Enerpro 25KVac Hipot Pulse Transformer for MVTB Trigger Board EP1061

Description

This is a Brand New Enerpro 25KVac Hipot Pulse Transformer for MVTB Trigger Board 38ZR8715 EP1061. This transformer has a DCR at the secondary of exactly 1 kilohm. The primary is at or around 0.13 Ohms @ 151.2 uH (with a Q-Factor of 11.69), taken at 1 KHz (which are the two leads at the base of the transformer). The pulse transformer is being used in Enerpro's line of medium-voltage converters. The following spec is from a converter that uses this transformer (remember, this isn't the datasheet for the transformer, but rather the datasheet for the
converter
that
uses
the transformer. The actual datasheet for the transformer was never printed, as it is a custom transformer):
