To fulfill the demands in maritime applications, the product is designed according to major industrial and maritime (Lloyd’s Register) safety standards. Other features include compliance with harmonic current IEC/EN 61000-3-2, class A. In addition to having Power Boost of 150% for 5 seconds, the CliQ M series is the first in the CliQ family to feature Advanced Power Boost (APB). With multiple loads connected in a system, a large outrush current could be drawn (demanded) due to one fault load. This will be detected by APB. The APB will trip the circuit breaker (circuit breaker with appropriate rating based on the system load) on the current path of the fault load due to high current. This thus prevents the system from shutting down while the other connected current paths continue to operate without interruption. Additionally, the product also includes built-in DC OK contact and LED indicator for DC OK/ Overload.

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’s output Short Circuit Protection function also provides protection against short circuits. When a short circuit is applied, the output current will operate in “Hiccup mode”.

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 7 seconds. If the power boost lasts longer than maximum duration, the output current will limit to 11A typ. and VO (output voltage) will start to droop and operate in “Constant Current mode”.

This APB will trip the circuit breaker (circuit breaker with appropriate rating base on the system load) on the current path of faulty load due to high current. This thus prevents the system from shutting down while the other connected current paths continue to operate without interruption. The following waveforms demonstrate the typical output voltage and output current when APB is activated. 24V 24V Output Voltage Output Voltage 50A 22V DC OK Relay Contact DC OK Relay Contact 10A 0A Output Current 2ms/DIV APB 200% of nominal output current for 50ms 24V Output Current 0A 20ms/DIV Fig. 7.1 18.4V Fig. 7.2 APB 500% of nominal output current for 2ms Output Voltage 50A 16.5V DC OK Relay Contact Output Current 0A 4ms/DIV Fig. 7.3 APB 500% of nominal output current for 5ms External Input Protection Device The unit is protected with internal fuse (not replaceable) at L pin and it has been tested and approved on 20A (UL) and 16A (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, please refer a minimum value in instruction sheet with B or C characteristic breaker. 16 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (July 2016, Rev. 01) TECHNICAL DATASHEET CliQ M DIN Rail Power Supply 24V 240W 1 Phase / DRM-24V240W1PN Operating Mode Redundant Operation PSU 1 PSU 2 DRR-20A In order to ensure proper redundant operation for the power supply units (PSUs), the output voltage difference between the two units must be kept at 0.45~0.50V for these 24V supplies. Follow simple steps given below to set them up for the redundant operation: LOAD Terminal 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 each power supply to 50% of rated load at any line voltage from 85-264Vac, and set the PSU 1 and PSU 2 output voltage. Com KEY DC OK Signal Terminal + Output - Common Signal L N PE Step 2. Connect the power supply units PSU 1 and PSU 2 to Vin 1 & Vin 2, respectively, of the DRR-20N (or 20A) module shown on the right of above diagram. Fig. 8 Redundancy Operation Connection Diagram Step 3. Connect the system load to Vout. Please note that output voltage Vout from DRR module will be = VO (output voltage of power supply) – Vdrop* (in DRR module). *Vdrop will vary from 0.60V to 0.90V (Typical 0.65V) depending on the load current and surrounding air temperature. Parallel Operation L 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 25mV of each other. This difference must be verified with the same output load connected independently to each unit. +V1 PSU 1 N N – –V1 + Load 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.

Power supply from the same product series only be used and with the same rated output current. 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 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 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 0.7V to 1.0V. It is recommended to provide sufficient de-rating for diodes use 2 times the voltage rating of series output voltage. E.g. the two 24V 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. PSU 2 ON PSU 1 ON Output Voltage (Vo) AC Input Voltage AC Input Current 18 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 startup waveform with 2 power supplies connected in series would see 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.

RoHS is the abbreviation for “Restriction of the use of certain hazardous substances in electrical and electronic equipment”. This product conforms to this standard. Conformal Coating The Protective Coating Technology Delta Electronics Group has designed the perfect dipping technique which penetrates everywhere including under device, and prevents leakage. 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. 20 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (July 2016, Rev. 01)
