Model 1672 has two variable outputs, which can work independently
or in series tracking or parallel mode with pull and push switch ar-
rangements provided with master voltage and current control knobs.
Independent Mode
Ensure the master voltage and current control knobs are in PUSH condition to operate
the variable outputs independently.
Section 4
SETTING THE OUTPUT VOLTAGE AND OUTPUT CURRENT
1. As per load requirement calculate the voltage and maximum current
limit to be set on Output. Note: V=IxR
2. Disconnect the load from output terminals.
3. For current limit adjustment, turn the current adjustment knob (11)
counter-clockwise to get minimum current output.
4 Short the circuit between the (7) and (5) output terminals by
the accessory leads.
5. Vary the current adjustment knob clockwise until the 1672 current (Red)
displays the required current limit. The C.C. LED will be lighted while
adjusting the current limit. Remove the accessory lead after current
limit adjustment.
6. The voltage will be displayed again and C.V. LED (Green) will be
lighted.
7. Vary the voltage adjustment knob (10) to get the desired output
voltage on the (Green) display.
Depending on Load condition power supply will work either in C.V. or in C.C. mode. The
automatic changeover is indicated by the C.V. / C.C. LED’s.
