About this product
Hoyt 1000:1 current transformer for analog and digital AC panel meters measuring up to 100 amps. The measured conductor passes through the 0.80-inch solid-core window, and the transformer supplies a 100 mA AC maximum secondary signal at the rated 100 A primary current.
Its fully encapsulated construction, 18-inch 18 AWG signal leads, and −40 to 80 °C operating range suit marine electrical panels, generator monitoring, and shore-power applications.
