1. Introduction to HR AC/DC submersible pumps

HR AC/DC is a 4” submersible pump for clean water applications:

• Three phase permanent magnet motor with wet rotor and canned type resin filled stator.

• Built-in inverter on board.

• Helical rotor pump.

Pump inverter allows the following:

• Modified pump speeds that allow the pump to run at its highest efficiency point based on

the power available.

• Soft start and soft stop to increase the system life and reduce the current peaks.

• Protects the motor from overload, dry running, overvoltage, under voltage and possible

abnormal conditions.

HR AC/DC pumps can be used in residential and industrial applications with pressurized water

systems that create:

• Energy savings.

• Simple and quick installations.

• Long life and reliability.

HR AC/DC pumps can be fed both AC and DC power with a wide range of operating voltages (90-

265 VAC or 90-400 VDC).

This means that the same pump can be powered by photovoltaic panels, wind, generator or

batteries. The hydraulic performance will be adjusted automatically according to the power source

and the power available.

With photovoltaic panels, an MPPT algorithm is used to maximize the pump’s output based on

available sunlight.

Pump speeds are adjusted in relation to solar irradiation. When solar irradiation increases, the

pump will run faster and pump more water. When solar irradiation decreases (clouds moving

and/or different hours of the day,) the pump will reduce its frequency and slow down, but it will

continue pumping until the solar irradiation reaches the minimum value necessary to keep

pumping.

HR AC/DC pumps can be installed with or without the Control Module controller (CM MP). The

controller records the following:

• Run time.

• Input voltage, current and power.

• Alarms: dry running, overload, overvoltage.

Digital inputs make it possible to connect a float switch, a pressure switch, start and stop signal,

etc...

Running and alarm status are given by two digital outputs.

Analog inputs can be used to connect sensors (i.e. flow meter).
