Main features D high-frequency DC switching power supply/DC converter
. The DC converter high-frequency switching power supply module adopts advanced dual-tube forward switching technology. The modules adopt an isolation design to prevent mutual influence between modules.
.In the case of + backup, even if one or several modules fail, it will not affect the parallel operation of other modules and automatic current sharing can be achieved between modules.
.High-frequency switching power supply module
Meet the power supply needs of grid system and grid system. The wide input voltage range is suitable for areas with large grid voltage fluctuations.
The meter-type module uses a half-digit meter to display the output current and voltage, which is simple and practical.
.The module is easy to install in a standard chassis with a width of inches and a height of 2 inches.
.Wide operating temperature range. Full power output can be achieved within the temperature range of -°C to +°C.
.High frequency switching power supply module
Small size and light weight.
