6.2.1 Frequency Setting The range for the frequency setting of the 3A Series load is either DC or from 0.1 to 400 Hz. If a value below 40Hz is entered, the frequency setting will automatically be set to DC. Setting the expected AC frequency of the AC input voltage allows the 3A Series load to synchronize to it properly using its internal synchronization circuits.
