The Sorensen M51A Option for the DLM 600W Series power supplies provides a remote analog
interface, which has safety isolation from the output terminals. This allows the remote analog
interface to be connected to user accessible (SELV) control circuits, even though the output
terminals were floated at a high potential with respect to the chassis.
interface, which has safety isolation from the output terminals. This allows the remote analog
interface to be connected to user accessible (SELV) control circuits, even though the output
terminals were floated at a high potential with respect to the chassis.
General Description
The M51A Option provides isolation for all programming, monitoring, and digital I/O signals that
are available through the remote analog interface. This isolation barrier eliminates the
connection that exists in the standard DLM models between the non-isolated remote interface
circuits and the output return (negative) terminal. The M51A Option remote analog signals are
referenced to chassis, and could be user accessible irrespective of the float potentials that exist
at the output terminals.

referenced to chassis, and could be user accessible irrespective of the float potentials that exist

The M51A Option provides a full complement of programming, monitoring, and control methods.
Remote programming is available for output voltage, current, and overvoltage protection (OVP).
Analog output monitor signals are available for the output voltage and current. Digital I/O
signals provide indication of the operational state, and a means of enabling the remote interface
and the output.

The type and range of the control and monitor signals are user-selectable with a rear panel
setup switch. The output voltage, current, and OVP could be programmed with a 0-5VDC,
0-10VDC, or 0-5kΩ resistance; in addition, the output voltage and current could be programmed
with 4-20mA signals. The output voltage and current monitors could produce 0-5VDC,
0-10VDC, or 4-20mA signals. Isolated 1mA current sources are provided to facilitate the
utilization of 0-5kΩ programming resistances.

Except for the isolated remote analog interface, the installation and operation of the DLM 600W
Series power supplies remains as presented in the Operation Manual. The following sections
provide a detailed description of the new features and the differences in operation.
