Technical Profile

Introduction

SK711 is a wide input board type converter supporting input range from 18V to 36V. Possessing military standard filter for EMI avoidance, SK711 guarantees the stability of voltage and electric current for system operation, especially suitable for application in military or other harsh environment. Furthermore, with parallel design, two SK711 can be combined for double power of 300W, supporting prominent system performance. Compliant with MIL-STD 1275/461,  extended operating temperature from -40 to 85°C, SK711 performs as an ideal converter module for severe environmental usage. The Cosel Hi-Rel DC/DC CONVERTER it also provides , Output Over Current Protection (OCP), Output Overvoltage Protection (OVP) and Over Temperature Protection (OTP) to made stability and safty.
