HYDROPOWER®
Patented electric power supply system.

Produce your electricy wherever you need it

The mini power-station HYDROPOWER, placed on a pipe of water supply network allows to furnish electronic devices used for the automatisation and centralised controls of isolated sites with 12 or 24 Vcc. Set up in a sight-hole or in a room of valves, HYDROPOWER is protected against vandalism and atmospheric disturbances. This equipment is delivered in DIY of three parts.
This is a simple and reliable solution,
it is easy to put into service.
A large range makes the machines suitable for most cases, for water flows between 6 and 120 m3/h.

Principle: The HYDROPOWER device is composed of a mini turbo alternator and an impervious battery which charge and discharge are controlled by an electronic unit of regulation and protection. The mini turbo alternator, moved by the water flow, loads the battery to supply a permanent electric power in spite of the intermittent cycle operating in the hydraulic networks. The different parts are dimensioned in accordance with the hydraulic conditions, and in order to supply the necessary electric power with a minimum pressure drop.

Applications: The HYDROPOWER device is able to supply with 12 or 24 Vcc every appliances of low permanent consummation such as: flowmeter, level transmitter, telecontrol remote units, etc... or on the contrary, electric device of more power but which daily average consummation is low, such as dosing pump, solenoid valve, motorised valve, etc...

Electronic control unit: It makes the tension of charge regular according to temperature, the current is self-regulated by the battery according to its rate of discharge. To avoid important discharges, the circuit of utilisation is cut by a static relay as soon as the battery tension falls to 11V (22V). It is automatically restored as soons as the tension goes up again to 12V (or 24V). A signal "battery alarm" points out that the tension went down to 11.8V (or 23.6V). A signal "end of charge" shows that the battery has recovered its normal charge. These two informations are generally transmitted by telecontrol. Their reading allows to control the running order of equipments. In some cases, they can be used to run the mini turbo alternator by remote control.

These two informations of telecontrol are delivered by photo-isolator free of tension. To avoid any risks of damage during the setting work, the electronic board is protected against inversions of polarity of the battery, and against the overload or short-cut by a quick electronic circuit breaker. The impervious battery doesn't need any upkeep. Its capacity is calculated in order to prevent, in normal working conditions, the rate of discharge doesn't exceed 20 to 25% the nominal capacity. This is to assume a maximal life and go a good work reserve.

Electric power: The alternators connected on the turbines have a power of 75, 100 or 200 VA. The daily avaible power is relevant to the working time. In order to avoid the lost of charge, the supplied power just fit the requirements, when establishing the plan of setting up.

The maximum pressure of use is 10 bars on PVC pipes and 16 bars on metallic pipes. For pressures superior to 16 bars, the mini turbo alternator can be delivered in a metallic socket.

Options: The control unit is usually fitted out with the complementary board HYDROTEST1 which permit posting up the running parameters of the device.The boards such as HYDROMAT, while piloting an solenoid valve or a motorised valve, make possible the working using local parameters such as the battery tension or the water level in the tank, the operating postponed by the clock and the operating by remote control from the master station. These boards allow to use the HYDROPOWER device on tanks through which a little volume pass daily, on water catchments which flows after change with the saisons, and on sites where consummation increases a lot during summer.Other kinds of boards make the conversion of tension 24/12V or 12/24V and operate like a static relay of power to manage a motorised valve.

The following board shows for each type of machine, the extreme flows it can accept counting with different kind of propellers, as well as dimensions (sheet above) and approximative weight.
