scope:

This specification covers the general requirements for tactical generator sets (hereinafter referred to as "set" or "sets") from 15 kilowatts (kW) thru 200 kW, 50/60 Hertz (Hz) and 400 Hz, alternating current (ac), skidmounted, diesel engine driven, liquid-cooled.

The sets shall be Type I (Tactical) and of the following Classes, Modes, and Sizes as specified on the applicable detail specification (see 3.1 and 6.2):

Class 1 - Precise. Class 2 - Utility. Mode I - 50/60 Hz. Mode II - 400 Hz (Class 1 only). Size 15 - 15 kW at 60 Hz (12.5 kW at 50 Hz). Size 30 - 30 kW at 60 Hz (25 kW at 50 Hz). Size 60 - 60 kW at 60 Hz (50 kW at 50 Hz). Size 100 - 100 kW at 60 Hz (83.3 kW at 50 Hz). Size 200 - 200 kW at 60 Hz (167 kW at 50 Hz).

Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: US Army Mobility Equipment Research and Development Command, ATTN: DRDME-DS, Fort Belvoir, VA 22060 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

The generator sets shall be rated 0.8 power factor (pf), lagging, and shall be reconnectable for the following voltage ratings:

(a) 3 phase, 4-wire, 240 volts line-to-neutral and 416 volts line-to-line (240/416 volts).

(b) 3 phase, 4 wire, 120 volts line-to-neutral and 208 volts line-to-line (120/208 volts).

intended Use:

The sets are intended to supply power for multipurpose use in military application. The general characteristics of the sets are described in MIL-STD-633 and MIL-STD-1332.
