DANA DAC Series Linear Continuous Current Generator Front Panel

With same project philosophy of “DA” series Power Supply, without changing front side look and programming commands, we added to our catalog this family of Current Generators. Rise and fall rate of output current are among most interesting features of this equipment affording same characteristics of a first class Power Supply.

FRONT PANEL CONTROLS

Power
Breaker switching equipment ON and OFF

DC
Commands allowing to hold power supply in stand-by and to make it supply according to need while a LED shows selected function
P – slider switch enabling DC output in permanent mode
(up to output voltage of 60 Vdc)
S – push-button to be used to avoid “DC” output when
Power switch is on

Check
V – A – OVP set up push-buttons when the Power Supply is in stand-by

OVP (Over Voltage Protection)
trimmer allowing to set up “hazard-limit” for the EUT, when picked it up inhibits Power Supply with an alarm LED lighting up

OT
Alarm for over temperature of power circuit putting Power Supply in stand- by with an alarm LED lighting up

Local/Remote
V/A – slide switches to select voltage and current programming mode through the front panel potentiometers (Local) or a remote command between 0÷10 Vdc through the GPAC connector or GPIB/RS interface (option)
DC – slide switch to program the DC supply from the panel control (Local) or from a remote command through the GPAC or GPIB

GPAC/GPIB
Slide switches enabling the power supply to be programmed by an analog voltage (0÷10 Vdc) through the GPAC connector on the back or through an IEEE488 – RS232/485 interface (optional)

Section V
Potentiometer and display (with accuracy of 1.5%) showing output voltage or, by means of Check button, programmed voltage.
LED of “voltage mode”

Inhibit Alarm LED with output inhibition showing the absence of one phase in models with 3-phase mains input or available for an alarm of a parameter chosen by the customer
Section A
Potentiometer and display (with accuracy of 1.5%) showing output current or, by means of Check button, programmed current.
LED of “current mode”

 

GND GroundPlug

+/- Auxiliary plug to be used as test point up to 5 A max

 

BACK PANEL CONTROLS

Remote Sense
Terminal block allowing to switch “remote sense” circuit control from power output plugs to remote sense, to recover a max voltage drop of 0,5 V for cable

GPAC
“General Purpose Analog Control” connector to program remotely the Power Supply with 0÷10
Vdc analog optically isolated voltage for all functions, to read
Voltage and Current proportional feed-back (0÷10 Vdc)
and to enable “DC” output through a logic signal (0 – 5V)
+/-
Power output

OPTIONS

PS
interface to program the Power Supply with standard IEEE488/RS232

PW
interface to program the Power Supply with standard IEEE488/RS485

T
reaction to remote programming up to 8 A/µs

Y
3-phase mains input, in models with output power less than 2400 W

 

The models in the table are available with voltage and output current on customer request.
