The PS1200 series controller operates the ECDRIVE-1200 motor for up to 1200W of pumping power. Having seven models of HR-series and three models of C-series submersible pump ends to choose from, for performance up to 800ft TDH or up to 89 GPM, this series fits a wide range of applications. The HR series pump end is a progressive-cavity type pump. It uses a helical rotor to push small pockets of water through the pump end at high speed. Various models to choose from allow optimization for the head pressure or flow rate required.PUMP The Lorentz PS-HR range are high specifications solar powered helical rotor pumps specifically designed for high head borehole applications and feature a remote surface mounted controller. Pumps are constructed principally from AISI 304/316 stainless steel and are engineered to the highest standards to give easy serviceability, excellent efficiency, high reliability and long life. MOTOR The pumps are fitted to ECDRIVE HR maintenance-free, water-filled brushless DC motors without integrated electronics. They should be powered by solar arrays configured to provide the input voltage required and sized at approx 120% of the rated motor power. Speed: 900-3300 rpm Insulation Class: F Enclosure Class: IP68 CONTROLLER Pumps are provided with matched controllers for monitoring, protecting and controlling pump operation that feature:- Protection against reverse polarity, overload and over temperature. Integrated MPPT (Maximum Power Point Tracking) for maximum solar energy conversion efficiency. Low voltage disconnect for battery protection. Control inputs for dry running protection and remote control. PUMP OUTPUTS Pump output curves are given at standard test conditions of 1000W/m2 solar irradiance and 250C. Output will vary throughout the year depending upon prevailing irradiation levels. For estimated daily outputs at continuous pumping multiply the indicated output at the duty point by the daily irradiation given in Graph 1. For indicative purposes factors of 1.1 can be applied for hot arid areas and 0.9 for temperate high altitude areas in East Africa. Output will vary throughout the day as a proportion of the estimated hourly irradiation as shown in Graph 2. NOTE: Output estimations are strictly indicative. More accurate projections are available using manufacturers data when the exact site location and installation arrangement is defined. This information will be provided with all offers.
