Transient Protection DC DC Converter

Transient  Protection DC DC Converter (also called Transient Suppression DC DC Converter or Surge Protection DC DC Converter) were developed for many years. Transient Protection DC DC Converter have been serialized, standardized and market-oriented. Transient Protection DC DC Converter use forward pulse width modulated topology design. The operating principle is that the sampling signal of output voltage, coupled by the opto-coupler, works together with the sampling signal of input loop current to regulate the pulse width of the controller. The double close loop control can create constant voltage output and short circuit protection. The magnetic feedback technology can effectively prevent the magnetic saturation of transformer and also products reliability can be improved.

Transient Protection DC DC Converter featured with the lowest output voltage is 3.3V. The maximum output power of  the transient suppression DC DC Converter can reach 1400 watts, with single,double,three ways and multi-ways output varieties.
