Datasheet
**TCI 500U Series, 500 Watt** ## **AC/DC Industrial Power Supply** - **Conduction cooled design approach** - **Fanless operation with up to 90% output power** - **Operating temperature range –30°C to +80°C** - **I/O reinforced isolation 4250 VAC** - **Over voltage category (OVC III)** - **High efficiency up to 92%** - **Operating up to 5000 m altitude** - **Internal EN 55032 class B filter** - **Protection class II prepared** - **3 year product warranty** UL 62368-1 IEC 62368-1 The TCI 500U is a 500 Watt conduction cooled AC/DC encased power supplies series with a 4250 VAC reinforced isolation system. Traco Power’s new TCI line focuses on maximizing the proficiency of conduction cooled systems as it offers superior temperature behavior when mounted on a metal chassis or baseplate. This way the TCI 500U can deliver up to 90% of the maximum output power without the need for a fan. Excellent efficiency of up to 92% allows the TCI series to operate from –30 to +50°C without derating, while going up to +80°C with either load derating or forced cooling. They also meet OVC III requirements and can operate at up to 5000 m altitude. Active power factor correction, EMC characteristics dedicated for applications in industrial/automation and test & measurement fields and high reliability make the new TCI line an ideal solution for any demanding industrial application. ## **Models** |**Order Code**|**Output Power**<br>**max.**|**Output Voltage**<br>**nom.**(adjustable)|**Output Current max.**<br>(Forced air cooling)|**Output Current max.**<br>(Conduction Cooling)|**Efficiency**<br>**typ.**| |---|---|---|---|---|---| |**TCI 500-112U-T**<br>**TCI 500-124U-T**<br>**TCI 500-148U-T**|500 W|12 VDC(11.4 - 12.6 VDC)<br>24 VDC(22.8 - 25.2 VDC)<br>48 VDC(45.6 - 50.4 VDC)|41'500 mA<br>20'800 mA<br>10'410 mA|37'500 mA<br>18'750 mA<br>9'375 mA|90 %<br>91 %<br>92 %| ## **Options** **TCI-AC1** - Optional Cable: www.tracopower.com/products/tci-ac1.pdf **TCI500-AUX** - Optional Cable: www.tracopower.com/products/tci500-aux.pdf **Page 1 / 5** **August 25, 2023** **www.tracopower.com** **TCI 500U 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: 127 - 370 VDC(Designed for, no certification)| |||Polarity: irrelevant| |Input Frequency||Operational Range: 47 - 63 Hz| |||Certified: 50/60 Hz| |Input Current|- Full Load & Vin = 230 VAC|3'150 mA max.| ||- Full Load & Vin = 115 VAC|6'300 mA max.| |Power Consumption|- No load & Vin = 230 VAC|500 mW max.(Ready to meet ErP directive)| ||- No load & Vin = 115 VAC|500 mW max.| |Input Inrush Current|- At 230 VAC|80 A max.| ||- At 115 VAC|40 A max.| |Power Factor|- At 230 VAC|0.94 min.(Active Power Factor Correction)| ||- At 115 VAC|0.94 min.(Active Power Factor Correction)| |Input Protection||T 10 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||±5%(By trim potentiometer)| |---|---|---| |||Output power must not exceed rated power!| |Voltage Set Accuracy||±2% max.| |Regulation|- Input Variation (Vmin - Vmax)|1% max.| ||- Load Variation(0 - 100%)|1% max.| |Ripple and Noise||12 VDC model: 160 mVp-p max.(w/ 0.1 µF ceramic || 47 µF KY)| |(20 MHz Bandwidth)||24 VDC model: 240 mVp-p max.(w/ 0.1 µF ceramic || 47 µF KY)| |||48 VDC model: 480 mVp-pmax.(w/ 0.1µF ceramic || 47µF KY)| |Capacitive Load||12 VDC model: 5'000 µF max.| |||24 VDC model: 2'500 µF max.| |||48 VDC model: 1'250µF max.| |Minimum Load||Not required| |Temperature Coefficient||±0.06 %/K max.(-30°C - 0°C)| |||±0.03 %/K max.(0°C - 50°C)| |Hold-up Time|- At 230 VAC|5 ms min.| ||- At 115 VAC|8 ms min.| |Start-up Time|- At 230 VAC|350 ms max.| ||- At 115 VAC|350 ms max.| |Short Circuit Protection||Continuous, Automatic recovery(Level 1, nom.)| |||Latch(Level 2,instantaneous high current)| |Output Current Limitation||113 - 161% of Iout max.| |Overvoltage Protection||111 - 130% of Vout nom.| |Transient Response|- Response Deviation|3% typ. / 5% max.(25% to 100% Load Step)| ||- Response Time|2'000 µs typ. / 3'000 µs max.(25% to 100%| |||Load Step)| ## **Safety Specifications** |Safety Standards|- IT / Multimedia Equipment|EN 62368-1| |---|---|---| |||IEC 62368-1| |||UL 62368-1| ||- Certification Documents|www.tracopower.com/overview/tci500u| |Protection Class||Class I(Prepared): Connection to PE| |Pollution Degree||PD 2| All specifications valid at nominal voltage, resistive full load and +25°C after warm-up time, unless otherwise stated. **Page 2 / 5** **August 25, 2023** **www.tracopower.com** **TCI 500U Series, 500 Watt** ## **EMC Specifications** EMI Emissions - Conducted Emissions - Radiated Emissions - Harmonic Current Emissions EMS Immunity - Electrostatic Discharge - RF Electromagnetic Field - EFT (Burst) / Surge - Conducted RF Disturbances - PF Magnetic Field - Voltage Dips & Interruptions EN 55032 class B (internal filter) EN 55032 class B (internal filter) EN 61000-3-2, class A EN 55035 (Multimedia) Air: EN 61000-4-2, ±8 kV, perf. criteria A Contact: EN 61000-4-2, ±4 kV, perf. criteria A EN 61000-4-3, 3 V/m, perf. criteria A 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 EN 61000-4-6, 3 Vrms, perf. criteria A Continuous: EN 61000-4-8, 1 A/m, perf. criteria A 230 VAC / 50 Hz: EN 61000-4-11 30%, 25 periods, perf. criteria A >95%, 250 periods, perf. criteria B 115 VAC / 60 Hz: 30%, 25 periods, perf. criteria A >95%, 250 periods, perf. criteria B ## **General Specifications** |Relative Humidity||95% max.
