2、. SCOPE 1.1 e, This specification covers general requirements for single phase, 400 Hertz (Hz) lternating current (a.c.) line voltage regulators intended for shipboard application. The single-phase regulators shall operate in a three-phase bank when connected in a our- wire wye circuit with or witho

3、ut a grounded neutral, or in a delta circuit. 1.2 Classification. The. continuous load capacity of the three-phase bank shall be limited by the maximum lhe current rating of the single-phase equipment. be of the following ratings as specified (see 6.): # Equipments shall 115 volt system - Equipments

4、 are rated at 115 volts (V) root-mean-square (RMS) and the follming maximum continuous output line currents: 75 amperes RMS 150 amperes RMS 225 amperes RMS 440 volt system - Equipments are rated at 440V RMS and the following maximum con- tinuous output line currents: 20 amperes RMS 40 amperes RMC #
