If mains are not turned OFF, there is risk of explosion / severe damage. - **To guarantee sufficient convection cooling, keep a distance of 50mm above and below the device as well as a lateral distance of 20mm (for Vertical Mounting) or 50mm (for Horizontal Mounting) to other units.** - Note that the enclosure of the device can become very hot depending on the surrounding air temperature and load of the power supply. Risk of burns! - The main power must be turned off before connecting or disconnecting wires to the terminals! - DO NOT insert any objects into the unit. - Hazardous voltages may be present for up to 5 minutes after the input mains voltage is disconnected. Do not touch the unit during this time. - The power supplies unit should be installed in minimum IP54 rated enclosure. - The power supplies are built in units and must be installed in a cabinet or room (condensation free environment and indoor location) that is relatively free of conductive contaminants. All parameters are specified at 25°C ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (November 2018, Rev. 02)** 8 ## **TECHNICAL DATASHEET CliQ DIN Rail Power Supply** 24V 48W 1 Phase / DRP-24V48W1AZ ## **Functions** **Graph illustrating the Start-up Time, Rise Time, and Hold-up Time** ## Start-up Time The time required for the output voltage to reach 90% of its set value, after the input voltage is applied. ## Rise Time The time required for the output voltage to change from 10% to 90% of its set value. ## Hold-up Time Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time required for the output to reach 90% of its set value, after the input voltage is removed. All parameters are specified at 25°C ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (November 2018, Rev. 02)** 9 **TECHNICAL DATASHEET** ## **CliQ DIN Rail Power Supply** 24V 48W 1 Phase / DRP-24V48W1AZ ## Inrush Current 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. ## Dynamic Response The power supply output voltage will remains within ±5% of its steady state value, when subjected to a dynamic load from 10% to 100% of its rated current. ## Overload & Overcurrent Protections ## Overvoltage Protection 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 3 under “Protections”. The power supply’s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current exceeds 105~180% 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 “Hiccup mode” (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. ## Over Temperature Protection As mentioned, 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 condition at 100% load, the power supply will run into OTP when the surrounding air temperature is >75°C. When activated, the output voltage will go into latch-off mode until the component temperature cools down and the AC power is recycled. Additionally, if the IO is <105-180% but >100% for a prolong period of time (depending on the load), the Over Temperature Protection (OTP) will be activated due to high temperature on critical components. The power supply will then go into “Latch-off mode” until the PSU cools down and the AC power is recycled. ## Short Circuit Protection 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. All parameters are specified at 25°C ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (November 2018, Rev. 02)** 10 **TECHNICAL DATASHEET** ## **CliQ DIN Rail Power Supply** 24V 48W 1 Phase / DRP-24V48W1AZ ## Operating Mode ##  **Redundancy Operation** In order to ensure proper redundancy operation for the power supply unit (PSU), ensure that the output voltage difference between the two units is kept at 0.45~0.50V for 24V supplies. Follow simple steps given below to verify: ## **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, connect the power supply to 50% load and set the PSU 1 and PSU 2 output voltage. ## **Step 2.** **Fig. 2 Redundancy / Parallel Operation Connection Diagram** Connect the right DRR module, 20A as per the system requirement to the power supply units PSU 1 and PSU 2 at Vin 1 & Vin 2 respectively. ## **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). ##  **Parallel Operation** These DRR modules can also be used for Parallel function in order to increase the output power by N+1 (e.g. 2.5A + 2.5A = 5A or 2.5A + 2.5A + 2.5A = 7.5A) or current sharing, and thus increasing the power supply and system reliability. Though the DRP-24V48W1AZ is not designed for current sharing, a good current sharing between two power supplies can be achieved by following simple steps as below (Refer to Fig. 2 for the Connection Diagram). ## **Step 1.** Set output load condition for both supplies at 50% and measure the output voltages. ## **Step 3.** Connect PSU 1 and PSU 2 with the DRR-20A module and measure at Vin 1 & Vin 2 to verify the voltage difference. Ensure the voltages are within ±25mV. ## **Step 2.** Adjust output voltages to the same level or within ±25mV difference. ## **Step 4.** Output voltage from DRR module Vout 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. All parameters are specified at 25°C ambient and AC input unless otherwise indicated. **www.DeltaPSU.com (November 2018, Rev. 02)** 11 **TECHNICAL DATASHEET** ## **CliQ DIN Rail Power Supply** 24V 48W 1 Phase / DRP-24V48W1AZ ## **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.
