Avoiding installation issues with PWM inverters

Avoiding installation issues with PWM inverters   Variable speed AC drives have become very popular because of their energy efficiency. Additionally, they offer flexible control of processes and machinery using maintenance-free AC motors. AC drives use power switching techniques and generate high rates of change of voltage. Most modern AC drives use voltage-source PWM inverters. […]

Extending electrical equipment life by reducing cabinet temperature

The reliability of electrical and electronic equipment is critical to most production plants. Heat induced equipment failures causes damage to expensive equipment, and loss of production due to downtime. Electrical equipment life is extended by operating at the correct cabinet temperature   The temperature inside an electrical cabinet is invariable higher than the ambient. The […]
