APPLICATION AREAS:
1. Railways and trams: For the protection of electrical equipment, power electronics (IGBT, thyristors...) in systems with alternating, direct or combined AC + DC power supply, especially in power supply of AC/DC, DC/AC, DC/DC converters. They may be used in systems with main and auxiliary power supply for example: automatic control and regulation systems, cooling systems, warming systems, ventilation systems, and combination systems (electromechanical, electropneumatic and other systems).
2. Wind powerplants For protection of automatic control and regulation in power electronics (IGTB, tyristors...), as well as the protection of sensitive electronic systems (e. g. AC/DC, DC/AC, DC/DC converters, drive systems) from direct or indirect lightning strikes.
3. Photovoltaic systems For protection of photopanels, automatic control electronics with sensitive electronic components, and DC/AC converters (inverters) from direct or indirect lightning strikes. Depending on the application, both serial and parallel connections are possible. With serial connection the required voltage is achieved. With parallel connection higher current absorption is achieved in the modules.

Safely Monitor Current with a 200/5
Safety should always be of paramount importance when designing and installing electrical systems. An appropriate current transformer, such as one rated at 200/5, may be an essential purchase when you need to easily transform a current from a very high voltage to a lower one as needed. In some cases, current transformers may connect with monitoring sensors to provide a safer operational posture and a clear idea of how a given electrical system performs. At Fastron, we've simplified the often complex buying process for items such as these, and we've created an online storefront that keeps you from rummaging through endless numbers of bins at the local electronics shop. Consider what you can accomplish with this product and the features of the 200/5 transformers we supply.
Fast Facts About Our 200/5 Options
With so many options on the market, it is important to know you're about to purchase the right product for the task you have in mind. What should you know about this particular current transformer? A few quick facts to consider:
Each unit is relatively low cost considering its function, yet built to meet exacting standards. Each unit features a design allowing it to support a primary current of 200 amps with a secondary current of 5 amps.
Be mindful of each component's minimum and maximum operational temperatures. According to the manufacturer datasheet, the 200/5 current transformer has a minimum rated temperature of -30C and a maximum of 85C.
Our units are compatible with standard DIN rail technology and include a mounting clip to make the installation process quick and simple. Quickly and accurately feed current information to an ammeter with this unit.
