**RIA 12 Filter** **TFI 150, 150 Watt** - **Clamps over voltage transients (up to 385 VDC) at 168 VDC** - **Universal use: Can be used with** - **any DC/DC converter** - **Complies with RIA12, NF F 01-510 Surge susceptibilities** - **Wide input voltage range: 43 – 160 VDC** - **Brownout voltage 36 VDC min.** - **Operating temperature range** - **-40 to +95°C** - **3-year product warranty** The new TFI 150 is a surge filter which comes in a compact 1.6” x 1” plastic package. Placed in front of any DC/DC converter the TFI clamps momentary over-voltage transients to a safe value in order to protect the DC/DC converter from being damaged. During normal operation the output voltage follows the input voltage (Vout = Vin – 2 VDC typ.) up to the point of 168 VDC where the voltage is actively clamped. Whereas the transients defined within the EN 50155 (up to 154 VDC) are covered by the wide input range of dedicated railway converters the TFI handles the stricter definition laid-out in the RIA12 standard which allows transients of up to 20ms at 385 VDC. This level of protection is specifically required in railway applications where high voltage transients are expected but can also be used for 72, 96 and 110 VDC battery systems in railway applications. ## **Models** |**Order code**|**Input voltage**|**Power max.**| |---|---|---| |**TFI 150**|43 – 160 VDC|150 W| **Page 1 of 4** **www.tracopower.com** **TFI 150, 150 Watt** ## ~~**Input Specifications**~~ |Start-up Voltage||30 VDC max.| |---|---|---| |Transient Voltage|– 1 s max.|165 VDC max.| ||– 100 ms max.|176 VDC max.| ||– 20 ms max.|385 VDC max.| |Brownout||36 VDC min.| |~~**Output Specifications**~~||| |Output Voltage||Vin - 2 VDC typ. / Vin - 1 VDC max.| |Clamping Voltage|– Input Transient Voltage Mode|168 VDC typ.| |~~**General Specifications**~~||| |Standards||RIA 12 Surge Susceptibility| |||NF F 01-510 Surge Susceptibility| |Case Material||Non-conductive black plastic| |Base Material||Non-conductive black plastic| |Potting Material||Silicone(UL94 V-0)| |Weight||22 g| |Temperature ranges|– Operating (with derating)|–40°C to+95°C| ||– Case Temperature|+105°C max.| ||– Storage Temperature|–55°C to +125°C| |Relative Humidity||95% max.(non condensing)| |Thermal Shock||MIL-STD-810F| |Vibration||MIL-STD-810F| ## ~~**Characeristic Curves**~~ **==> picture [74 x 7] intentionally omitted <==** **----- Start of picture text -----**<br> Transient Function<br>**----- End of picture text -----**<br> All specifications valid at nominal input voltage, full load and +25°C after warm-up time unless otherwise stated. **Page 2 of 4** **www.tracopower.com** **TFI 150, 150 Watt** ## ~~**Possible Application**~~ **==> picture [497 x 111] intentionally omitted <==** **----- Start of picture text -----**<br> + +Vin +Vout<br>EMS RIA 12 EMI Cout<br>Input DC/DC Load<br>Filter* Filter Filter*<br>– –Vin –Vout<br>**----- End of picture text -----**<br> Schematic for typical application **==> picture [507 x 133] intentionally omitted <==** **----- Start of picture text -----**<br> Input Surge Voltage<br>385 V max.<br>Surge Voltage Clamping Voltage<br>+ +Vin +Vout<br>Clamping Voltage<br>RIA 12 168 V typ.<br>Input DC/DC Load<br>Filter<br>– –Vin –Vout<br>20 ms max.<br>**----- End of picture text -----**<br> Input Surge Voltage vs. Clamping Voltage The RIA 12 Filter clamps over-voltage to a safe value in order to protect the power module from damaging. *Optional, depending on DC/DC converter.
