Description of Options
E designates LW models with improved EMC performance.
Refer to the EC Declaration of Conformity (last page). Feature
E is standard for new designs.
Single options D1, D2, D5, R are available (as single choice
options) on the AUX terminal (10), referenced to Vo–.
Option M1 and M2 designate a combination of several options
accessible via a D-SUB connector. Option M1 includes the
function SD (shutdown).
Single Options Using the AUX Pin
The connection is shown in the figure below. For the
description refer to Adjustment of V
Multiple Options M1 or M2 via D-SUB Connector
The option board is suitable for applications, where several
options are needed. Option M1 is standard for battery charger
models, option M2 is suitable for applications without battery or
for simple applications with battery.
