Datasheet
**TXN 50 Series, 50 Watt** ## **AC/DC Industrial Power Supply** - **Compact metal case with screw terminal block** - **Universal input 90-264 VAC** - **High efficiency up to 86%** - **Compliance to EN 61000-3-2** - **Short circuit, overvoltage and overload protection** - **IEC/EN/UL 62368-1 safety approvals** - **3-year product warranty** UL 62368-1 IEC 62368-1 The new TXN line comprises a series of cost efficient, metal enclosed AC/DC power supplies and is designed for industrial applications. With a low-profile metal case and screw terminal block connection, they are easy to install in any equipment. The TXN power supplies are completely convection cooled. Internal EMC filter, high IO-isolation and wide temperature range qualify them for numerous industrial applications. These power supplies have universal input and comply with the latest industrial standard IEC/EN/UL 62368-1, European EMC standards and the Low Voltage Directive (LVD). ## **Models** |**Order Code**|**Output Power**<br>**max.**|**Output Voltage**<br>**nom.**(adjustable)|**Output Current**<br>**max.**|**Efficiency**<br>**typ.**| |---|---|---|---|---| |**TXN 50-103**<br>**TXN 50-105**<br>**TXN 50-112**<br>**TXN 50-115**<br>**TXN 50-124**<br>**TXN 50-148**|33 W|3.3 VDC(2.9 - 3.6 VDC)<br>5 VDC(4.5 - 5.5 VDC)<br>12 VDC(10.8 - 13.2 VDC)<br>15 VDC(13.5 - 16.5 VDC)<br>24 VDC(21.6 - 26.4 VDC)<br>48 VDC(44.0 - 52.0 VDC)|10'000 mA<br>10'000 mA<br>4'200 mA<br>3'400 mA<br>2'100 mA<br>1'100 mA|84 %<br>83 %<br>85 %<br>85 %<br>85 %<br>86 %| ||50 W|||| ## **Options** **on demand** (backorder with MOQ - Optional model with 36 VDC and 1'400 mA non stocking item) **Page 1 / 4** **September 3, 2024** **www.tracopower.com** **TXN 50 Series, 50 Watt** ## **Input Specifications** Input Voltage - AC Range Operational Range: 90 - 264 VAC (Full Range) Rated Range: 100 - 240 VAC (Full Range) - DC Range Operational Range: 140 - 340 VDC (Designed for, no certification) Polarity: +DC: L / –DC: N Input Frequency Operational Range: 47 - 63 Hz Certified: 50/60 Hz Power Consumption - No load & Vin = 230 VAC 1 W max. - No load & Vin = 115 VAC 1 W max.
