P-Duke has announced the launch of its new MCF series which consists of front-end filters for P-Duke COTS (commercial-off-the-shelf) DC/DC Converters. These filters comply with the requirements of MIL-STD 1275D (characteristic of 28-volt DC electrical systems in military vehicles) and MIL-STD 461 (requirement for the control of electromagnetic interference characteristics of subsystems and equipment).

The filters are best suited for heavy industrial, military and rolling stock applications, as this series accepts 9-36Vdc input voltage (50Vdc for 1 sec). The MCF series also offers active input over-voltage protection which clamps over-voltages for maximum 50ms up to 100V to a safe level of 40V and absorbs +/-250V spikes with the internal protection circuits. It also features other active protection functions for an advanced protection of the DC/DC converter module such as remote on/off control, overload protection, output short-circuit protection, reverse polarity protection, inrush current limitation.

Together with P-Duke COTS DC/DC converters, a significant cost saving is offered as compared to using traditionally developed military DC/DC converters in the power range of up to 250W. The MCF filters meet the environmental MIL-STD 810F specification for shock and vibration. The operating temperature range of -40°C to 105°C (optionally -55°C) allows to use these MCF filters with P-Duke DC/DC converters in a wide range of demanding applications.
