5 Hz to 1 KHz All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (June 2021, Rev. 07) TECHNICAL DATASHEET CliQ II DIN Rail Power Supply 24 V 240 W 3 Phase / DRP024V240W3B□ Power Boost Power Boost is the reserve power available constantly that allows reliable startup to support sudden and short spike of loads with high inrush current typically during turn on to remove the need of more expensive higher rated power supply unit. After the output has reached its steady state set value, the power supply can support surge loads with a higher short-term power demand up to 150% of maximum rated load (IO Max), for a maximum duration of 5 seconds.

External Input Protection Device The unit is protected with internal fuse (not replaceable) at L1, L2 and L3 pins, which have been tested and approved on 20 A (UL) and 16 A (IEC) branch circuits without additional protection device. An external protection device is only required if the supplying branch has an ampacity greater than above. Thus, if an external protective device is necessary, or, utilized, a minimum value of 13 A B- or 6 A Ccharacteristic breaker should be used. 12 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (June 2021, Rev. 07) TECHNICAL DATASHEET CliQ II DIN Rail Power Supply 24 V 240 W 3 Phase / DRP024V240W3B□ Overload & Overcurrent Protections (Auto-Recovery) Overvoltage Protection (Auto-Recovery) The power supply’s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current (IO) exceeds its specification as defined on Page 4 under “Protections”. In such occurrence, the output voltage (VO) will start to droop and once the power supply has reached its maximum power limit, the protection is activated and the power supply will go into “Hiccup mode” (AutoRecovery). The power supply will recover once the fault condition of the OLP and OCP is removed and IO is back within the specifications. 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”. Over Temperature Protection (Auto-Recovery) It is not recommended to prolong the duration of IO when it is less than OLP/OCP point, but greater than 100%, since it may cause damage to the PSU. As described in load de-rating section, the power supply also has Over Temperature Protection (OTP). In the event of a higher operating temperature at 100% load, the power supply will run into OTP when the operating temperature is beyond what is recommended in the de-rating graph. When activated, the output voltage will go into bouncing mode until the temperature drops to its normal operating temperature as recommended in the de-rating graph. Short Circuit Protection (Auto-Recovery) 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. 13 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (June 2021, Rev. 07) TECHNICAL DATASHEET CliQ II DIN Rail Power Supply 24 V 240 W 3 Phase / DRP024V240W3B□ Operating Mode  Redundant Operation In order to ensure proper redundant operation for the power supply unit (PSU), the output voltage difference between the two units must be kept at 0.45~0.50 V for 24 V supplies. Follow simple steps given below to set them up for the redundant operation: Step 1. Measure output voltage of PSU 1 and PSU 2. If PSU 1 is the master unit, then VO of PSU 1 must be higher than PSU 2. In order to set the output voltage, individually connect the power supply to 50% of rated load at any line voltage, and set the PSU 1 and PSU 2 output voltage. Step 2. Connect the power supply units PSU 1 and PSU 2 to Vin 1 & Vin 2, respectively, of the DRR-20N (or 20 A) module shown on the diagram on the right. Step 3. Connect the system load from Vout. Please note that output voltage Vout from DRR module will be = VO (output voltage of power supply) – Vdrop* (in DRR module). **The Signal GND in the DRR module is for the built-in LED and DC OK signals. The Output GND terminals from the two PSU’s do not need to be connected to the Signal GND terminal. Fig. 4 Redundant Operation Connection Diagram Fig. 5 Parallel Operation Connection Diagram *Vdrop will vary from 0.60 V to 0.90 V (Typical 0.65 V) depending on the load current and surrounding air temperature  Parallel Operation The power supply units (PSUs) can also be used for parallel operation in order to increase the output power. The difference in output voltage between the two units must be kept to within 25 mV of each other. This difference must be verified with the same output load connected independently to each unit. Parameters such as EMI, inrush current, leakage current, PARD, start up time will be different from those on the datasheet, when two units are connected in parallel. The user will need to verify that any differences will still allow the two power supplies connected in parallel will work properly in their product/application. 14 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (June 2021, Rev. 07) TECHNICAL DATASHEET CliQ II DIN Rail Power Supply 24 V 240 W 3 Phase / DRP024V240W3B□ Fig. 6  Series Operation Connection Diagram Series Operation Delta's CliQ II can be connected in series to increase the output voltage as shown in figure above. Only power supply from the same product series, and with the same rated output current, can be used. The maximum load current should not exceed the smallest rated output current. Any number of power supplies can be connected in series. User must note that an output voltage > 60Vdc will not meet SELV requirements and could be dangerous to user, the total voltage shall not exceed 150Vdc. Installation a protection against the touching is a must and connect the output ground to earth when output voltage is not SELV. A diode in reverse bias must be added across output terminals of each power supply, this is to prevent -V voltage being applied to other power supply in fault conditions such as short circuit across load. During the short circuit -V1 & +V1 will come across +V2 & -V2 which means connecting 2 power supplies in opposite polarity and may cause damage to power supply. With reverse bias diodes in place the voltage across each power supply will be restricted to one diode drop – approximately 0.7 V to 1.0 V. It is recommended to provide sufficient voltage de-rating for diodes with 2 times the voltage rating of series output voltage. E.g. the two 24 V power supplies are connected in series, the total voltage is 48 volts. Hence, recommended to use diodes with reverse voltage rating of 2x48 = 96 volts. Therefore diodes with reverse voltage rating of 100 volts can be used. During the short circuit condition, the current through diodes will be large, hence it is recommended that diodes to be least twice the current rating of the power supply. The turn ON would be non-monotonic as the power supply with the fastest startup time and rise time will turn on first. As a result, the combined output voltage waveform of the 2 power supplies connected in series will include a step. User must consider to verify parameters such as EMI, inrush current, leakage current, PARD, start up time would differ from datasheet numbers as multiple power supplies in series. 15 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (June 2021, Rev. 07) TECHNICAL DATASHEET CliQ II DIN Rail Power Supply 24 V 240 W 3 Phase / DRP024V240W3B□ Fig. 7  DC Input Operation Connection Diagram DC Input Operation Step 1.

The conformal coating dipping can be applied to PCBAs or circuit board. The coating preserves the performance of precision electronic primarily by preventing ionizable contaminants such as salt from reaching circuit nodes, where the material slumps around sharp edges. This can be a problem especially in highly conversing atmosphere. PFC – Norm EN 61000-3-2 Line Current Harmonic content Typically, the input current waveform is not sinusoidal due to the periodical peak charging of the input capacitor. In industrial environment, complying with EN 61000-3-2 is only necessary under special conditions. Complying to this standard can have some technical drawbacks, such as lower efficiency as well as some commercial aspects such as higher purchasing costs. Frequently, the user does not profit from fulfilling this standard, therefore, it is important to know whether it is mandatory to meet this standard for a specific application.
