Datasheet
**AC/DC Power Supply** **TPI 300-M Series, 300 Watt** - **High power-density: 300 Watt in 4.6”x2.44” package (encased)** - **I/O isolation 3000 VAC rated for 250 VAC working voltage** - **Certification according to IEC/EN/UL 62368-1** - **Peak power operation up to 360 Watt for 5s** - **Operating temperature –40°C to 80°C** - **Active power factor correction >0.9** - **Operating up to 5000m altitude** - **High efficiency up to 93%** UL 62368-1 IEC 62368-1 - **Protection class II prepared** - **3-year product warranty** The TPI 300-M series is a set of encapsulated AC/DC power supplies in an encased package style. They feature a reinforced double I/O isolation (3000 VAC) system according to latest industrial safety standards. The excellent efficiency of up to 93% allows a high power-density and compact design (4.6” x 2.44”). The operating temperature range is –40°C to +80°C with derating above 50°C. In natural convection operation these power supplies deliver 180 Watt going up to 300 Watt with forced air cooling. Additionally, they can deliver 360 Watt peak power for 5s. The EMC characteristic is dedicated for applications in industrial and medical fields. High reliability is provided by using high quality components and an excellent thermal management making the TPI 300-M an ideal solution for industrial and medical devices and for demanding safety and 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 300-112-M**<br>**TPI 300-115-M**<br>**TPI 300-124-M**<br>**TPI 300-136-M**<br>**TPI 300-148-M**<br>**TPI 300-153-M**|300 W|12 VDC(10.8 - 13.2 VDC)<br>15 VDC(13.5 - 16.5 VDC)<br>24 VDC(21.6 - 26.4 VDC)<br>36 VDC(32.4 - 39.6 VDC)<br>48 VDC(43.2 - 52.8 VDC)<br>53 VDC(47.7 - 58.3 VDC)|25'000 mA<br>20'000 mA<br>12'500 mA<br>8'330 mA<br>6'250 mA<br>5'670 mA|30'000 mA<br>24'000 mA<br>15'000 mA<br>10'000 mA<br>7'500 mA<br>6'790 mA|91 %<br>92 %<br>93 %<br>93 %<br>93 %<br>93 %| ## **Options** **on demand** - Optional model with 18 VDC / 16'667 mA (backorder with MOQ non stocking item) - Optional model with 28 VDC / 10'710 mA **Page 1 / 6** **February 4, 2022** **www.tracopower.com** **TPI 300-M Series, 300 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|1'600 mA max.| ||- Full Load & Vin = 115 VAC|3'900 mA max.| |Power Consumption|- At no load|3'000 mW typ.| |Input Inrush Current|- At 230 VAC|70 A max.| ||- At 115 VAC|40 A max.| |Power Factor|- At 230 VAC|0.9 min.(Active Power Factor Correction)| ||- At 115 VAC|0.9 min.(Active Power Factor Correction)| |Input Protection||T 5 A / 250 VAC(Internal Fuse in L & N)| |Recommended Input Fuse||5'000 mA(slow blow)| |||(The need of an external fuse has to be assessed| |||in the final application.)| ## **Output Specifications** Output Voltage Adjustment |Output Voltage Adjustment||±10%(By trim potentiometer)| |---|---|---| |||Output power must not exceed rated power!| |Voltage Set Accuracy||±1% max.| |Regulation|- Input Variation (Vmin - Vmax)|0.2% max.| ||- Load Variation(0 - 100%)|0.5% max.| |Boost Power||Output Current peak: See model table| |||Peak power time: 5 s max.| |||Peak power duty cycle: 20% max.| |||Average operationpower: 50% of full load| |Ripple and Noise||12 VDC model: 150 mVp-p max.(w/ 1 µF X7R)| |(20 MHz Bandwidth)||15 VDC model: 180 mVp-p max.(w/ 1 µF X7R)| |||18 VDC model: 210 mVp-p max.(w/ 1 µF X7R)| |||24 VDC model: 270 mVp-p max.(w/ 1 µF X7R)| |||28 VDC model: 310 mVp-p max.(w/ 1 µF X7R)| |||36 VDC model: 390 mVp-p max.(w/ 1 µF X7R)| |||48 VDC model: 510 mVp-p max.(w/ 1 µF X7R)| |||53 VDC model: 540 mVp-pmax.
