CUI has added a line of rugged DC/DC converters which feature a very wide input voltage range, and which provide between 50W and 200W of output power.
The wide input range of the VHK series converters makes them ideal for applications using a power source with a fluctuating output such as a battery, which exhibits large voltage swings across the charge/discharge cycle.
The converters are housed in a rugged chassis-mount enclosure. This aluminium case measures 108 x 102 x 38mm, and includes a built-in heat sink which provides for excellent thermal performance.
Users can select one of two input voltage ranges: 9V to 36VDC or 18V to 72VDC. The available output voltages are 3.3V, 5V, 12V, 15V, 24V, 28V and 48V.
The standard operating temperature range of the VHK series is -40°C to +85°C; the 50W model operates at up to +60°C with convection cooling.
Other notable features of the new family of converters include high efficiency, a fast response to voltage transients, remote sense capability and remote on/off control.
