Datasheet
**TPI 50A-J Series, 50 Watt** ## **AC/DC Industrial Power Supply** - **50 Watt open frame power supplies in a 3" x 1.5" package** - **Compact and cost efficient design** - **Peak power function up to 140%** - **I/O reinforced isolation 3000 VAC** - **Operating temperature range –40°C to +85°C** - **No load input power <0.3W (acc. ErP directive)** - **High efficiency up to 93%** - **Internal EN 55032 class B filter** - **Protection class II prepared** - **3 year product warranty** UL 62368-1 IEC 62368-1 The TPI 50A-J is a 50 Watt AC/DC open frame power supplies series with a 3000 VAC reinforced isolation system. Our TPI line specifically focuses on providing cost efficient industrial power supplies in compact designs. This series offers a peak power function which enables the unit to deliver up to 140% of the rated power for up to 5 seconds. Excellent efficiency of up to 93% allows a compact design and an operating temperature range (natural convection) of –40°C to +60°C without derating, while going up to +85°C with either load derating or forced cooling. They are designed to meet the ErP directive (< 0.3 W no load power consumption) and come with an EMC characteristics dedicated for applications in industrial/automation and test & measurement fields. High reliability is provided by use of industrial high-quality grade components and an excellent thermal management. It makes the TPI 50A-J an ideal solution for any demanding industrial devices or space critical applications. ## **Models** |**Order Code**|**Output Power**<br>**max.**|**Output Voltage**<br>**nom.**(adjustable)|**Output Current**<br>**max.**|**Output Current**<br>**peak**|**Efficiency**<br>**typ.**| |---|---|---|---|---|---| |**TPI 50-105A-J**<br>**TPI 50-112A-J**<br>**TPI 50-115A-J**<br>**TPI 50-124A-J**<br>**TPI 50-136A-J**<br>**TPI 50-148A-J**<br>**TPI 50-153A-J**|40 W|5 VDC(4.5 - 5.5 VDC)<br>12 VDC(9.6 - 13.2 VDC)<br>15 VDC(13.5 - 16.5 VDC)<br>24 VDC(19.2 - 26.4 VDC)<br>36 VDC(28.8 - 39.6 VDC)<br>48 VDC(38.4 - 52.8 VDC)<br>53 VDC(42.4 - 58.3 VDC)|8'000 mA<br>4'170 mA<br>3'340 mA<br>2'085 mA<br>1'390 mA<br>1'045 mA<br>950 mA|11'200 mA<br>5'835 mA<br>4'670 mA<br>2'920 mA<br>1'945 mA<br>1'460 mA<br>1'325 mA|91 %<br>93 %<br>93 %<br>93 %<br>92 %<br>92 %<br>92 %| ||50 W||||| ## **Options** **on demand** - Optional model with 7.5 VDC / 6'670 mA (backorder with MOQ - Optional model with 9 VDC / 5'560 mA non stocking item) - Optional model with 18 VDC / 2'780 mA **Page 1 / 5** **March 11, 2022** **www.tracopower.com** **TPI 50A-J Series, 50 Watt** ## **Input Specifications** |Input Voltage|- AC Range|Operational Range: 85 - 264 VAC(Full Range)| |---|---|---| |||Rated Range: 100 - 240 VAC(Full Range)| ||- DC Range|Operational Range: 120 - 370 VDC(Designed for, no certification)| |||Polarity: +DC: L / –DC: N| |Input Frequency||47 - 63 Hz| |Input Current|- Full Load & Vin = 230 VAC|800 mA max.| ||- Full Load & Vin = 115 VAC|1'300 mA max.| |Power Consumption|- At no load|150 mW max.
