MTL SD07MXL-CDN SD07R series Surge Protection Device SPD

Here are the technical parameters of the MTL SD07MXL-CDN SD07R series Surge Protection Device (SPD):

1. **Rated Voltage**

    - The maximum continuous operating voltage \(U_{c}\) is the maximum RMS voltage (effective value) or DC voltage that can be continuously applied to the protection mode of the SPD. For the MTL SD07R series, the typical rated voltages are 150V and 275V.

2. **Discharge Current**

    - **Nominal Discharge Current** (\(I_{sn}\)): It is the peak value of the 8/20μs current wave flowing through the SPD. For the MTL SD07R series, the nominal discharge surge current is 3kA (8/20μs).

    - **Maximum Discharge Current** (\(I_{max}\)): The peak value of the 8/20μs current wave flowing through the SPD. For the MTL SD07R series, the discharge surge current is 20kA (8/20μs).

    - **Impulse Current** (\(I_{imp}\)): The ability to pass a 10/350μs lightning current wave, including two parameters: peak current \(I_{peak}\) and charge \(Q\). For the MTL SD07R series, only some specific models like SD150X and SD275X have an impulse current of 1.0kA (10/350μs).

3. **Voltage Protection Level** (\(U_{p}\))

    - Also known as the residual voltage, it is the voltage across the SPD when a current of a specified waveform and amplitude flows through the SPD after it operates. The voltage protection level of the MTL SD07R series is typically within a certain range depending on the specific model and test conditions.

4. **Response Time** (\(t_{A}\))

    - It mainly reflects the action sensitivity and breakdown time of the special protection components in the protector. For the MTL SD07R series SPDs, the response time is generally within the nanosecond level (10⁻⁹ s).

5. **Bandwidth**

    - The SD07R series has a bandwidth of 50MHz, which means it can effectively handle signals within this frequency range, making it suitable for high - speed data link applications.

6. **Operating Temperature**

    - The operating temperature range of the MTL SD07R series is - 40 °C to + 80 °C (- 40 °F to 176 °F), and the storage temperature range is also - 40 °C to + 80 °C (- 40 °F to 176 °F).

7. **Relative Humidity**

    - It can work in an environment with a relative humidity of 5% - 95% (non - condensing).

8. **Mounting Method**

    - The MTL SD07R series can be mounted on a T - beam DIN rail, which is 35 x 7.5 or 35 x 15mm (1.38” x 0.3” x 0.6”).

9. **Overload Fault Mode**

    - For the MTL SD07R series, \(I_{n}\)= 3kA, and the overload fault current of the SD150X and SD275X models is 9kA.

10. **Enclosure Flammability**

    - The enclosure of the MTL SD07R series has a flammability rating of UL94 V - 2.
