瞬態電壓抑制器

The Gaia Converter LGDSI-75 Series designates an active power front end module designed to compley protect electronic systems. It embeds spike/transient suppression, EMI filtering, reverse polarity protection and inhibit functions as needed in typical Railway & high end Industrial products.

The LGDSI-75 delivers an adapted output voltage compliant with Gaia Converter DC/DC range of modules. This line of module is optimized to provide high efficiency up to 98% over the whole power range between 4W and 75W power.

Model:LGDSI75系列瞬態電壓抑制器 LGDSI75-Q-K

Gaia's LGDSI-75 Industrial Grade offer operating temperature ranges of -40 to +95°C with input ranges typically required for Transportation / OEM / Industrial applications:LGDSI75系列瞬態電壓抑制器 LGDSI75-Q-K

LGDSI-75-Q-K : 43-154 Vdc permanent; 165 Vdc / 1 s & 176 Vdc / 100 ms transients; 1.8kV / 50 μs spikes

The LGDSI-75 features 2 modes of operations as follow :

? Normal operation: Normal operation occurs when input bus line is in steady state permanent range. The LGDSI-75 is then operating in steady transparency state providing an output with a typical 1,5V drop-out voltage.

? Transient and spikes operation: The LGDSI-75 can sustain both: 
     - transient during 1s according or EN50155 requirements 
     - high spike levels up to 1.8kV with 5 Ohms impedance and 8.4kV with 100 Ohms impedance to meet input bus standards of EN50155.
