Encapsulated DC/DC Converter for Heavy Duty Applications
Absopulse Electronics’ PDC 250 line of DC/DC converters are designed for operation in harsh environments. Full encapsulation in a thermally conductive MIL-spec. silicon rubber compound ensures immunity to shock, vibration, humidity, moisture, salt and airborne contaminants. The unit performs to full specification at temperatures from -40°C to 70°C with installation on an appropriate size heat-sinking plate. Housed in a 4.2" × 2.75" × 7.5" enclosure the converter delivers a single output of 12V DC/20A, 24V DC/10A, 36V DC/17A, 48V DC/5A or 72V DC/3.3A. Input ranges include 125V DC (105-140V) or 250V DC (210-280V), and the unit is capable of continuous operation within these ranges. The device is filtered to meet EN 55022 Class A EMI with wide margins and is designed to meet EN 60950 and related standards. The unit features inrush current limiting and surge protection on the input. Output protection includes current limiting with short-circuit protection and thermal shutdown with self-resetting. Pricing starts at $371 in quantities of 100.
