What to look for in surge protection for power supplies
By Ron Stull, CUI, Inc. Any mains-powered electrical device is vulnerable to voltage surge. These completely unpredictable events can take many forms: from modest power spikes during normal operation to massive power surges caused by an external lightning strike. To prevent damage and downtime, electrical equipment and circuits need to be provided with adequate surge […]
