Bedford Sinlge Phase B501DSL Solar Photovoltaic Pump Controller

Bedford Sinlge Phase B501DSL Solar Photovoltaic Pump Controller. Advanced MPPT Technology: Maximizes solar cell array efficiency by automatically adjusting motor speed and water flow based on sunlight intensity. Dual Power Input: Compatible with both Solar DC (220-370V) and AC Power (1 Phase 220V) for flexible hybrid power input. Automatic Water Level Control: Automatically sleeps at high water levels and restarts at low levels, preventing anhydrous idling and saving energy. Battery-Free Operation: Replaces batteries in solar pump systems, retaining water without any battery components for cost-effective operation. Comprehensive Protection: Features multiple protection functions to prevent pump damage and improve the reliability of the whole system. Versatile Motor Compatibility: Suitable for single-phase pumps with or without starting capacitors, and three-phase motors via specific settings. Wide Application Scope: Ideal for farmland irrigation, orchard watering, deep well pumping, and water tower feeding applications. High Reliability Design: Utilizes Fuji/Infenion IGBTs and high carrier frequency PWM control for stable performance and self-protection.
