Making the Connection
To make pin–to–pin connections:
1. Unsolder any unnecessary pin–to–pin jumpers as required by the application.
2. Solder new connections using any appropriate single bus wire such as AWG 20 to 24.
To connect external source leads, resistance leads, or monitoring lines:
3. Unsolder any unnecessary jumpers as required by the application.
4. Solder leads to the specified pin using the recommended wiring and/or grounding point
for the application. Pin, wiring, and grounding specifications for particular applications
can be found in Section 4. Advanced Operation except for remote sensing specifications
which are in Section 3.3 Using Remote Sensing.
NOTE
When the front panel LOCAL/REMOTE Switch is moved to REMOTE operation,
voltage, current, and OVP programming functions must be remotely programmed.
For clarity, only the connections for the function being described are shown in the
following figures.
4.3 Remote Programming of Output Voltage and
Current Limit
Remote programming allows control of the power supply's output voltage and/or current limit to
shift from local operation at the front panel voltage and current controls to external analog input
sources. As a programming source is varied, the power supply's output varies proportionally
over its output range.
The analog programming signals are connected to the rear panel J3 connector. To provide the
lowest noise performance, shielded–twisted pair wiring is recommended for making
connections from external circuits to the J3 connector. Use the shortest leads possible.
Ground the shield to pin 12 on the J3 connector or to the chassis via one of the J3 connector
screws.
CAUTION!
The remote programming input is internally referenced to the supply's
negative output. Do not connect remote programming input lines
(J3 pins 9 & 10) to the supply's positive output.
Remote Programming Options
The following table summarizes access options for programming output voltage and current limit
with the input scales supported for the DLM–E Series supply. Refer to Section 4.3.1 for a
procedure and a connection diagram for programming output voltage and current limit using the
REMOTE/LOCAL switch. Subsequent sections provide short procedures and diagram the J3
