Page 11: Operating Instructions
Operating Instructions Setting the Output Voltage and Output Current As per load requirement, calculate the voltage and maximum current limit to be set on output. Note: V=IR Disconnect the load from output terminals. For current limit adjustment, turn the current adjustment knob counter-clockwise to get minimum current output. -
Page 12: System Configuration
System Configuration Models 1672 and 1673 have two variable outputs, which can work independently, in series tracking mode, or parallel mode with pull and push switch arrangements provided by the master voltage and current control knobs. Users can also connect multiple units in series or parallel mode to increase their voltage or current. -
Page 13: Parallel Tracking Mode
LOAD Figure 5 – Series Tracking Mode Load Connection 5.3.3 Parallel Tracking Mode In this mode, the positive output terminal of the master gets connected internally to the positive output terminal of the slave and the negative output terminal of the master gets connected to the negative output terminal of the slave. -

LOAD Figure 6 – Parallel Tracking Mode Load Connection 5.3.4 Multiple Units in Series Mode For achieving higher voltage, two or more units can be connected in series (Max 240V only). The output voltage of the system will be the sum of all units. Set the power supplies connected in series operation under series tracking mode as described in Series Tracking mode and adjust to the same output. -
