Mecer Astro 0.75kW Variable Frequency Drive 380V

Astro 0.75kW VFD

The Mecer Astro 0.75kW variable frequency drive regulates three-phase motor speed for pumps, fans, and conveyors that need efficient flow control without mechanical throttling. It accepts 380 V AC three-phase input and outputs PWM-controlled voltage to 0.75 kW induction motors while providing built-in protection and parameter tuning for industrial automation panels. V/f control with selectable curves supports both constant torque and variable torque load profiles on standard factory distribution. Overcurrent, overvoltage, undervoltage, and thermal safeguards trip before insulation or bearing damage occurs on downstream motors. RS-485 Modbus RTU communication enables remote monitoring and setpoint changes from SCADA and BMS supervisory systems.

Key Features

• 0.75 kW Motor Control Rating
  Sized for small pumps, ventilation fans, and packaging line drives where precise speed adjustment cuts energy use.

• 380 V Three-Phase Input

  • Compatible with standard industrial three-phase distribution common in factory and plant environments.
  • Supports constant torque and variable torque load profiles through adjustable V/f curves.
  • Input voltage tolerance accommodates typical plant bus fluctuations without nuisance fault trips.

• Integrated Protection Functions
  Overcurrent, overvoltage, undervoltage, and thermal overload safeguards reduce downstream motor and mechanical failures.

• Parameter Configuration Interface

  • Keypad and digital inputs enable local speed reference and start/stop control without a separate PLC in simple loops.
  • RS-485 Modbus communication option supports SCADA and BMS integration on networked lines.
  • Multi-step speed presets allow staged ramp profiles for conveyor and mixer applications.

• 150 Percent Overload Capacity
  Drive delivers 150 percent rated current for 60 seconds to handle brief startup torque demands on loaded pumps.

Why Choose Astro 0.75kW

• Variable speed control lowers energy draw on fan and pump loads compared to damper or valve throttling.

• 380 V three-phase input aligns with standard industrial motor supply without step-down transformers.

• Built-in protections extend motor and mechanical component life in unattended equipment rooms.

• Compact panel-mount form factor fits existing control cabinets during retrofit projects.

• Modbus RTU connectivity integrates the drive into existing plant SCADA without proprietary gateways.

• Local keypad programming reduces commissioning time on standalone fan and pump loops.
