Delta Frequency converters VFD-CP2000 series Price List

Delta VFD185CP43B-21 is a fan and pump dedicated inverter from the CP2000 series, optimized for energy-saving operation in various fluid systems with three-phase 380–460V input and 18.5kW rated output power. It features an energy-saving control mode that adjusts motor speed according to actual system demand (pressure/flow/temperature), significantly reducing power consumption compared to traditional throttle control methods. The inverter integrates a PID controller with auto-tuning function, enabling automatic regulation of system parameters to maintain stable operation, and supports advanced functions such as sleep/wake control (to save energy during low-demand periods), pump rotation control (to prevent pump jamming), and dry-running protection (to avoid pump damage). It provides a wide output frequency range (0.1–600Hz), soft start/stop function (0.1–300s acceleration/deceleration time), and multiple control modes (local, remote, communication). Comprehensive protection functions include overcurrent, overvoltage, undervoltage, overload (120% for 60s), overheating, phase loss, short circuit, and motor thermal protection. With its user-friendly design (detachable control panel, real-time parameter display), high efficiency (>95%), and reliable performance, this inverter is widely applied in water supply, drainage, HVAC, and ventilation systems to improve energy efficiency and reduce operational costs.
