Product catalog summary
Overview: The document provides technical specifications and features of the Magnus Power ME3 range of Static Frequency Converters, which are designed for three-phase input and output systems ranging from 10kVA to 300kVA. These converters utilize high-frequency PWM technology with IGBT's to ensure high-quality output under various load conditions and include Power Factor Correction (PFC) to minimize input current and harmonic distortion.
Specifications:
  • Power Range: 10kVA to 300kVA with corresponding active and apparent output power.
  • Input: Three-phase, 400 VAC nominal input voltage with a tolerance of +/- 10% and a nominal frequency of 50Hz (+/-5%).
  • Output: Nominal output voltage options of 190/200/208 or 380/400/415V, with voltage adjustment capabilities. Output frequency options include 50/60/400Hz with frequency stability of 0.1Hz.
  • Environmental Conditions: Operating temperature range of 0-40°C, relative humidity up to 90% non-condensing, and maximum altitude of 1000m before derating.
Features:
  • Adjustable output frequency and voltage, sine wave output, microprocessor control, and modular design for improved reliability and serviceability.
  • Data logger capable of storing up to 200 alarms.
  • Optional features include high IP rating, RS232 interface, remote start/stop, emergency power off, battery backup (UPS), and built-in distribution.
Protections:
  • Overload protection allows for 121% overload for 2 minutes and 160% for 5 seconds.
  • Short circuit protection through IGBT saturation detection and peak current limiting.
  • Over voltage protection with electronic monitoring and surge arrestors.
  • Phase rotation detection ensures correct phase rotation before initializing the rectifier.
Standards: Compliance with safety standard BS EN 62040-1, EMC standard BS EN 62040-2, and harmonics standard BS EN 61000-3-4.
System Operation: The system converts AC to DC using a power factor corrected rectifier, then back to AC at the desired frequency and voltage using a PWM inverter. An output transformer provides galvanic isolation.
Enclosure: Made of Zintec sheet steel with options for rear and top cable entry, removable gland/back plates, and various enclosure dimensions based on power capacity.

ME3-1

Static Frequency Converter Three Phase Input System with Three Phase Output 10kVA - 300kVA Our Static Frequency Converters employ high frequency PWM technology (IGBT’s) to achieve a high quality output under all load conditions. The systems are designed with PFC (Power Factor Correction), thereby reducing input current and harmonic distortion. Our Static Frequency Converters are available in a wide power range and include an output isolation transformer as flexibility on the input as well as the output, and can be configured for a wide variety of voltages and frequencies. A comprehensive LCD display, control panel and data logger provide detailed and accurate status and control of the system. The ME3 S.F.C. provides flexibility, efficiency and compatibility in applications where high quality wave shape is a critical factor.
