Datasheet
**AC/DC Medical Power Supply** **TPP 450 Series, 450 Watt** - **High power density 3" x 5.8" encased medical power supply** - **450 Watt up to 65°C without derating, 320 Watt fanless operation without derating up to 50°C** - **Medical certification to IEC/EN/ES 60601-1 edition 3.2 for 2 x MOPP** - **EMC compliance to IEC/EN 60601-1-2 4th edition** - **Risk management process according to ISO 14971 incl. risk management file** - **Acceptance criteria for electronic assemblies acc. to IPC-A-610 class 3** - **Isolation (4000 VAC) and leakage current (<100 µA) rated for BF applications** - **Standard features: 5 V standby output 12 V fan output, Remote On/Off, Power Good Signal, variable fan speed** - **Operating up to 5000 m altitude** - **5-year product warranty** ES 60601-1 IEC 60601-1 UL 62368-1 IEC 62368-1 The TPP 450 Series of 450 Watt AC/DC power supplies feature a reinforced double I/O isolation system according to latest medical safety standards (60601-1 edition 3.2, 2 x MOPP). The earth leakage current is below 100 µA what makes the units suitable for BF (body floating) applications. The excellent efficiency of up to 94% allows a high power density for the standard 3" x 5" packaging format. Fanless operation power is 320W up to +50°C and 450W at +65°C with fan. Thus you can power your medical device in a quiet and hygienic way as you don’t need to run a fan to cool down the power supply. High reliability is provided by use of industrial quality grade components and an excellent thermal management. It makes the products an ideal solution for medical devices and for demanding safety and space critical applications. |**Order Code**|**Output Power**<br>**max.**|**Output Voltage**<br>**nom.**(adjustable)|**Output Current**<br>**max.**|**Efficiency**<br>**typ.**| |---|---|---|---|---| |**TPP 450-112-M**<br>**TPP 450-115-M**<br>**TPP 450-124-M**<br>**TPP 450-128-M**<br>**TPP 450-136-M**<br>**TPP 450-148-M**<br>**TPP 450-153-M**|450 W|12 VDC(11.0 - 13.0 VDC)<br>15 VDC(13.8 - 16.2 VDC)<br>24 VDC(22.1 - 25.9 VDC)<br>28 VDC(25.8 - 30.2 VDC)<br>36 VDC(33.1 - 38.9 VDC)<br>48 VDC(44.2 - 51.8 VDC)<br>53 VDC(48.8 - 57.2 VDC)|37'500 mA<br>30'000 mA<br>18'750 mA<br>16'100 mA<br>12'500 mA<br>9'400 mA<br>8'550 mA|91 %<br>92 %<br>93 %<br>93 %<br>93 %<br>94 %<br>94 %| ## **Options** **TPP 450-AUX1** - Optional Cable for auxiliary connection (2 x 4 pin): www.tracopower.com/overview/tpp450-aux1 **on demand** (backorder with MOQ - Optional version with fan on top non stocking item) **Page 1 / 6** **April 16, 2026** **www.tracopower.com** **TPP 450 Series, 450 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||Operational Range: 47 - 440 Hz| |||Certified: 50/60 Hz| |Power Consumption|- No load & Vin = 230 VAC|1'050 mW max.| ||- No load & Vin = 115 VAC|1'450 mW max.| |Input Current|- Full load & Vin = 230 VAC|2'400 mA max.| ||- Full load & Vin = 115 VAC|5'800 mA max.| |Input Inrush Current|- At 230 VAC|100 A max.| ||- At 115 VAC|55 A max.| |Power Factor|- At 230 VAC|0.95 min.(Active Power Factor Correction)| ||- At 115 VAC|0.95 min.(Active Power Factor Correction)| |Input Protection||T 6.3 A / 250 VAC(Internal Fuse in L & N)| |Recommended Input Fuse||(The need of an external fuse has to be assessed| |||in the final application.)| ## **Output Specifications** |Output Voltage Adjustment||±8%(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.| |Ripple and Noise||12 VDC model: 250 mVp-p typ.(w/ 1 µF X7R)| |(20 MHz Bandwidth)||15 VDC model: 300 mVp-p typ.(w/ 1 µF X7R)| |||24 VDC model: 240 mVp-p typ.(w/ 1 µF X7R)| |||28 VDC model: 280 mVp-p typ.(w/ 1 µF X7R)| |||36 VDC model: 360 mVp-p typ.(w/ 1 µF X7R)| |||48 VDC model: 480 mVp-p typ.(w/ 1 µF X7R)| |||53 VDC model: 530 mVp-ptyp.
