FRONT PANEL CONTROLS (standard versions)
Voltage setting: Via single rotary controls for coarse and
fine control.
Current setting: Via single turn semi-logarithmic rotary
control.
Overvoltage setting: Via screwdriver adjustable preset poten
-
tiometer.
Output On/Off: Latchinh push-push switch operating
electronic power control.
FRONT PANEL CONTROLS (P versions)
Voltage setting: Direct keyboard entry or quasi-analogue
rotary control.
Current setting: Direct keyboard entry or quasi-analogue
rotary control.
Overvoltage setting: Direct keyboard entry.
Output On/Off: Push button control with indicator lamp
operating electronic power control.
Note: all voltage and current levels set via the keyboard are displayed
on a separate 0.3" 4 digit display. This entry preview system ensures
that the user can observe the value entered before it is effected thus
avoiding possible error. The display is also used for setting additional
functions and for displaying watts.
Additional keyboard functions:
Increase or decrease voltage or current in user-selectable steps
(delta mode). Store/recall voltage, current & OVP levels from
non-volatile memory (25 memories). Set digital interface type
(RS232 or GPIB), set baud rate, set address.
DIGITAL INTERFACES (P versions)
RS232:
Variable baud rate, 9600 baud maximum, 9 pin D connector
(male). Fully compatible with standard RS232 or TTi address-
able RS232 system (ARC).
IEEE-488 (GPIB): Conforming with IEEE488.1 & IEEE488.2.
Bus Functions: Set voltage; set current; set OVP; set output
On/Off; read output voltage/current.
Setting resolution: Voltage - 10mV; Current - 10mA.
Setting accuracy: Voltage - ±(0.1% + 10mV);
Current - ±(0.2% + 20mA).
Response times:
Interface - <15ms (single command);
PSU - Depends on Load conditions, typically 150ms to within
0.1% of final value (except for voltage reduction with low load
current which will be longer).
Readback resolution: Voltage - 10mV; Current - 10mA.
Readback accuracy: Voltage - ±(0.1% + 1 digit);
Current - ±(0.5% +1 digit).
Operating software:
Software for operating the PSUs under GPIB or RS232 control
is available including a Labwindows* driver and ARC-TALK
software for a PC.
