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, power supply will latch, 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 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 slightly upwards and put 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. Safety Instructions • • • • • • • • 10 ALWAYS switch mains of input power OFF before connecting and disconnecting the input voltage to the device. If mains are not turned OFF, there is risk of explosion / severe damage. To guarantee sufficient convection cooling, keep a distance of > 40 mm (1.57 inch) above and > 20 mm (0.79 inch) below the device as well as a lateral distance of > 15 mm (0.59 inch) to other units. In case the adjacent device is a heat source, the lateral distance will be > 25 mm (0.98 inch). Note that the enclosure of the device can become very hot depending on the surrounding air temperature and output load connected to the device. 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. All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (November 2021, Rev. 04) TECHNICAL DATASHEET Sync DIN Rail Power Supply 12 V 50 W 1 Phase (NEC Class 2) / DRS-12V50W1N□ 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. 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 0% to 100% of its rated current. 11  50% duty cycle / 5 Hz to 1 KHz All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (November 2021, Rev. 04) TECHNICAL DATASHEET Sync DIN Rail Power Supply 12 V 50 W 1 Phase (NEC Class 2) / DRS-12V50W1N□ Overload & Overcurrent Protections (Auto-Recovery) Overvoltage Protection (Latch Mode) The power supply’s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current is about 4.5 A typ. When this occurs, the VO will start to droop (refer to Ⓐ below). Once the output voltage is below about 7 Vdc typ., the power supply will start to operate in “Hiccup mode” (AutoRecovery mode). The power supply will recover once the fault condition of the OCP is removed and output current 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. The power supply should be latch. Over Temperature Protection (Latch Mode) Short Circuit Protection (Auto-Recovery) 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. 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. External Input Protection Device The unit is protected with internal fuse (not replaceable) at L pin and it has been tested and approved on 20 A (UL) and 16 A (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 20 A B- or 13 A Ccharacteristic breaker should be used. 12 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (November 2021, Rev. 04) TECHNICAL DATASHEET Sync DIN Rail Power Supply 12 V 50 W 1 Phase (NEC Class 2) / DRS-12V50W1N□ Operating Mode  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.
