Mecer Astro 1.5kW Variable Frequency Drive 380V

Astro 1.5kW VFD

The Mecer Astro 1.5kW drive delivers PWM-based speed control for 1.5 kW three-phase induction motors on HVAC, water treatment, and material handling equipment. It operates from 380 V AC three-phase mains and provides programmable acceleration ramps, fault diagnostics, and communication options suited to panel builders and maintenance engineers. V/f control with multi-step speed presets supports staged ramp profiles on conveyors, mixers, and booster pumps. Digital and analog I/O accept speed references from PLCs, pressure transducers, and local potentiometers without additional signal conditioning modules. RS-485 Modbus RTU interface enables remote monitoring and setpoint changes from supervisory BMS and SCADA platforms.

Key Features

• 1.5 kW Continuous Output Rating
  Handles mid-size fan, pump, and conveyor motors where fixed-speed operation wastes energy at partial load conditions.

• 380 V Three-Phase Supply

  • Matches common industrial distribution without additional voltage conversion hardware.
  • Supports both variable torque and constant torque applications through adjustable control modes.
  • Input filtering reduces nuisance trips from moderate mains distortion on older plant bus networks.

• Comprehensive Motor Protection
  Monitors overcurrent, bus voltage excursions, and heatsink temperature to trip before insulation or bearing damage occurs.

• Flexible Control and Networking

  • Digital and analog I/O accept speed references from PLCs, pressure transducers, and local potentiometers.
  • RS-485 Modbus RTU interface enables remote monitoring and setpoint changes from supervisory systems.
  • Programmable acceleration and deceleration ramps reduce mechanical shock on belts and couplings at startup.

• 150 Percent Overload Headroom
  Drive sustains 150 percent rated current for 60 seconds to overcome inertia loads on larger fan and pump impellers.

Why Choose Astro 1.5kW

• Higher 1.5 kW rating supports larger pumps and fans while retaining compact panel footprint.

• 380 V input integrates directly with standard three-phase plant wiring during retrofits.

• Programmable ramps reduce mechanical shock on belts, couplings, and gearboxes at startup.

• Modbus connectivity simplifies integration into existing BMS and SCADA monitoring infrastructure.

• Analog speed reference input supports closed-loop pressure control on booster pump skids.

• Fault diagnostic codes on the front display accelerate field troubleshooting during production outages.
