This series include two-way and three-way DC regulated power supply.
Three-way have high accuracy output of which two way are adjustable and one
way is fixed.
The two adjustable outputs can be selected for constant voltage (C.V.) or constant
current (C.C.), designed in high stability and performance circuit. In constant
voltage operation mode the output voltage can be arbitrarily adjusted from 0V on
in the nominal range. In constant current operation mode, the output current can
be adjusted from 0A on in the nominal range.
The two outputs can be connected in parallel or in series, while the master adjust
controls the voltage and current setting. The fixed output voltage is 5V. This
output features good stability and low ripple along with overload (e.g. short circuit)
protection.
The unit features small size and excellent performance combined with an elegant
design, being ideal for research university industry and appliance maintenance
laboratories.

2. Operation
2.1 Controls and description of front-panel
(1) Meter or (LED): indicates master output voltage and current value.
(4) Meter or (LED): indicates slave output voltage and current value.
(5) Slave constant voltage adjustment: adjust slave output voltage value.
(6) Slave constant current adjustment: adjust slave output current value. (adjust
the current-limiting protection point).
(7) Power switch: It is set to “ON” state (the switch is pressed in), the unit is
switched on, at this time the constant voltage (C.V.) or constant current (C.C.)
indicator is on, otherwise, the unit is in “OFF” state (the switch is sprung out).
(8) Slave constant current state or two-way parallel state indicator: When slave
output is in constant current state or the two adjustable is in parallel, this
indicator is on.
(9) Slave constant voltage indicator: When slave output is in constant voltage
state, this indicator is on.
