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.

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 General Description
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.
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.

2.2.1 ISOLATED ANALOG PROGRAMMER Functions
The following sections describe the functions of the various signals of the ISOLATED ANALOG
Programmer. Circuit is SELV, and all connections have electrical isolation from the output of the
unit. Pin numbers correspond to the rear panel J4 connector pin out of Table 2–2.
Digital Control Input Signals
ANALOG-CONTROL (Remote/Local): Pin-1, enables remote analog programming with an
active-low logic level. When a low level is applied, the supply will power-up with the analog
interface in control of the output voltage. When high, the power supply will be in local control
mode. Signal return is at J4-2.
EXTERNAL SHUT DOWN (S/D): Pin-14, disables the output when applied and supply is
working in the Remote Control mode. Logic level can be selected with switch SW1-6 to be
active high or low. Signal return is at J4-2.
Digital Control Status Output Signals
VOLTAGE-MODE: Pin-5, nominal 5VDC logic level indicates operation in constant-voltage
mode. Low logic level indicates operation in constant current mode. Signal return is at J4-2.
OVP: Pin-17, nominal 5VDC logic level indicates that the output has been disabled because of
overvoltage protection. Signal return is at J4-2.
FAULT: Pin-18, nominal 5VDC logic level indicates that the output is disabled because of an
over temperature or shutdown fault. Signal return is at J4-2.
Analog Monitor Signals
VOLTAGE MONITOR, 0-5/10V: Pin-19, provides an analog readback of the output voltage
with a 0-5VDC or 0-10VDC signal (user selectable with switch SW1-4) indicating 0-100% of full
scale output. Signal is referenced to J4-6.
VOLTAGE MONITOR, 4-20mA: Pin-4, provides an analog readback of the output voltage with
a 4-20mA signal indicating 0-100% of full scale output. Signal return for the 4-20mA current is
J4-6.
CURRENT MONITOR, 0-5/10V: Pin-7, provides an analog readback of the output current with
a 0-5VDC or 0-10VDC signal (user selectable with switch SW1-5) indicating 0-100% of full scale

Signal return is at J4-12.
Note: The OVP input is programmed to 110% by an internal connection between the 1mA
source on Pin-16 to a separate circuit. This allows the user to program remotely without having
to provide a separate programming source or jumper to the OVP input.

programs the output voltage from 0-100% of full scale.

output voltage from 0-100% of full scale. Signal return is at J4-12.
b) An input signal of 4-20mA (with switch SW1-1 set to ON (1) position, programs the output
voltage from 0-100% of full scale. Jumpers from J4-25 to J4-12 and J4-20 to J4-8 are also
required. Signal return for the 4-20mA current is J4-25.
CURRENT PROGRAMMING INPUT: Pin-10, an input signal of 0-5 volts, 0-10 volts or 4-20mA
programs the output current from 0-100% of full scale.

required. Signal return for the 4-20mA current is J4-23.
OVP RESISTANCE PROGRAMMING OUTPUT: Pin-16, provides a 1mA current source which
when connected to Pin-3, the OVP PROG INPUT, with a 0-10KΩ external resistor connected
between Pin-16 and Pin-12, programs the OVP threshold from 5-110% of full scale output
voltage. Switch SW1-3 must be set to ON (1) to select 0-5VDC input range.
Note: The OVP input is programmed to 110% by an internal connection between the 1mA
source on Pin-16 to a separate circuit. This allows the user to program remotely without having
to provide a separate programming source or jumper to the OVP input.
VOLTAGE RESISTANCE PROGRAMMING OUTPUT: Pin-21, provides a 1mA current source

1. Set SW1-1, V PROG, to ON (1) for 4-20mA programming range.
2. Connect the external programming current source to the ISOLATED ANALOG
PROGRAMMER connector, J4, with the source to Pin-9 and the return to Pin-25.
3. Connect a jumper from Pin-25 to Pin-12 to connect the 4-20mA current sense resistors
to common.
4. Connect a jumper from Pin 20 to Pin 8 to provide the negative 2.5VDC to zero out the
4mA signal generated by internal circuits.
5. Connect Pin-1, ANALOG-CONTROL, of the ISOLATED ANALOG PROGRAMMER
connector, J4, to Pin-2 to enable remote control.
6. Program the other parameters to the desired limit values.

2.4 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 2–3 for information on
configuring the monitors.
