The modules achieve full load efficiency of 88% at 3.3V output voltage. The open frame modules construction, available in both surface-mount and through-hole packaging, enable designers to develop cost- and space-efficient solutions. Standard features include remote On/Off, remote sense, output voltage adjustment, overvoltage, overcurrent and overtemperature protection. * UL is a registered trademark of Underwriters Laboratories, Inc. † CSA is a registered trademark of Canadian Standards Association. ‡ VDE is a trademark of Verband Deutscher Elektrotechniker e.V. ** ISO is a registered trademark of the International Organization of Standards October 1, 2015 ©2012 General Electric Company.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 6A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information. October 1, 2015 ©2012 General Electric Company. All rights reserved.

Feature Description (Continued) The output power of the module should not exceed the rated power for the module (Vo, set x Io, max). Tref Overcurrent Protection To provide protection in a fault (output overload) condi¬tion, the module is equipped with internal current- limiting circuitry, and can endure current limiting continuously. At the instance of current-limit inception, the output current begins to tail-out. When an overcurrent condition exists beyond a few seconds, the module enters a “hiccup” mode of opera¬tion, whereby it shuts down and automatically attempts to restart upon cooling. While the fault condition exists, the module will remain in this hiccup mode, and can remain in this mode until the fault is cleared. The unit operates normally Air Flow once the output current is reduced back into its specified range. Figure 43. Tref Temperature Measurement Output Over Voltage Protection Location. The output overvoltage protection clamp consists of control circuitry, independent of the primary regulation loop, that monitors the voltage on the output terminals. Please refer to the Application Note “Thermal This control loop has a higher voltage set point than the Characterization Process For Open-Frame Board- primary loop (See the overvoltage clamp values in the Mounted Power Modules” for a detailed discussion of Feature Specifications Table). In a fault condition, the thermal aspects including maximum device overvoltage clamp ensures that the output voltage does temperatures. not exceed Vo,ovsd, max.

Overtemperature Protection To provide protection under certain fault conditions, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the thermal reference point Tref o (Figure 43), exceeds 125 C (typical), but the thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module will automatically restarts after it cools down. Thermal Considerations The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel.
