High- density front-to-back airflow is designed for minimal space utilization and is highly expandable for future growth. The wide-input 2 standard product is designed to be deployed internationally. It is configured with both RS485 and dual-redundant I C communications busses that allow it to be used in a broad range of applications. These signals and the 5V auxiliary supply are isolated from the main output and frame ground. Feature set flexibility makes this rectifier an excellent choice for applications requiring modular AC to - 48VDC intermediate voltages, such as in distributed power. * 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. § This product is intended for integration into end-user equipment.

If to exceed the 32 byte page limitation of the device. communications are not stopped during this interval, multiple power supplies may respond to specific instructions because the address of the hot plugged power supply always defaults to xxxx000 (depending on which device is being addressed within the power supply) until the power supply configures its address. The recommended procedure for hot plug is the following: The system controller should be told which power supply is to be removed. The controller turns the service LED ON, thus informing the installer that the identified power supply can be removed from the system. The system controller should then poll the module_present signal to verify when the power supply is re-inserted. It should time out for 15 seconds after this signal is verified. At the end of the time out all communications can resume. Predictive Failures Alarm warnings that do not cause a shutdown are indicators of potential future failures of the power supply. For example, if a thermal sensor failed, a warning is issued but an immediate shutdown of the power supply is not warranted. Another example of potential predictive failure mechanisms can be derived from information such as fan speed when multiple fans are used in the same power supply. If the speed of the fans varies by more than 20% from each other, this is an indication of an impending fan wear out. The goal is to identify problems early before a protective shutdown would occur that would take the power supply out of service. Specifications are subject to change without notice.
