SAFETY NOTICE

Before applying power to the system, verify that the instrument is configured properly for the user’s
particular application.

WARNING!

Hazardous voltages may be present when covers are
removed. Qualified personnel must use extreme caution
when servicing this equipment. Circuit boards, test points,
and output voltages also may be floating with respect to
chassis ground.

Installation and servicing must be performed by qualified personnel who are aware of dealing
properly with attendant hazards. This includes such simple tasks as fuse verification.

Ensure that the AC power line ground is connected properly to the chassis. Similarly, other
power ground lines including those to application and maintenance equipment must
properly for both personnel and equipment safety.

be grounded

Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any
cable.

In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/user must
ensure that the output power lines are labeled properly as to the safety hazards and that any
inadvertent contact with hazardous voltages is eliminated.

Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety
glasses during open cover checks to avoid personal injury by any sudden component failure.

Some circuits are live even with the front panel switch turned off. Service, fuse verification, and
connection of wiring to the chassis must be accomplished at least five minutes after power has
been removed via external means; all circuits and/or terminals to be touched must be safety
grounded to the chassis.

These operating instructions form an integral part of the equipment and must be available to the
operating personnel at all times. All the safety instructions and advice notes are to be followed.

Neither Elgar Electronics Corporation, San Diego, California, USA, nor any of the subsidiary sales
organizations can accept any responsibility for incidental or consequential injury of personnel, or
loss or damage of equipment or material that results from improper use of the equipment and

accessories.

SECTION 1

M51A OPTION OVERVIEW

1.1 Introduction

This manual is to be used in conjunction with the DCS-E 1kW Series & DCS-E 1.2kW Series
DC Power Supplies Operation Manual, Sorensen Document No. M362500-01 and the DLM-E
3Kw & 4Kw Series Power Supplies Operation Manual, Sorensen Document No. M362000-01.

The Sorensen M51A Option provides a remote isolated analog programming interface, which
has safety isolation from the output terminals. This allows the remote analog interface to be
connected to user–accessible, Safety Extra Low Voltage, (SELV) control circuits, even though
the output terminals are floated at a high potential with respect to the chassis.

1.2

The M51A Option provides isolation for all programming, monitoring, and digital I/O signals that
are available through the standard rear panel analog interface connector. This isolation barrier
eliminates the connection that exists in the standard models between the non-isolated remote
interface circuits and the power supplies output return (negative) terminal. All control and
monitoring signals on the M51A option are optically coupled from the power supply output, and
can are user accessible irrespective of the float potentials that could exist at the output
terminals.

General Description

The M51A Option provides a full complement of programming, monitoring, and control
functions. 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 and connector jumpers. The output voltage, current, and OVP can be programmed
with a 0-5VDC, 0-10VDC, or 0-5kΩ resistance; in addition, the output voltage and current can
be programmed with 4-20mA signals. The output voltage and current monitors can 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 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.

PROGRAMMER OPERATION

2.1

The SW1 SETUP switch is accessible from the rear panel of the unit. It provides user selection
of the programming/monitoring ranges and shutdown logic signal level. Setting a switch to the 1
or 0 position changes a range. The factory default settings are shown below.

Refer to Figure 2–1 for a rear panel view of the DLM-E 3kW and 4kW models.
Refer to Figure 2–2 for a rear panel view of the DCS-E 1kW models.
