Product Description

120W Permanent Magnet Synchronous Motor Driver Characteristics

■ Compatible with three-speed temperature controller direct input (HIGH, MED, LOW);

■ 9-speed, 3-group preset speed setting range from 400rpm~1200 rpm;

■ Maximum 120W power output;

■ IP54, CCC, CE (EMC, LVD) certified;

■ Metal shell, suitable for models: fan coil units #2-14;

■ Comprehensive energy saving rate: 50-80%;

■ Low inrush current ≤2A;

■ High-precision control, speed error ±5 RPM;

Description: The LD-H120-DS (HP) high-precision version has 3 external 0-9 digit encoder switches. By switching the encoder switches, 9 sets of speeds can be formed,

allowing one motor to adapt to fan coil units of the LDF 200-1400 model below 50PA.
