The HHF28 Series of military grade DC-DC converter offer up to 15 watts of output power with high reliability. The HHF28 series’ small size, light weight, and hermetically sealed metal packages make them ideal for use in aviation aerospace and other high reliability applications.

The HVHF28 series products are designed using forward PWM principle and are new generation 20W series high-reliability military grade DC/DC converter developed through improvement. After being isolated and coupled through optocoupler isolation, the sampling signal of output voltage of the product and the sampling signal of current in input circuit modulate the pulse width of controller at the same time

The HHD28 Series of military grade DC-DC converters offer up to 20 watts of output power with high reliability. The HHD28 series’ small size, light weight, and hermetically sealed metal packages make them ideal for use in aviation aerospace and other high reliability applications.

The HTR28 Series of defense military grade DC-DC converter offer up to 30 watts of output power with high reliability. The converters are packaged in hermetically sealed metal cases, making them ideal for use in aviation, aerospace and other high reliability applications.

The HFL28 Series of military grade DC-DC converters offer up to 65 watts of output power with high reliability. The converters are packaged in hermetically sealed metal cases, making them ideal for use in aviation, aerospace and other high reliability applications.

This series products are high reliable hybrid thick film large power military grade DC/DC converter. By using half-bridge circuit topology and pulse width modulation principle, the output sampling voltage isolated by opto coupler to modulate the pulse width and form the closed-loop control to make the product a stable voltage output.
