Power supply components may degrade, or be damaged, when the power supply is continuously used outside the shaded region, refer to the graph shown in Fig. 1. If the output capacity is not reduced when the surrounding air temperature exceeds its specification as defined on Page 3 under “Environment”, the device will run into Over Temperature Protection. When activated, the output voltage will go into bouncing mode and will recover when the surrounding air temperature is lowered or the load is reduced as far as necessary to keep the device in working condition. In order for the device to function in the manner intended, it is also necessary to keep a safety distance as recommended in the safety instructions while the device is in operation. Depending on the surrounding air temperature and output load delivered by the power supply, the device can be very hot! If the device has to be mounted in any other orientation, please contact info@deltapsu.com for more details.

The device should be installed with input terminal block at the bottom. Each device is delivered ready to install. Mounting Dismounting Fig. 2.1 Mounting Fig. 2.2 Dismounting Snap on the DIN rail as shown in Fig. 2.1: 1. Tilt the unit upwards and insert it onto the DIN rail. 2. Push downwards until stopped. 3. Press against the bottom front side for locking. 4. Shake the unit slightly to ensure that it is secured. To uninstall, pull or slide down the latch with screw driver as shown in Fig. 2.2. Then slide the power supply unit (PSU) in the opposite direction, release the latch and pull out the power supply unit (PSU) from the rail. 7 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (February 2022, Rev. 06) TECHNICAL DATASHEET Sync DIN Rail Power Supply 24 V 30 W 1 Phase (NEC Class 2) / DRS-24V30W1AZ Safety Instructions • • • • • • • • ALWAYS switch mains of input power OFF before connecting and disconnecting the input voltage to the unit. If mains are not turned OFF, there is risk of explosion / severe damage. To guarantee sufficient convection cooling, keep a distance of 80 mm (3.14 inch) above and below the device as well as a lateral distance of 25 mm (0.98 inch) 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 the wires to the terminals! DO NOT insert any objects into the device. Dangerous voltages present for at least 5 minutes after disconnecting all sources of power. 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. 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 final steady state 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 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. 8 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (February 2022, Rev. 06) TECHNICAL DATASHEET Sync DIN Rail Power Supply 24 V 30 W 1 Phase (NEC Class 2) / DRS-24V30W1AZ Inrush Current Overload & Overcurrent Protections (Auto-Recovery) 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’s Overload (OLP) and Over current (OCP) Protections will be activated when output current (IO) exceeds its specification as defined on Page 3 under “Protections”. In such occurrence, 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. 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. 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.  50% duty cycle / 5 Hz to 100 Hz Over Temperature Protection (Auto-Recovery) 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. 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. Overvoltage Protection (Auto-Recovery) 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”. 9 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (February 2022, Rev. 06) TECHNICAL DATASHEET Sync DIN Rail Power Supply 24 V 30 W 1 Phase (NEC Class 2) / DRS-24V30W1AZ Operating Mode  Redundancy Operation 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 0.45~0.50 V for these 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 each power supply to 50% of rated load at any line voltage from 85-264 Vac, 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 right of above diagram. 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). *Vdrop will vary from 0.60 V to 0.90 V (Typical 0.65 V) depending on the load current and surrounding air temperature.  **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. 3 Redundant Operation Connection Diagram 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.
