Installation DLM-E 3kW & 4kW Series Power Supplies
2-4 M362000-01 Rev E
2.4.1 Front Panel User Controls and Indicators
1. CURRENT knob: 10 turn adjustment sets the output current.
2. VOLTAGE knob: 10 turn adjustment sets the output voltage.
3. OVP SET potentiometer: 20 turn trim pot recessed behind front panel sets the over
voltage trip limit.
4. POWER switch: Two–position switch enables or disables the supply.
5. ENABLE/STANDBY switch: Two–position switch allows the unit to be placed in an
active (enabled) or inactive (standby) mode. The front panel displays are still active in
the STANDBY mode.
6. LOCAL/REMOTE switch: Two–position switch selects if the front panel VOLTAGE,
CURRENT and OVP controls (local) or the analog programming inputs from the rear
panel J3 connector (remote) will determine the output settings for the supply.
7. PREVIEW switches: Two momentary push button switches. While in the STANDBY
mode, the V&I button will display the output voltage and current settings prior to power
being applied to the load. The OVP button will display the over voltage shutdown set
point. Local or remote signal preview settings are selectable with the LOCAL/REMOTE
mode switch position.
8. VOLTAGE DISPLAY: 3½ digit green LED display normally indicates DC output voltage
of supply. Indicates preset output voltage setting when the V&I PREVIEW button is
pushed and indicates the OVP setting when the OVP PREVIEW button is pushed.
9. VOLTAGE MODE indicator: Green LED lights when in the constant–voltage mode of
operation. When in the constant voltage mode, the output voltage will regulate to the set
value and the current value will vary with the load.
10. CURRENT MODE indicator: Green LED lights when in the constant–current mode of
operation. When in the constant current mode, the output current will regulate to the set
value and the output voltage will vary with the load.
11. CURRENT DISPLAY: 3½ digit green LED display normally indicates DC output current
of supply. Push the V&I PREVIEW button to display preset output current setting.
12. ON (AC Input Power ON) indicator: Yellow LED lights when power switch is on and AC
is applied. (Note: this LED does NOT indicate DC output status.)
13. S/D (Shutdown) indicator: Red LED lights when the unit has been shutdown remotely.
14. REM (Remote) indicator: Green LED lights when unit is in remote programming mode.
15. OVP (Over Voltage Protection) indicator: Red LED lights when an over voltage
shutdown has occurred.
