Static Frequency Converter

Three Phase Input System with Three Phase Output 10kVA – 300kVA

Red Box International 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.

Red Box International Static Frequency Converters are available in a wide power range and include an output isolation transformer as standard. The design offers 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 Red Box International RBC series provides flexibility, efficiency and compatibility in applications where high quality wave shape is a critical factor.

Harmonics BS EN 61000-3-4
System Operation The Power Factor Corrected rectifier converts the single or three phase mains supply into DC, the PWM inverter switches the DC back to AC at the desired frequency and voltage, the output transformer provides Galvanic Isolation which isolates the input and output from each other. The output neutral is bonded to earth for safety.
PROTECTIONS:
Overload Protection The system provides electronic overload protection to protect the system from excessive loading. Standard overloads settings allow for 121% for 2 minutes and 160% for 5 seconds.
Short-Circuit Protection The system provides electronic short circuit protection by combination of IGBT saturation detection and peak current limiting.
Fault Clearance The system has a high fault clearance capability, as a general rule the system can clear a load circuit breaker of typically one third of the output current (C Curve). Designers should bear this in mind when calculating fault discrimination.
Overvoltage Protection The system provides over voltage protection by monitoring input and output voltages electronically and shutting down the system to prevent damage. In addition, surge arrestors are fitted to the input and output for additional protection.
Phase Rotation Detection On three phase input systems, the phase rotation is checked before initialising the rectifier to ensure phase rotation is correct (clockwise).
