  
Franklin Monodrive variable speed constant pressure controllers are designed to provide constant pressure for 230 volts, single-phase, three-wire submersible water well pump systems.
Specifications
- Application: You can have constant pressure just by replacing the three-wire control box in a conventional system. Ideal for applications where constant pressure is desirable: residential water systems, landscaping, water treatment and geothermal applications.
- Operation: The MonoDrive ( 1/2 Hp, 3/4 HP or 1 HP) converts a conventional pump system to a variable speed constant pressure system by simply replacing the 3-wire control box and pressure switch. Maximum pump output using the MonoDrive is similar to the performance achieved using a conventional control box. Therefore, the pump selection criteria are the same as if a control box were used.
- Input (From Power Source): Voltage: 190-260 Volts 1 Phase; Frequency: 60/50 Hz;
Power Factor: 1 (Constant).
- Output (To Motor):
Voltage: Variable / 1-Phase/3-wire;
Frequency: Variable 30-60 Hz; Max Amps (RMS): 1/2 HP 4.0 A; 3/4 HP 6.6 A; 1 HP 9.0 A.
