INTRODUCTION TO THE DBT12
The DBT12 is a high performance Isolation Transformer designed to isolate and normalize the
shore power for reliable shipboard use.
Isolation is obtained through the use of a conservatively rated transformer compliant to the
requirements of ABYC E-11.7.2.8, and as such includes a full fault current shield. The
transformer also provides basic range normalization and a first level of electrical noise filtering
as shown in Figure 1.

Being a unit designed from the ground up specifically for the yachting industry, all efforts have
been made to produce a unit capable of sustaining the marine environment. All unit
components are packaged in single drip-proof, dust-resistant aluminum enclosure. Complete
maintenance and service can be provided with front and side access to the unit. Unit operation
is managed through one circuit breaker and the LCD display.
