Datasheet
**TXO 300 Series, 300 Watt** ## **AC/DC Power Supply** - **Industrial AC/DC power supplies for cost sensitive applications** - **I/O reinforced isolation 3000 VAC** - **Operating temperature range –20°C to +70°C** - **Protection class II prepared** - **Internal EN 55032 class B filter** - **Remote control** - **Short circuit, overvoltage and overload protection** - **Over temperature switch off** - **3-year product warranty** UL 62368-1 IEC 62368-1 The TXO 300 is a series of AC/DC open frame power supplies with 300 Watt and a 3000 VAC reinforced isolation system. Our TXO line specifically focuses on providing cost efficient industrial power supplies. High efficiency of up to 88% allows a compact design and an operating temperature range of –20°C to +50°C without derating, while going up to +70°C with load derating. They feature remote control, come with an active power factor correction and EMC characteristics dedicated for applications in industrial/automation and test & measurement fields. It makes the products an ideal solution for various industrial and cost sensitive applications. ## **Models** |**Order Code**|**Output Power**<br>**max.**|**Output Voltage**<br>**nom.**|**Output Current max.**<br>(Forced air cooling)|**Output Current max.**<br>(Natural convection)|**Efficiency**<br>**typ.**| |---|---|---|---|---|---| |**TXO 300-112-J**<br>**TXO 300-115-J**<br>**TXO 300-124-J**<br>**TXO 300-148-J**|300 W|12 VDC<br>15 VDC<br>24 VDC<br>48 VDC|25'000 mA<br>20'000 mA<br>12'500 mA<br>6'250 mA|15'000 mA<br>12'000 mA<br>8'340 mA<br>4'170 mA|88 %<br>88 %<br>88 %<br>88 %| ## **Options** |**on demand**|- Optional model with 36 VDC and 8'340 mA| |---|---| |(backorder with MOQ|| |non stocking item)|- Optional model with 56 VDC and 5'360 mA| Note - Total output power must not exceed 180 W (12/15 Vout models) or 200 W (other Vout models) when convection cooled **Page 1 / 5** **September 13, 2024** **www.tracopower.com** **TXO 300 Series, 300 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: 120 - 370 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|3'500 mW max.| ||- No load & Vin = 115 VAC|5'000 mW max.| |Input Current|- Full load & Vin = 230 VAC|2'000 mA max.| ||- Full load & Vin = 115 VAC|4'500 mA max.| |Input Inrush Current|- At 230 VAC|200 A max.| ||- At 115 VAC|100 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||5 A / 250 VAC(Internal Fuse in L)| |Recommended Input Fuse||5'000 mA(slow blow)| |||(The need of an external fuse has to be assessed| |||in the final application.)| ## **Output Specifications** Voltage Set Accuracy |Voltage Set Accuracy||±2% max.(main output)| |---|---|---| |||±3% max.(Standby output)| |||±6% max.(Fan output)| |Regulation|- Input Variation (Vmin - Vmax)|0.5% max.(incl. standby and fan output)| ||- Load Variation (10 - 100%)|3% max.(main output)| |||3% max.(Standby output)| |||10% max.(Fan output)| |Ripple and Noise||12 VDC model: 200 mVp-p max.| |(20 MHz Bandwidth)||15 VDC model: 220 mVp-p max.| |||24 VDC model: 240 mVp-p max.| |||48 VDC model: 480 mVp-p max.| |||36 VDC model: 360 mVp-p max.| |||56 VDC model: 560 mVp-pmax.| |Capacitive Load||12 VDC model: 20'000 µF max.| |||15 VDC model: 15'000 µF max.| |||24 VDC model: 4'000 µF max.| |||48 VDC model: 1'200 µF max.| |||36 VDC model: 1'800 µF max.| |||56 VDC model: 680µF max.| |Minimum Load||Not required| |Temperature Coefficient||±0.05 %/K max.| |Hold-up Time|- At 230 VAC|10 ms min.| ||- At 115 VAC|10 ms min.| |Start-up Time|- At 230 VAC|4'000 ms max.| ||- At 115 VAC|4'000 ms max.| |Start-upOvershoot Voltage||10% max.| |Short Circuit Protection||Continuous,Automatic recovery| |Output Current Limitation||110 - 180% of Iout max.| |Overvoltage Protection||110 - 170% of Vout nom.| |Transient Response|- Response Deviation|3% typ. / 5% max.(50% to 75% Load Step)| ||- Response Time|1'000 µs typ. / 2'000 µs max.(50% to 75%| |||Load Step)| All specifications valid at nominal voltage, resistive full load and +25°C after warm-up time, unless otherwise stated. **Page 2 / 5** **September 13, 2024** **www.tracopower.com** **TXO 300 Series, 300 Watt** |**Safety Specifications**||| |---|---|---| |Standards<br>- IT / Multimedia Equipment||EN 62368-1| |||IEC 62368-1| |||UL 62368-1| |- Certification Documents||www.tracopower.com/overview/txo300| |Protection Class||Class I & II(Prepared): Reinforced Insulation| |Pollution Degree||PD 2| |Over Voltage Category||OVC II| |**EMC Specifications**||| |EMI (Emissions)<br>- Conducted Emissions||EN 55032 class B(internal filter)| |||FCC 47 Part 15 class B(internal filter)| |- Radiated Emissions||EN 55032 class B(internal filter)| |||FCC 47 Part 15 class B(internal filter)| |- Harmonic Current Emissions||EN 61000-3-2, class A| |- Voltage Fluctuations & Flicker||EN 61000-3-3| |EMS (Immunity)||EN 55035(Multimedia)| |- Electrostatic Discharge|Air:|EN 61000-4-2, ±8 kV, perf. criteria A| ||Contact:|EN 61000-4-2, ±4 kV, perf. criteria A| |- RF Electromagnetic Field||EN 61000-4-3, 3 V/m, perf. criteria A| |- EFT (Burst) / Surge||EN 61000-4-4, ±1 kV, perf. criteria A| ||L to L:|EN 61000-4-5, ±1 kV, perf. criteria A| ||L to PE:|EN 61000-4-5, ±2 kV, perf. criteria A| |- Conducted RF Disturbances||EN 61000-4-6, 3 Vrms, perf. criteria A| |- PF Magnetic Field|Continuous:|EN 61000-4-8, 1 A/m, perf. criteria A| |- Voltage Dips & Interruptions|230 VAC / 50 Hz:|EN 61000-4-11| |||30%, 25 periods, perf. criteria A| |||>95%, 0.5 periods, perf. criteria A| |||>95%,250periods, perf. criteria B| |EMC / Environmental<br>- Certification Documents||www.tracopower.com/overview/txo300| |**General Specifications**||| |Relative Humidity||95% max.
