Frequently Asked Questions:

What is the H20 Drive RD500 used for?

The RD500 is a variable frequency drive (VFD) constant pressure controller designed to control submersible well pumps and maintain stable water pressure in residential, agricultural, or commercial water systems. It automatically adjusts pump speed based on water demand.

What pump size is compatible with the RD500?

The RD500 is designed to operate 3-phase submersible well pumps up to 5 HP. It supports pumps with service factor amps around 17.5–17.8 amps, depending on the motor specifications.

What voltage does the RD500 operate on?

The controller typically accepts 200–240V single-phase input power and converts it to 208/230V three-phase output to run a three-phase pump motor.

How does the RD500 maintain constant pressure?

The system uses a pressure transducer to monitor water pressure and a VFD to automatically adjust the pump speed. When water demand increases, the drive increases motor speed; when demand decreases, it slows the pump to maintain consistent pressure.

Does the RD500 include a pressure sensor?

Yes. The controller includes a 0–150 PSI pressure transducer with cable that continuously measures system pressure and sends feedback to the controller for accurate pressure regulation.

What information does the display show?

The controller includes a bright color LCD display that provides real-time system information such as system pressure (PSI), pump speed (Hz), pump amperage, pump running status, and alarm messages with system alerts, helping monitor pump performance easily.

What protection features are included in the RD500?

The RD500 includes several built-in protection features such as pump dry-run protection, high and low pressure alarms, pump motor overload protection, transducer fault monitoring, and a well recharge timer, helping extend pump life and protect the system.

Is the RD500 suitable for outdoor installation?

Yes. The controller is housed in a NEMA 3R weather-resistant enclosure, allowing installation indoors or outdoors.
