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.

Electrical – Standard Installation

Background Information

There are a number of ways of establishing an electrical connection to operate your HOH Cell. In doing this a number of key factors must be considered.

  • The HOH Cell must only operate when the car is operating
  • It must stop when the vehicle stops.
  • A safety manual override is essential
  • Current limiting must be incorporated in case of current runaway

Objective of this information

To outline to the tools and minimum requirements for the electrical installation of your HOH Cell.


Tools and materials required
Crimping Tool
Screw Driver
Adjustable Wrench


Introduction

The information detailed here is the basic requirements to meet the criteria outlined in the Background Information, it should be easily installed my most mechanically mind people, though would cost little money to have an auto- electrician to do this for you.

High Performance Alternators

Third Party Product Review

Introduction:

The vehicles alternator provides the power source to operate the HOH Cell.

Many larger vehicles have heavy duty alternators that can operate at continuous amperage of 60 AMPs or more and in the trucking area this can be as high as 180AMPs, though 120AMPs is typical. In most vehicles the alternator produce 12-14VDC output which makes them ideal for the 6 Cell unit.

Once larger capacitites of gas is required the amperage needs to double in 15AMP increments for every litre of gas per minute. As this continues up to around 4 litres per minute (60AMPs) this tends to take most alternators to their limits.

Investigation in to high performance alternators has been carried out with the view of establishing an appropriate means to produce high output alternators that can provide the normal power to the vehicle’s systems, whilst at the same time produce up to 120VDC which is the legal limit in Australia for mobile power generation.

High voltage alternators and the associated devices connected need to be properly identified with shown warning label

Numerous alternators have been tested, with some standard alternator being modified to produce higher outputs:
