[FA-665B] Triple regulable DC power supply (2x30V / 5A), aux 5V / 3A

Bench power supply including two 30V/5A variable outputs that may be configured in independent, serial or parallel modes plus a fixed 5 V and 3 A output. It is designed for universities, training centers and the automotive industry.


The FA-665B is a high-precision DC regulated power supply has three ways output. Of which, two ways are adjustable and one way is fixed.

The two adjustable outputs can also be selected for constant voltage or constant current, designed in high stability and performance circuit. In constant voltage state, the output voltage can be arbitrarily adjusted from 0 V on in the nominal range; and in the state of constant current, the output current can be adjustable from 0 A on in the nominal range. The two outputs can be connected in parallel or in series, while the master used for voltage or current adjustment. The maximum output voltage in series is double of independent's, and the maximum output current in parallel is double too.

There are volt and Amp meters (LED) for indicating each of the two outputs with high accuracy.

The one fixed way outputs 5 V voltage. Due to the single chip integrated regulator, this output has good stability and ripple factor, and has reliable overload protection to protect the unit against being damaged whenever overload or short circuit.

The unit features in small size, good performance, novel appearance and etc, it is the ideal power supply unit for science investigation, college, factory, electronic appliance maintenance and etc.
