specification model mtbf dimension note packing 1. all parameters not specially mentioned are measured at rated load and 25 of ambient temperature. 2. every 25 seconds, unit will send out test signal through "battery fail" re lay contact and led indicator once the battery is fail. 3. the power supply is considered a component which will be installed into a fi nal equipment. the final equipment must be re-confirmed that it still mee ts emc directives. for guidance on how to perform these emc tests, please refer to ?emi testing of c omponent power supplies.?
