Is there any installating surge arrestors to protect devices against switching surge, including AC supply variation or natural causes?

We have the arrestor protection circuit within the module and the maximum surge voltage is AC 275Vrms (according to IEC standard). Please note that the protection circuit is designed to protect the internal circuit of the module only.

有否安裝避雷器以保護設備不受開關浪湧,包括交流電源突變?

我們有避雷器保護電路模塊和最大浪湧電壓為交流275Vrms(根據IEC標準)。請注意,保護電路設計用來保護內部電路。

What type of dimmer is the CG400DM? Is it leading edge, trailing edge, or universal dimmer? Also, what is the minimum load handling capacity and maximum load capacity for resistive, inductive of electrical load?

The type of our CG400DM is a leading edge dimmer. The minimum load capacity for resistive load is 5W, inductive load is 400VA and capacitive load is 200VA. Please note that, the inductive load is referring to the wire wound transformer type for low voltage halogen lamp.

CG400DM是什麼類型的調光器?前緣,後緣或通用調光器?此外,最少及最大負載是多少?

CG400DM是前沿調光器。為阻性負載的最小負載能力為5W,感性負載是400VA和容性負載是200VA。請注意,在感性負載指的是金屬絲纏繞低壓鹵素燈變壓器的類型。

Can we use the CG400DM Dimmer as a motorised load for speed regulation? If so, what is the maximum load?

The CG400DM was designed for lighting control and the characteristic for inductive load is referring to the wire wound transformer. It is not recommended to use the CG400DM for motor control applications.

我們可以使用調光器CG400DM作為調馬達負荷?如果是這樣,什麼是最大負荷?

該CG400DM設計用於照明控制,不建議用於電機控制應用的。

In a three-phase installation situation, if the "Neutral" line becomes loose and goes missing resulting in a voltage of approximately 440V AC, then in this circumstance, then can the device withinstand this high voltage for a long period of time? What kind of protection should we use to prevent this type of fault from occuring?

Under such circumstance, when a low impedance device (high power devices) on one of the three phases is turned ON, a very high voltage will apply to the high impedance devices (chargers, our light switches in OFF state or No loading) on the other two phases because it is an unbalance system. All the high impedance devices (not only our light switches) will be damaged. To avoid this situation, the only way is to ensure the robustness of the Neutral wiring.

在三相安裝的情況下,如果“中缐”變鬆,缺失導致約440V交流電壓,那麼在這種情況下,設備可承受長時間這個高壓?我們應該用什麼樣的保護,防止此類故障的出現?

唯一的方法是確保該中線佈線的穩健性。

Zigbee works on the IEEE802.15.4 standard,therefore if other manufacturers have products that use the same standard, then can we use these products with CityGrow?

The IEEE802.15.4 standard is a MAC layer standard for peer-to-peer communication。The comaptibility of different products from different manufacturers depends on the design of not only the MAC layer standard, but also both communication protocol stack and application layer. Therefore we must know which product that you desire to integrate with our system before we can answer the question.

Zigbee的工作於IEEE802.15.4標準,因此,如果其他廠商有使用同一標準的產品,那麼我們就可否使用這些產品與CityGrow一起工作嗎?

不可以。
