Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your
particular application.
WARNIN
WARNIN
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
Ensure that the AC power line ground is connected properly to the Power Rack input connector or
chassis. Similarly, other power ground lines including those to application and maintenance
equipment must be grounded properly for both personnel and equipment safety.
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.
Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary
sales organizations can accept any responsibility for personnel, material or inconsequential injury,
loss or damage that results from improper use of the equipment and accessories.
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 above
(below) chassis ground.
The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.

SECTION 1
M51A OPTION OVERVIEW
1.1 Introduction
This addendum is to be used in conjunction with the DLM 600W Series Power Supplies
Operation Manual, Sorensen Document No. M362161-01.
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.
1.2 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.
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.

1. Set Position-2, I, of the INTFC SETUP switch to OFF (down) for 0-5VDC programming
range.
2. Connect the external programming resistance, 0-5kΩ, to the ISOLATED ANALOG
INTERFACE connector, from Pin-22 to Pin-12.
3. Connect a jumper from Pin-22 to Pin-10.
4. Program the other parameters to the desired limit values: VOLTAGE PROGRAMMING
INPUT, Pin-9, and the OVP PROGRAMMING INPUT, Pin-3, with respect to Pin-12.
5. Connect Pin-1, ANALOG-CONTROL, of the ISOLATED ANALOG INTERFACE
connector to Pin-15.

2.4.6 Resistance Programming of OVP
Setting up for resistance programming OVP is as follows:
1. Set Position-3, OVP, of the INTFC SETUP switch to OFF (down) for 0-5VDC
programming range.
2. Connect the external programming resistance, 0-5kΩ, to the ISOLATED ANALOG
INTERFACE connector, from Pin-16 to Pin-12.
3. Connect a jumper from Pin-16 to Pin-3.
4. Program the other parameters to the desired limit values: VOLTAGE PROGRAMMING
INPUT, Pin-9, and the CURRENT PROGRAMMING INPUT, Pin-10, with respect to pin-
12.
5. Connect Pin-1, ANALOG-CONTROL, of the ISOLATED ANALOG INTERFACE
connector to Pin-15.
2.4.7 4-20mA Current Source Programming of Output Voltage
Setting up for 4-20mA programming of the output voltage is as follows:
1. Set Position-1, V, of the INTFC SETUP switch to OFF (down) for 0-5VDC programming
range.
2. Connect the external 4-20mA programming current source to the ISOLATED ANALOG
INTERFACE connector, with source at Pin-9 and return at Pin-25.
3. Connect a jumper from Pin-25 to Pin-12.
4. Connect a jumper from Pin-8 to Pin-20.
5. Program the other parameters to the desired limit values: CURRENT PROGRAMMING
INPUT, Pin-10, and the OVP PROGRAMMING INPUT, Pin-3, with respect to pin-12.
6. Connect Pin-1, ANALOG-CONTROL, of the ISOLATED ANALOG INTERFACE
connector to Pin-15.
2.4.8 4-20mA Current Source Programming of Output Current
Setting up for 4-20mA programming of the output current is as follows:
1. Set Position-2, I, of the INTFC SETUP switch to OFF (down) for 0-5VDC programming
range.
2. Connect the external 4-20mA programming current source to the ISOLATED ANALOG
INTERFACE connector, with source at Pin-10 and return at Pin-13.

3. Connect a jumper from Pin-13 to Pin-12.
4. Connect a jumper from Pin-11 to Pin-23.
5. Program the other parameters to the desired limit values: VOLTAGE PROGRAMMING
INPUT, Pin-9, and the OVP PROGRAMMING INPUT, Pin-3, with respect to pin-12.
6. Connect Pin-1, ANALOG-CONTROL, of the ISOLATED ANALOG INTERFACE
connector to Pin-15.
2.5 EXTERNAL-OFF Control
The EXTERNAL-OFF control input provides the same functionality as the OUTPUT switch on
the front panel. When asserted, it will turn off the output converter, discharge the output
capacitors with the downprogrammer, and reset the OVP and FAULT monitors. The signal
could be configured to be either active-low or active-high with the INTFC SETUP switch on the
rear panel.
Set Position-6, /EXT-OFF, to the OFF (down) position to select the active-high logic level for
asserting EXTERNAL-OFF. Set Position-6, /EXT-OFF, to the ON (up) position to select the
active-low logic level for asserting EXTERNAL-OFF. The logic-high level could be produced
with a voltage source within the range of 3-30VDC, and would be connected to Pin14, positive,
and Pin-2, return. The circuit is SELV, and has electrical isolation from the output of the unit.
2.6 Remote Monitoring
Analog signals are available for monitoring the output voltage and current. These signals vary
proportionally to the output parameters, and have user selectable ranges of 0-5VDC, 0-10VDC,
or 4-20mA for an output change from zero to full scale. Refer to Table 2–4 for information on
configuring the monitors.
