Sensitivity Control

Sensitivity adjustment prevents LTC transformers from hunting or being several

steps apart.

Sensitivity is adjustable from two times normal to 0.5 times normal in nine steps.

Parallel/Independent Switch

Mode of LTC control is switch selectable.

Transient Protection

Input and output circuits are protected against system transients. The M‑0115A

will exhibit no component failure or false commands when subjected to the

requirements of ANSI/IEEE C37.90.1-1989. which defines oscillatory and fast

transient surge withstand capability. All inputs and outputs will withstand 1500

Vac to chassis or instrument ground for one minute. Voltage inputs are electrically

isolated from each other, from other circuits, and from ground.

Mounting

Panel mounted using 8‑1/2″ x 6‑1/8″ cutout (21.59 cm x 15.56 cm). May be

surface mounted using the M‑0124 Surface Mounting Adapter.

Application

This manual includes an overview of typical system setup and connections, necessary

components, and the information necessary to implement a paralleling scheme using

the M‑0115A in the Circulating Current paralleling method.
