Current Generators

DOC Series



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

Breaker switching equipment ON and OFF
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
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
Alarm for over temperature of power circuit putting Power
Supply in stand- by with an alarm LED lighting up
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
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”
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
“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


interface to program the Power Supply with standard IEEE488/RS232
interface to program the Power Supply with standard IEEE488/RS485
reaction to remote programming up to 8 A/µs
3-phase mains input, in models with output power less than 2400 W
