General Information – (Specifications provided by uni-power on request)

These alternators can be provided in dual wound configuration, providing both the standard 12VDC supply and an isolated 120VDC output on the secondary.

The Uni-Power 3500 is designed to satisfy an increasing requirement for reliable and economical
240/110 volt mobile power on motor vehicles.

The system which comprises of a Uni-Power alternator and a control module is capable of supplying
an output of 3500 watts (3.5kVA) peak power or a continuous rating of 3000 watts (3 kVA).

The Uni-Power 3500 was originally designed for the purpose of providing heating in mobile food
vans and to cater for high energy power tools such as jackhammers, pipe threading equipment, etc.
Fire Engine manufacturers now regularly purchase these to provide 240V power for “Stemlite”
Lighting towers in a compact form.

The current model provides chopped D.C. power which is fully regulated to 120V (+/-10%).
Chopped D.C. behaves much like A.C. current as far as mechanical switches are concerned and will
not produce arcing problems inherent with normal D.C.
