If the output capacity is not reduced when the surrounding air temperature >55°C, the device will run into Over Temperature Protection. When activated, power supply will latch off, until the surrounding air temperature is lowered or the load is reduced as far as necessary to keep the device in working condition, and require removal/re-application of input AC voltage in order to restart. In order for the device to function in the manner intended, it is also necessary to keep a safety distance of 50mm (1.97 inch) above and below the device as well as a lateral distance of 25mm (0.98 inch) to other units 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 please contact orientation, [email protected] 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 (April 2016, Rev. 02) TECHNICAL DATASHEET Chrome DIN Rail Power Supply 24V 91.2W 1 Phase (Class II & NEC Class 2) / DRC-24V100W1A□ 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 50mm (1.97 inch) above and below the device as well as a lateral distance of 25mm (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 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 (April 2016, Rev. 02) TECHNICAL DATASHEET Chrome DIN Rail Power Supply 24V 91.2W 1 Phase (Class II & NEC Class 2) / DRC-24V100W1A□ 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 is 3.8A IO (Max load) < 5.7A. In such occurrence, the VO will start to droop and once the output voltage is below 13Vdc typ., 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. 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. Additionally, if the IO is >102~108% 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 mode” until the PSU cools down and the AC power is recycled. Over Temperature Protection (Latch Mode) 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 off, 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. Short Circuit Protection (Auto-Recovery) Overvoltage Protection (Latch Mode) 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 off, and require removal/re-application of input AC voltage in order to restart. 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”. The power supply will return to normal operation after the short circuit is removed. The power supply should be latch. 9 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (April 2016, Rev. 02) TECHNICAL DATASHEET Chrome DIN Rail Power Supply 24V 91.2W 1 Phase (Class II & NEC Class 2) / DRC-24V100W1A□ Operating Mode Redundant 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 0.45~0.50V for these 24V 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 85-264Vac, and set the PSU 1 and PSU 2 output voltage. Fig. 3 Redundancy Operation Connection Diagram 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. 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 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.

RoHS is the abbreviation for “Restriction of the use of certain hazardous substances in electrical and electronic equipment”. This product conforms to this standard. 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. 11 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (April 2016, Rev. 02)
