Datasheet
DRB15-100 Series ## 15W - 100W DIN Rail Mount Single Phase Power Supplies https://product.tdk.com/en/power/drb www.emea.lambda.tdk.com/drb The DRB series supports the growing trend for simple and economically priced DIN power supplies for industrial and process control applications. The series combines low cost, reliability and compact dimensions with energy saving efficiencies of up to 91%. Conservatively rated electrolytic capacitor temperatures offer improved field life-times of up to 10 years. Available in four power levels, 15W, 30W, 50W, 100W, the series provides a choice of 5, 12, 15, 24 and 48V outputs. UL1310 Class 2 models and Class 1 Div 2 (ISA 12.12.01) certifications are available. |**Features**|**Benefits**| |---|---| |• High Efficiency, up to 91%|• Lowers Operating Costs and Improves Thermal Performance| |• Narrow Case Widths|• Increases Available Space on the DIN Rail| |• Curve B Radiated and Conducted EMI|• Reduced Electrical Noise in the System| |• Low No Load Power Draw|• Saves Energy| |• UL1310 Class 2 Compliant Models|• Suitable for Building Automation requiring NEC Class 2| |• Class 1 Div 2 Compliance|• For Use in Explosive Atmospheres| |**Model Selector**|**Model Selector**|||||||| |---|---|---|---|---|---|---|---|---| ||Output|Adjustment|Maximum|Maximum|Ripple|Overvoltage|Efficiency|| |Model|Voltage|Range|Current|Power|& Noise|Protection|(%)|UL1310| ||(V)|(V)|(A)|(W)|(mV)|(V)|(115/230Vac)|Class 2| |DRB50-5-1|5|5 - 5.5|6|30|30|5.75 - 6.75|79 / 80|No| |DRB30-12-1|12|12 - 15|2.5|30|40|15.96 - 18.72|86 /88|Yes| |DRB50-12-1|12|12 - 15|3.4|51*|20|15.96 - 18.72|88 / 90|Yes| |DRB50-15-1|15|12 - 15|3.4|51*|20|15.96 - 18.72|88 / 90|Yes| |DRB15-24-1|24|24 - 28|0.63|15.1|20|30 - 33.6|87 / 90|Yes| |DRB30-24-1|24|24 - 28|1.25|30|30|30 - 33.6|88 / 90|Yes| |DRB50-24-1|24|24 - 28|2.1|50.4|30|30 - 33.6|88 / 90|Yes| |DRB100-24-1|24|24 - 28|4.2|100.8|30|30 - 33.6|90 / 91|No| |DRB50-48-1|48|48 - 52.8|1.05|50.4|40|53.76 - 68.16|90 / 91|Yes| * Maximum power is 51W at 15V output, 40.8W when set at 12V output DRB15-100 Series 1 ## **Specifications** |Model||DRB15|DRB30<br>DRB50|DRB100| |---|---|---|---|---| |**Input**||||| |AC Input Voltage Range (Operating)|Vac||85 - 265|| |Nominal Input Voltage Range|Vac||100 - 240 (Note: Safety certified for 90 - 264Vac only)|| |DC Input Voltage Range(1)|Vdc||120 - 373 (Note: Safety certified for AC input only)|| |Input Surge Voltage|-||Withstands 300Vac for 5 seconds|| |Input Frequency|Hz||47 - 63 (Note: Safety certified for 50/60Hz only)|| |Input Current (110/230Vac)|A|0.27 / 0.17|0.55 / 0.33<br>0.9 / 0.55|1.2 / 0.6| |Inrush Current (Cold Start)|A|35|40<br>50|40| |Leakage Current (240Vac)|mA|<1.5|<1.5<br><0.55|<1.5| |Power Factor (110/230Vac)|-|0.55 / 0.42|0.56 / 0.46<br>0.6 / 0.5|0.98 0.93| |Harmonic Compliance|-||Meets EN61000-3-2 Class A|| |No Load Power Consumption|W|<0.3|<0.3<br><0.3|<0.5| |Hold Up Time (230Vac input)|ms||>20|| |Efficiency|-||See model selector table|| |Average Efficiency (230Vac)|%|88|87 / 89<br>87 / 88|87| |Conducted & Radiated EMI|-||EN55011-B, EN55032-B, VCCI-B, FCC-B|| |Immunity|-||See immunity table|| |Safety Agency Certifications and Markings|-|IEC/EN/CSA/UL62368-1, 60950-1, BIS IS 13252(Part 1) (24V models only) , UL508 Listed, UL1310 Class 2||| |||(see model selector), Class 1 Div 2, Group A, B, C, D (ISA 12.12.01), CE Mark and UKCA Mark||| ## **Immunity** |Test|Standard|Test Level|Criteria|| |---|---|---|---|---| |ESD|EN61000-4-2|4|A|-| |Radiated Susceptibility|EN61000-4-3|3|A|-| |Electrical Fast Transient Burst|EN61000-4-4|4|A|-| |Surge|EN61000-4-5|3|A|-| |Conducted Susceptibility|EN61000-4-6|3|A|-| |Magnetic fields|EN61000-4-8|4|A|-| |||0% for 1 cycle|A|-| |Voltage dips<br>and input interruptions|EN61000-4-11|40% for 10/12 cycles<br>70% for 25/30 cycles|B<br>B|-<br>-| |||80% for 250/300 cycles|80% for 250/300 cycles<br>B|-| |SEMI F47 Line Dip|SEMI F47|-|-|> 200Vac input| ## **Output Temperature Derating** ## **Output Temperature Derating** **==> picture [30 x 8] intentionally omitted <==** **----- Start of picture text -----**<br> DRB15<br>**----- End of picture text -----**<br> **==> picture [103 x 9] intentionally omitted <==** **----- Start of picture text -----**<br> DRB30, DRB50, DRB100<br>**----- End of picture text -----**<br> DRB15-100 Series 2 **==> picture [516 x 34] intentionally omitted <==** |**Specifcations**|**Specifcations**|**Specifcations**|**Specifcations**|**Specifcations**|**Specifcations**| |---|---|---|---|---|---| |Model<br>DRB15|||DRB30|DRB50|DRB100| |**Output**|||||| |Output Voltage Adjustment|V|See model selector|||| |Switching Frequency|kHz|100 (Fixed)|100 (Fixed)|75 - 170 (Variable)|100 - 150 (Variable)| |Line Regulation|mV|5V: 50, 12-15V: 150, 24V: 240, 48V: 480|||| |Load Regulation|mV|5V: 50, 12-15V: 150, 24V: 240, 48V: 480|||| |Ripple & Noise (max) (typ)<br>|mV|See model selector|||| |Temperature Coeffcient|%/°C|<±0.02|||| |Minimum Load|-|No minimum load required|||| |Overcurrent Protection|-|Hiccup with auto recovery|||| |Overvoltage Protection|V|See model selector.
