DC/DC converters offer efficient drop in harsh environments

Murata has revealed its latest addition of the OKI-78SR-E series of three terminal non-isolated DC/DC converters designed by Murata Power Solutions for use in harsh environment applications. The series features three modules with a fixed single output voltage of 3.3V at 1.5A, 5V at 1.5A and 12V at 1A. The converters provide a cost effective, highly efficient alternative to a T0-220/78xx series linear regulator.

The fully encapsulated module is rated to operate from -40 to 85°C and can be used in almost any application where a single output of 3.3, 5 or 12V is required. The 3.3 and 5V models operate from an input range of 7-36V and the 12V model in the range of 15-36V. All models are available in either vertical or horizontal SIP mounting options using a linear regulator compatible pin out. The efficiency of the 12V OKI-78SR-12/1.0-W36E-C device when powered from a 24V source is more than 95% eliminating the need for a heat sink, reducing cost and complexity during the manufacturing process. Additional features include short circuit and over current protection.

The OKI-78SR-E series incorporates advanced assembly techniques, to produce a technology-leading board mounted power module. It is suitable for applications ranging from high reliability networking and telecommunications, to railway applications and communications, and to control systems, lighting and computing systems. The modules are very effective for applications including those intended for industrial environments with limited airflow for cooling, limited space, or the desire to improve the overall system efficiency by eliminating the linear regulator.

Incorporating the latest PWM technologies for power conversion, customers purchasing the OKI-78SR-E series can be assured that its efficiency, high reliability and optional packaging configurations all offer an unmatched level of performance. Standard features include UL safety approvals, as well as state of the art performance for thermal management, dynamic load response, industry standard package and OCP protection features.
