A high efficiency of 92% allows the TXO 500 to deliver 290 Watt up to +50°C with convection cooling and 500 Watt up to +50°C with forced air cooling, while going up to +70°C with derating. It comes with an active power factor correction and EMC characteristics dedicated for applications in industrial/automation and test & measurement fields. The TXO 500 also features auxiliary functions like remote on/off, sense function and standby power making these power supplies an ideal solution for various industrial and cost sensitive applications. ## **Models** |**Order Code**|**Output Power**|**Output Power**|**Output Voltage**|**Output Current max.**|**Output Current max.**|**Efficiency**| |---|---|---|---|---|---|---| |||**max.**|**nom.**(adjustable)|(Forced air cooling)|(Natural convection)|**typ.**| |**TXO 500-112-J**||450 W|12 VDC(11.04 - 12.96 VDC)|37'500 mA|20'000 mA|89 %| |**TXO 500-115-J**|||15 VDC(13.8 - 16.2 VDC)|30'000 mA|16'000 mA|89 %| |**TXO 500-124-J**||500 W|24 VDC(22.8 - 25.2 VDC)|20'840 mA|12'080 mA|91 %| |**TXO 500-148-J**|||48 VDC(45.6 - 50.4 VDC)|10'420 mA|6'040 mA|92 %| |**Options**||||||| |**TXO 500-AUX**||- Optional Cable:www.tracopower.com/overview/txo500-aux||||| |**TXO 500-DC**||- Optional Cable:www.tracopower.com/overview/txo500-dc||||| |**on demand**||- Optional model with 36 VDC and 13'890 mA||||| |(backorder with MOQ||||||| |non stocking item)||- Optional model with 56 VDC and 8'930 mA||||| Note - Total output power must not exceed 240 W (12/15 Vout models) or 290 W (other Vout models) when convection cooled **Page 1 / 5** **December 10, 2024** **www.tracopower.com** **TXO 500 Series, 500 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: irrelevant| |Input Frequency||Operational Range: 47 - 63 Hz| |||Certified: 50/60 Hz| |Power Consumption|- No load & Vin = 230 VAC|8.5 W max.| ||- No load & Vin = 115 VAC|8.5 W max.| |Input Current|- Full load & Vin = 230 VAC|2'600 mA max.| ||- Full load & Vin = 115 VAC|5'000 mA max.| |Input Inrush Current|- At 230 VAC|110 A max.| ||- At 115 VAC|65 A max.| |Power Factor|- At 230 VAC|0.9 min.(Active Power Factor Correction)| ||- At 115 VAC|0.92 min.(Active Power Factor Correction)| |Input Protection||T 8.0 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%(12 & 15 Vout models)| |---|---|---| |||±5%(other Vout models)| |||(By trim potentiometer)| |||Outputpower must not exceed ratedpower!| |Voltage Set Accuracy||±1.5% max.(main output)| |||±5% max.(Standby output)| |||±4% max.(Fan output)| |Regulation|- Input Variation (Vmin - Vmax)|0.5% max.| ||- Load Variation (10 - 100%)|3% max.(Main Output)| |||5% max.(Fan Output & StandbyOutput)| |Ripple and Noise||12 VDC model: 200 mVp-p max.(w/ 22 µF ELCO || 0.1 µF| |(20 MHz Bandwidth)||MLCC)| |||15 VDC model: 240 mVp-p max.(w/ 22 µF ELCO || 0.1 µF| |||MLCC)| |||24 VDC model: 240 mVp-p max.(w/ 22 µF ELCO || 0.1 µF| |||MLCC)| |||36 VDC model: 360 mVp-p max.(w/ 22 µF ELCO || 0.1 µF| |||MLCC)| |||48 VDC model: 480 mVp-p max.(w/ 22 µF ELCO || 0.1 µF| |||MLCC)| |||56 VDC model: 560 mVp-p max.(w/ 22 µF ELCO || 0.1 µF| |||MLCC)| |Capacitive Load||12 VDC model: 30'000 µF max.| |||15 VDC model: 18'000 µF max.| |||24 VDC model: 8'000 µF max.| |||36 VDC model: 5'000 µF max.| |||48 VDC model: 2'100 µF max.| |||56 VDC model: 1'800µF 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|2'000 ms max.| ||- At 115 VAC|3'500 ms max.| |Start-upOvershoot Voltage||10% max.| |Short Circuit Protection||Continuous,Automatic recovery| All specifications valid at 230 VAC, resistive full load and +25°C after warm-up time, unless otherwise stated. **Page 2 / 5** **December 10, 2024** **www.tracopower.com** **TXO 500 Series, 500 Watt** |Output Current Limitation||110 - 200% of Iout max.| |---|---|---| |||(Main Output)| |||110 - 350% of Iout max.| |||(Fan Output & StandbyOutput)| |Overvoltage Protection||105 - 150% of Vout nom.| |||(Main Output - Automatic recovery)| |||105 - 180% of Vout nom.| |||(Fan Output & StandbyOutput - Latch Off)| |Transient Response
