AVSL 650.676 REGULATED DC POWER SUPPLY - Manual

Front Panel
1. Power switch: ON/OFF the power
2. Output standby: After power on, there are no voltage cross the terminals. Press this button, output LED on, unit has power out.
Repress this button, output LED off, output voltage cross the terminals is zero, unit is on standby mode.
3. Output standby indicator: See above.
4. C.C. indicator Lights when the supply is in the constant current operation.
5. C.V. indicator: Lights when the supply is in the constant voltage operation.
6. Voltmeter: lndicates the output voltage.
7. Ammeter: lndicates the output current.
8. Voltage Coarse: For coarse adjustment of the output voltage.
9. Voltage Fine: For fine adjustment of the output voltage.
10. Current Coarse: For coarse adjustment of the output current.
11. Current Fine: For fine adjustment of the output current.
12. “+” Output terminal: positive polarity (red)
13. “GND” terminal: Earth and chassis ground (green)
14. “–” Output terminal: Negative polarity (black)

INTRODUCTION
These regulated DC power supply are designed to provide the
required voltage and current source in laboratory, university and
production lines.
The output voltage is continuously adjustable between 0 to rating
voltage. The load current may have any value from 0 to rating
current. Voltage and Current are adjusted by means of a coarse
and fine potentiometer.Both outputs can accurately read on
voltmeter and ammeter LED displays.
Both stability and ripple are extremely good to meet the
requirements of modern circuit design. The unit can be used
as either constant voltage or current source. They have output
standby function, a four digit LED display and overload protection
circuits.
