About VSRE48-003 - Crompton VFD - 0.75 kW / 1HP 3-Phase 380V Solar
The Crompton Greaves Emotron VSRE48-003 is a high-efficiency 0.75 kW (1 HP)
Solar Variable Frequency Drive (VFD) configured for a
3-phase 380V480V system. Unlike the previous VSR23 models built on the small Frame 1 setup, this 380V model transitions into the
Frame Size 2 (VSR2) enclosure footprint to accommodate higher voltage internal insulation clearances. [

Integrated System Protections
- Dual Motor Support: Capable of running both standard AC Induction Motors and highly efficient Permanent Magnet Synchronous Motors (PMSM). [1]
- Extreme Voltage Handling: Built-in high-threshold lightning protection, transient overvoltage clipping, and phase-loss isolation safeguards.
- Sensorless Automation: Advanced sleep and wake cycles tied directly to the solar radiance levels to eliminate manually switching power over during cloudy intervals.
