AXIOMET AX-3003L-3 Расширенная инструкция онлайн [2/5] 528017

This series includes 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 to 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.
