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. ## Dynamic Response The power supply output voltage will remains within ยฑ2% of its steady state value, when subjected to a dynamic load from 0% to 100% of its rated current. All parameters are specified at 25ยฐC ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (December 2018, Rev. 04)** 11 **TECHNICAL DATASHEET** ## **CliQ II DIN Rail Power Supply** 48V 60W 1 Phase / DRP048V060W1B โ–ก ## 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.

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. All parameters are specified at 25ยฐC ambient and AC input unless otherwise indicated. 12 | **www.DeltaPSU.com (December 2018, Rev. 04)** **TECHNICAL DATASHEET** ## **CliQ II DIN Rail Power Supply** 48V 60W 1 Phase / DRP048V060W1B โ–ก ## Overload & Overcurrent Protections (Auto-Recovery) The power supplyโ€™s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current exceeds 150% of IO (Max load). In such occurrence, the 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 โ€œHiccup modeโ€ (Auto-Recovery). The power supply will recover once the fault condition of the OLP and OCP is removed and IO is back within the specifications. supply will return to normal operation after the short circuit is removed. ## Overvoltage Protection (Auto-Recovery) The power supplyโ€™s overvoltage circuit will be activated when its internal feedback circuit fails. The output voltage shall not exceed its specifications defined on Page 3 under โ€œProtectionsโ€. ## Over Temperature Protection (Auto-Recovery) It is not recommended to prolong the duration of IO when it is <150% but >100%, since it may cause damage to the PSU. ## Short Circuit Protection (Auto-Recovery) The power supplyโ€™s output OLP/OCP function also provides protection against short circuits. When a short circuit is applied, the output current will operate in โ€œHiccup modeโ€, as shown in the illustration in the OLP/OCP section on this page. The power 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 derating graph. All parameters are specified at 25ยฐC ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (December 2018, Rev. 04)** 13 **TECHNICAL DATASHEET** ## **CliQ II DIN Rail Power Supply** 48V 60W 1 Phase / DRP048V060W1B โ–ก ## Operating Mode ## ๏ฎ **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 0.90~1.00V for 48V 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 from 85-264Vac, 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 20A) 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) โ€“ 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 PSUโ€™s do not need to be connected to the Signal GND terminal. ## **Fig. 3 Redundant Operation Connection Diagram** *Vdrop will vary from 0.60V to 0.90V (Typical 0.65V) depending on the load current and surrounding air temperature ## ๏ฎ **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 25mV 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. **Fig. 4 Parallel Operation Connection Diagram** All parameters are specified at 25ยฐC ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (December 2018, Rev. 04)** 14 **TECHNICAL DATASHEET** ## **CliQ II DIN Rail Power Supply** 48V 60W 1 Phase / DRP048V060W1B โ–ก ## **Others** ## Delta RoHS Compliant ## **Restriction of the usage of hazardous substances** The European directive 2011/65/EU limits the maximum impurity level of homogeneous materials such as lead, mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical and electronic equipment. RoHS is the abbreviation for โ€œRestriction of the use of certain hazardous substances in electrical and electronic equipmentโ€. 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.
