DANA DSOT Series Linear Electronic Load 0 Volt Front Panel

 

FRONT PANEL CONTROLS

Power
switches ON and OFF the device

Stand-by
switch that enables the device to carry out the functions which are armed.

Function
V – R – A – P slide switches to enable the device to carry out the select functions ( functions V and P are optional).

GPAC – GPIB / RS
slide switches to select the interface used for remote programming. GPAC, analog programming between 0 – 10 Vdc and feedback 0 – 10 Vdc. GPIB (option), programming by an interface IEEE488 –
RS232/485.

Remote controls
V – R – A – P slide switches to set programming mode of functions in local o remote mode.

Check
push button to setting the functions when the device is in stand-by, suitable also with remote programming.

GND
ground connector

+/-
input plugs available also on back panel.

Section Vin (optional)
10 turns potentiometer to calibrate the input chosen work voltage. Voltage input digital display (with accuracy ±1,5%)

Section R
10 turns potentiometer to calibrate the chosen work resistance. Work resistance digital display (with accuracy ±1,5%)

Section A
10 turns potentiometer to calibrate the input chosen work current. Work current digital display (with accuracy ±1,5%)

Section P (optional)
10 turns potentiometer to calibrate max input chosen work power. Work power digital display (with accuracy ±1,5%)

APP
alarm LED of inversion polarity of power cables with immediately inhibits of device.

OVP
alarm LED that indicates the overcoming of maximum voltage work admitted on input.
Its intervention inhibits the device.

OT
alarm LED for over temperature on the power section, its intervention inhibit the device

BACK PANEL CONTROLS

GPAC
“General Purpose Analogical Control” connector to be used to control electronic load adjustments with 0 – 10
Vdc analog voltage for all remote functions and to read all functions feed-back

GPIB/RS (option)
Connectors to program interface IEEE488 and RS232/485
+/-
input plugs available also on the front panel

OPTIONS

PS
