This CID is meant as a minimum requirement for the pulse generator in which only those manufacturers that meet or surpass the following requirements are qualified per this CID. 2. CLASSIFICATION Equipment covered by this CID may be commercially available equip
3、ment modified to the extent necessary to meet the following description. The equipment shall be Type III, Class 5, Style E and Color R in accordance with MIL-T-28800. 3. SALIENT CHARACTERISTICS 3.1 Design and construction. The equipment shall be UL (Underwriters Laboratories) listed and approved and
4、or shall comply with the Type III safety requirements of MIL-T-28800. 3.2 Electrical power sources . The equipment shall operate from nominal commercial, military and shipboard power sources of 115/230 volts AC (*lo%) at line frequencies of 50 to 60 Hz. Transient state conditions shall meet MIL-T-28
5、800 Class 5 requirements.
