5V DCAC SMPS 12V Power Supply for CT Switch Mode Power Supply Transformer

The switch mode power supply (SMPS) of the self-powered current transformer has a strong adaptability to transmission line current variations, and can achieve stable power output within the range of normal cable current variations.

 



Introduction:

D.C. to D.C. converters and D.C. to A.C. Converters belong to the category of Switched Mode Power Supplies (SMPS). The various types of voltage regulators, used in Linear Power Supplies (LPS), fall in the category of dissipative regulator, as they have a voltage control element usually transistor or zener diode which dissipates power equal to the voltage difference between an unregulated input voltage and a fixed supply voltage multiplied by the current flowing through it. The switching regulator acts as a continuously variable power converter and hence its efficiency is negligibly affected by the voltage difference. Hence the switching regulator is also known as ‘non-dissipative regulator’.

Features:

1. Start to take electricity from a small load current and maintain a regulated output.

2. CT with open circuit and high current impact protection, and maintain a regulated output.

3. Open type current transformer structure, easy to install and unload.

4. Insulating shell, epoxy potting, explosion-proof and flame-retardant, safe to use.

5. Replace high-pressure PT, economical and practical.

 

Application:

  • Suitable for motor protection ,relay protection,small current grounding system
  • Suitable for electrical fire monitoring systems
  • Flexible output method
  • Through structure ,epoxy resin casting,good stability
  • High permeability permalloy or nanocrystalline ,with good linearity and high sensitivity
  • Excellent balance characteristics and extremely strong immunity to electromagnetic fields.split-core current transformers. The CT can be mounted to existing panels, such as control centers or load centers, to measure or monitor wattage. These CTs can be mounted without removing existing cables for easier installation.
