DC-DC Converter

BHV20170526_B01

The NHV series is our mid-to-high voltage DC-DC converter featuring high accuracy and low noise. Its design for

minimizing line regulation, load regulation, temperature drift and time-course drift enables highly accurate and stable

voltage to be provided. A hexahedron metal shield case ensures low noise along with a selection of a circuit suitable for

noise suppression. Output voltage is adjustable by external voltage or an external variable resistor. A built-in short-circuit

and over current protection ensure high reliability and a long life.
