RMI-P Series Inverter

RMI-P Series Inverter

Product catalog summary
Overview: The RMI-P Series Inverter is a hot-swap, high-frequency modular inverter designed for parallel operation with a 220VAC output, ranging from 1 to 24KVA. It features advanced digital control and a robust design for high reliability and flexibility.
Key Features:
  • Digital Control: Utilizes 32-bit DSP full digital and high-frequency SPWM technology for strong anti-interference, fast processing, and precise control.
  • N+1 Parallel Redundant Design: Allows for a redundant power supply system with modules backing each other up, ensuring high reliability.
  • No Master-Slave Parallel Technology: Each module operates independently, eliminating single points of failure.
  • Module Built-in Bypass: Users can select between inverter priority or bypass priority.
  • Hot Plugging: Modules are plug-and-play, simplifying maintenance and replacement.
  • Monitoring Management: Includes an indicator panel, fault alarms, RS485 communication interface, and fault dry contact.
  • Protection Functions: Features input and output over-voltage protection, over-temperature protection, and short-circuit protection.
  • High Power Density: Compact design saves space and facilitates parallel configuration.
Specifications:
  • Rated Power: Available in 1KVA, 2KVA, and 3KVA models.
  • DC Input Voltage: 48VDC/220VDC with a range of 42-59VDC/190-270VDC.
  • Bypass Input Range: Adjustable between 176-264V.
  • Output Voltage and Frequency: 220VAC at 50Hz.
  • Load Regulation and Frequency Accuracy: Less than 1% and 0.1% respectively.
  • Waveform Distortion: Resistance full load less than 3%, nonlinear full load less than 5%.
  • Dynamic Response: Voltage transient range less than 3%, recovery time within 60ms.
  • Operating Environment: Temperature range from -10 to 50°C, storage temperature from -40 to 70°C, and relative humidity from 0 to 90% without condensation.
  • Noise Level: Less than 45dB at 1 meter.
  • Overload Capacity: Varies with load current, with specific shutdown times for different overload percentages.

The modules are backup each other, with high reliability and flexible configuration. No master-slave parallel technology: the operation and parallel connection of each module are independently controlled by the built-in DSP, no single point of failure, independent flow between modules. Input connection protection, Protection Function output short circuit protection, over temperature protection Module built-in bypass: users can choose inverter priority or bypass priority. Communication input under voltage and over-voltage protection, output overload protection, Communication Interface With hot plugging: no need to do any parameter setting and operation, plug and play, the module automatically enters the normal working state, maintenance and replacement is simple and fast. Insulation Strength Monitoring management: indicator panel, fault sound and light alarm, RS485 communication interface and fault dry contact. Operating Ambient Protection function: it has the functions of input over-voltage, output over-voltage, overtemperature, short-circuit and so on. High power density: 1/2 19〞 width design, the volume is only half the width of the conventional inverter, saving space and convenient parallel.
