The Mosa GE 20 YSX Multi Voltage is a Diesel Generator powered by a reliable and quality YANMAR 4TNV88 engine.  A three-phase synchronous, brushless alternator provides three phase and both 230V and 110V single phase power generation. Providing 20 kVA three phase and 7 kVA single phase power through 1 x 400V, 1 X 230V (32A), 2 X 115V (32A) and 1 X 115V (16A) sockets.

The Mosa GE 20 YSX is a super silenced diesel generating set. The machine construction incorporates an integral roll bar, central lifting point, forklift pockets and rear canopy section that is hinged to provide full access to the engine for maintenance. A 100 litre fuel tank provides a running time of 29.5 hours. At 750kg the machine is compact and easily transportable using the optional site, road tow trailer or a special galvanized skid base frame, available below.

Attention to detail can be seen in the rounded edges of the canopy designed for rainwater drainage away from the control panel.

A bunded base ensures containment of fluids in the engine and fuel tank in the event of any loss, to prevent their dispersion in the environment.

When the Compound System is combined with a double control AVR the Compound System overrides the AVR when a heavy load is applied and also provides a backup voltage regulation in the event of AVR failure.

EAS models are pre-wired to accept the optional MOSA EAS Automatic Start-Up Panel which plugs into the front panel of the Generator and enables the machine to be used as an emergency standby power unit in the event of power failure from the mains supply.

Also available is an optional TCM remote control allowing start/stop of the engine up to 10 metres distance from the machine.

Suitable for a wide range of uses including industrial sites, residential, construction, noise sensitive environments and emergency standby power.

In according with CE regulation


EXTRAS ON REQUEST: Mosa TCL20 Site Trailer and 2 options of Road Trailers, Earthing Kit, Remote Control TCM35, Automatic Transfer Unit and Galvanized Skid base frame


Having both functions gives double assurance of the power supply: With this system both AVR and Compound control systems are normally active. When a heavy load current is required (example – motor starting) the compound regulation overrides the AVR thereby ensuring high availability of required current. In standard operating conditions the AVR regulation prevails, which ensures high quality, precise control of the AC output.

In case of AVR failure, the Compound regulation maintains voltage regulation, albeit with reduced control characteristics.

These systems make the generator perfect for running machines (like a compressor for example) or sensitive equipment (like laptops etc)
