4.2 FRONT PANEL DESCRIPTION
Figure 4.1 shows layout of front panel. On the front panel following controls and
indicators are provided.
1. Main ON/OFF switch with neon indication.
2. 3 digit display for Voltage/ Set Voltage/ Set Over Voltage indication
3. 3 digit display for Current/ Set Current indication.
4. 10 turn POT for voltage control.
5. 10 turn POT for current control.
6. 10 turn POT for over voltage protection control.
7. Push switch to view set parameters in SET mode.
8. Latch type Push switch for Output ON/OFF control.
9. LED indications for CV, CC, Output ON, Trip, Remote, V set, I set, O/V set and
Set mode.
- The display shows 3 digit value for voltage and current parameters. The resolution of
indication is 0.1 volt and 0.1 amp for voltage and current parameters. The display is
used to show actual output voltage and current or to show set values of voltage, over
voltage and set current limit in the set mode. The set mode is activated using Set key
during output OFF condition.
- CV LED indicates the constant voltage operation of power supply.
- CC LED indicates constant current operation of power supply.
- TRIP LED becomes ON either for over voltage trip condition or for over temperature
trip condition.
- Output ON/OFF can be controlled by push button switch (latch type) and LED turns
ON if output is available.
- Remote LED is provided for the digital interface option. It lights up when the power
supply is controlled by external digital interface.
- To view the set values of POT on the display press the SET key. Also LED’s for
each POT and common SET MODE Led is provided.
- Also monitoring terminals of output are provided on front panel so that user can verify
the output with calibrated meter. Additional earth terminal is also provided on front
panel.
4.3 REAR PANEL DESCRIPTION
The rear panel of the unit is shown in fig 4.2. The mains input connection is
made through a mains cord and is located on the right side of the unit at the rear.
A 20A fuse of type ’F’ is used for line input range 95Vac to 264Vac,) provided at input.
At the center are the oval shaped ventilation slots for air exhaust, for D.C. output 5mm
brass studs or bus bars (as per the current specifications) are provided, next to
it is 6 way terminal block for remote sensing and current share bus. Further is the 25
pin D-type connector for analog interfacing & the associated 8 pin DIP switch for
selection of analog mode operation and it’s associated modes of operation. Above the
25 pin D-type connector the provision is made for digital interface connection, which
can be either GPIB or RS232.
