Frequently Asked Questions

The H20 Drive RD300 is a variable frequency drive (VFD) constant pressure controller designed to control submersible well pumps and maintain steady water pressure in residential, commercial, or irrigation systems. It automatically adjusts pump speed based on water demand.

What pump size is compatible with the RD300?

The controller is designed to operate 3-phase submersible pumps from 2 HP to 3 HP, making it suitable for larger residential and light commercial water systems.

What voltage does the H20 Drive RD300 operate on?

The RD300 uses 200–240V single-phase input power and converts it to 208/230V three-phase output to drive a three-phase pump motor.

How does the RD300 maintain constant water pressure?

The system uses a pressure transducer to monitor system pressure and a VFD to automatically increase or decrease pump speed to maintain the desired pressure setting.

Does the controller include a pressure sensor?

Yes. The RD300 includes a 0–150 PSI pressure transducer with cable that continuously measures system pressure and sends data to the controller.

What information does the display show?

The controller includes a bright color LCD display that shows important system data such as system pressure (PSI), pump speed (Hz), pump amperage, pump run status, and alarm messages with history, allowing users to easily monitor pump performance.

What protection features are included?

The RD300 includes several built-in protection functions such as pump dry run protection, high and low pressure alarms, motor overload protection, transducer fault monitoring, and a well recharge timer, which help protect the pump and improve system reliability.

Is the RD300 suitable for outdoor installation?

Yes. The controller comes in a NEMA 3R weather-resistant thermoplastic enclosure, which allows installation in indoor or outdoor environments.
