Mecc Alte SpA is one of the world's largest generator manufacturers, with an annual turnover exceeding 75 million euros. Headquartered in Italy, with manufacturing facilities in the UK and warehouse and worldwide sales support facilities in the US, France, Germany, Poland, Spain, Singapore, and Australia, Mecc Alte offers a wide range of generation products, from small 1 kW to 14 kW 3000 rpm and 3600 rpm 2-pole generators for portable applications, to very large2400 kW 4-pole generators for stationary applications.

Data files, parts lists, drawings, and manuals on some common Mecc Alte generators, including the older AP, AR1, AR2, MR1, MR2 and the newer S15W, S15F, S16W, S20F, and S20W models can be directly accessed from the index on our Mecc Alte Data Index page. If you need further data on a Mecc Alte model not available from our index page, then the data can most likelybe obtained from the download area of Mecc Alte's main web site; which can be accessed from our web link to theMecc Alte download area.

TRACTOR PTO GENERATORS

In addition to using Mecc Alte generator ends on some of the generator sets that we fabricate, we also offer a wide range of Mecc Alte tractor style PTO generators, as can be seen in the selection of units in the photo shown here. Each model is fitted with a gear reduction box. Not shown in the picture below is a conical safety guard for the drive connection that is supplied with each PTO assembly

SIZING: In sizing a tractor PTO generator, it is important to make sure that 540 rpm tractor PTO's are matched with 540 rpm PTO generators and that 1000 rpm tractor PTO's are matched with 1000 rpm generators. In addition, a common rule of thumb is to insure the availability (at the tractor PTO) of about 1.7 HP for every kW of desired electrical power, although in some cases a bit less may be required.

Notes: The power ratings noted here are for continuous duty, single phase 120/240 VAC, 1.0 pF. For standby duty these can be increased by 10% for 1 hour in every 6 hour period. All models shown here require a 1 3/8" - 6 spline input shaft, commonly available at tractor dealers (or from us, if required). All 1800 rpm AVR regulated alternators are 12 lead reconnectable machines, and can be connected for three phase operation with somewhat greater power output capacity (~20%). The 3P2 gear reduction case is aluminum; the M5, M7, M9 & M10 gear cases are cast iron. Data sheets for the actual Mecc Alte generator end used are either linked here in the table above, or available upon request. The S20W and S20FS and S20F models replace older similar MR1 and MR2 models. For example, the new style S20F-200/A can be used as an exact physical replacement for the older MR2-200/2, and it will have an improved electrical rating.

Optional Outlet Box – Good up to 10 kW
