If the output capacity is not reduced when the surrounding air temperature >55°C, the device may run into Over Temperature Protection. When activated, the output voltage will go into latch-off mode and recoverable by AC power recycle. In order for the device to function in the manner intended, it is also necessary to keep a safety distance of 25mm with adjacent 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 orientation, please do not hesitate to contact [email protected] for more details. TECHNICAL DATASHEET Chrome DIN Rail Power Supply 12V 30W 1 Phase (Class II & NEC Class 2) / DRC-12V30W1AZ Output De-rating VS. Input Voltage No output power de-rating across the entire input voltage range Assembly & Installation The power supply unit (PSU) can be mounted on 35mm DIN rails in accordance with EN60715. 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. 7 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. All parameters are specified at 25°C ambient unless otherwise noted. www.DeltaPSU.com (August 2013, Rev. 00) TECHNICAL DATASHEET Chrome DIN Rail Power Supply 12V 30W 1 Phase (Class II & NEC Class 2) / DRC-12V30W1AZ 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 above and below the device as well as a lateral distance of 25mm 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 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. 8 All parameters are specified at 25°C ambient unless otherwise noted. www.DeltaPSU.com (August 2013, Rev. 00) TECHNICAL DATASHEET Chrome DIN Rail Power Supply 12V 30W 1 Phase (Class II & NEC Class 2) / DRC-12V30W1AZ Inrush Current Overload & Overcurrent Protections 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 >130% 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. It is not recommended to prolong the duration of IO when it is <130% but >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. Over Temperature Protection As mentioned above, 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 latch-off mode until the component temperature cools down and the AC power is recycled. Short Circuit Protection Overvoltage 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. 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 unless otherwise noted. www.DeltaPSU.com (August 2013, Rev. 00) TECHNICAL DATASHEET Chrome DIN Rail Power Supply 12V 30W 1 Phase (Class II & NEC Class 2) / DRC-12V30W1AZ 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.
