c) Control via controllable resistance (potentiometer)
The power supply can be remote controlled with an external potentiometer (5 kOhm) over the entire range for
voltage and current.
Connect the connection lines to the remote sockets as illustrated.
Voltage setting “V” Current setting “I“:
• Connection 1 at one end of the resistor. • Connection 1 at the end of the resistor.
• Connection 2 at the middle sliding contact of the
resistor.
• Connection 3 at the middle sliding contact of the
resistor.
• Connection 4 at the second end of the resistor. • Connection 4 at the second end of the resistor.
The connections 1 and 4 should not be short circuited.
d) output remote control (on/off)
The DC output can be switched on and off via a switch contact. Proceed as follows for the connection:
1. Connect the connection lines to the remote sockets as illustrated.
2. Connect the 4 and 5 connection to a potential free switch contact.
3. The status displays
C.V. and C.C. flash when the output is switched off. In addition the display (2) indicates the
current settings of the output voltage and output current.
4. You can determine the output values with the setting controller for voltage VoLTAgE (4) and current limitation
CurrENT (5) when the output is switched off.
No voltage should be applied t contacts 4 and 5.
