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 t he 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.
