瞬態(tài)電壓抑制器是一種能夠在電路中保護(hù)電子設(shè)備免受電壓過(guò)高的影響的元器件。其主要原理是基于二極管的正反向?qū)ㄌ匦裕谝欢妷悍秶鷥?nèi)能夠迅速響應(yīng)并消耗過(guò)高的電壓脈沖,從而降低電路中的電壓峰值,保護(hù)后續(xù)設(shè)備不被高壓電擊傷害。
瞬態(tài)電壓抑制器的主要特點(diǎn)如下:
1. 可以對(duì)各種電壓峰值和脈沖寬度的過(guò)電壓進(jìn)行抑制。
2. 可以快速響應(yīng),對(duì)瞬態(tài)過(guò)電壓進(jìn)行保護(hù),保證了電路的安全性和穩(wěn)定性。
3. 采用高靈敏度材料制作,具有低漏電流和低工作電壓的特點(diǎn)。
4. 長(zhǎng)期穩(wěn)定可靠,使用壽命長(zhǎng)。
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(tài)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(tài)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.
