If mains are not turned OFF, there is risk of explosion / severe damage. To guarantee sufficient convection cooling, keep a distance of 50 mm (1.97 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! 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 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 (April 2021, Rev. 04) TECHNICAL DATASHEET Chrome DIN Rail Power Supply 24V 60W 1 Phase (Class II & NEC Class 2) / DRC-24V60W1A□ 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 10% to 100% of its rated current.  50% duty cycle / 5Hz to 100Hz 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, a minimum value of 16A B- or 8A C- characteristic breaker should be used. 9 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (April 2021, Rev. 04) TECHNICAL DATASHEET Chrome DIN Rail Power Supply 24V 60W 1 Phase (Class II & NEC Class 2) / DRC-24V60W1A□ Overload & Overcurrent Protections (Auto-Recovery) Overvoltage Protection (Latch Mode) 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. 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”. Power supply will latch, and require removal/re-application of input AC voltage in order to restart. Over Temperature Protection (Latch Mode) 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. 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. 10 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; or, when the operating temperature is beyond what is recommended in the de-rating graph, the OTP circuit will be activated. When activated, power supply will latch, until the surrounding air temperature drops to its normal operating temperature or the load is reduced as recommended in the de-rating graph. Removal/re-application of input AC voltage will then be required in order to restart. All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (April 2021, Rev. 04) TECHNICAL DATASHEET Chrome DIN Rail Power Supply 24V 60W 1 Phase (Class II & NEC Class 2) / DRC-24V60W1A□ Operating Mode  Redundant 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% of rated load at any line voltage, and set the PSU 1 and PSU 2 output voltage. Step 2. 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). **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 Fig. 4 Parallel Operation Connection Diagram *Vdrop will vary from 0.60V to 0.90V (Typical 0.65V) 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 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. 11 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (April 2021, Rev. 04) TECHNICAL DATASHEET Chrome DIN Rail Power Supply 24V 60W 1 Phase (Class II & NEC Class 2) / DRC-24V60W1A□ Fig. 5  DC Input Operation Connection Diagram DC Input Operation Step 1.
