Datasheet

Powergood has added two new 4:1 input models to their high efficiency ESM Series. The ESM brick (1.87”x 1.16” footprint) parts are capable of delivering up to 35W of output power, or up to 10A of output current at lower output voltage. The low-cost devices are designed to operate efficiently over a 4:1(2:1) input range of 18 to 75 VDC, facilitating their employment on boards with industry standard bus voltages of 24V, 48V or 60V. Notably, their ultra-wide input range permits the use of single power system designs, which are capable of operating in an extensive array of environments. The Series is RoHS compliant and withstand a basic isolation voltage from input to output of 2250VDC. Now, ESM modules have pinned version option, are aimed at customers who do not require surface-mount modules and prefer conventional, through-hole assembly methods.

The open frame construction of the ESM Series, combined with its input voltage range and footprint of less than 1.2-square inches, makes it highly appropriate for use in a wide assortment of networking, telecom, wireless and industrial designs requiring tight board spacing. The most common employment is on PC boards in mobile/optical switches, high capacity network routers, high-end datacom and medical systems, as well as in a variety of systems using distributed power architecture.

ESM converters boast fixed frequency synchronous rectification control for high efficiency, together with positive/negative remote sense, remote on/off logic, and +/-5% output trim. Protection features include input and output over-voltage protection, over-temperature protection, current limit and short circuit protection, and under voltage lockout. They are provided with either active-high or active-low on/off polarity. Modules operate over an ambient temperature range of -40 to +85 degrees C.
