3A/4A(接线如3.3/1所示)或三相电源DCF 500B(接线如3.5/2所示)。
•电源
有几个组件需要电源:
-转换器的电源部分:200 V至1000 V,取决于转换器类型;见第2章
-转换器的电子电源:115V或230V,可通过跳线选择
-变频器冷却风扇:230V 1-ph;见技术数据
-电源部分现场电源:115 V至500 V;以及高达600 V的隔离/自动变压器;见第2章和/或
技术数据
-电机冷却风扇:取决于电机制造商/当地需求
-继电器逻辑:取决于本地需求
使用保险丝F1是因为C1和C2型转换器结构没有内置保险丝。所有组件,可通过115/230 V供电
将由一台隔离变压器T2供电。所有组件均设置为230 V电源或选择用于此电压水平。不同的
耗电元件是单独熔断的。只要T2有正确的分接头,它就可以连接到电源,用于给转换器的电源部件供电。
这同样适用于现场供电电路。有两种不同类型的匹配变压器可用。一个可用于电源电压
高500 V,另一个电压高690 V。不要将690 V一次分接与SDCS-FEX-1/2A现场电源一起使用!

- Typical configuration for high power drives connected in
12-pulse parallel Master-Follower application
(see chapter 3.6)
This configuration shows a 12-pulse parallel drive system. It is an
easy option to increase the power of a drive system. Depending on
the engineering features , redundancy or emergency operation, if
one converter fails, is made available.
Such drives use two identical 6-pulse converters and an especially
designed choke called T-reactor or 12-pulse choke or interface
reactor. The converters are fed by a 12-pulse line transformer with
separated secondary windings whose phase positions differ by
30°el.
An example is the transformer configuration Ì/ /Ì. This
configura SDCS-FEX-1 or 2A field supply. This field supply can be used at line voltages up to 500V and will give field current up to 6 / 16A. For higher field currents,
use the next bigger field supply unit DCF 503A/4A (wiring is shown at 3.3/1) or a 3-phase supply DCF 500B (wiring is shown at 3.5/2).
• Power supply
There are several components, which need a power supply:
- Converter´s power part: 200 V to 1000 V, depending on converter type; see chapter 2
- Converter´s electronics power supply: 115V or 230V, selectable by jumper
- Converter cooling fan: 230V 1-ph; see Technical Data
- Power part field supply: 115 V to 500 V; together with an isolating / auto transformer up to 600 V; see chapter 2 and / or

- Motor cooling fan: depending on motor manufacturer / local demands
- Relay logic: depending o
