FA-665B 1 INTRODUCTION Description The model FA-665B 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. -

2 OPERATION Control and description of front pannel Figure 1. Front panel description. Volt display: indicating slave output voltage. Amp display: indicating slave output current. Slave constant-current indicator or two-ways parallel state indication: the LED illuminates when the slave output is in current- regulated state or the two adjustable outputs is in parallel. - Page 8 Case ground: connecting the case to ground. Slave output terminal (+): connecting the positive terminal of load. Master output terminal (-): connecting the negative terminal of load. Case ground: connecting the case to ground. Master output terminal (+): connecting the positive terminal of load. Control switch: for selecting the two adjustable outputs independent, series, parallel.

Page 9: Operating Method
Operating method 2.2.1 Independence use of two adjustable output Set switchs (15) to spring out position. When the adjustable output is used as CV output, first should rotate clockwise the CC adjustment (6) and (21) to maximum, then turn on power switch (18), adjust CV adjustment (5) and (20) till output voltage reach required voltage value. -
Page 10: Parallel Using Of The Two Adjustable Outputs
When the two outputs are in series, the voltage is controlled by master output, but current adjustment of two outputs is still independent. Therefore, attention should be paid to the position of the CC adjustment (6). For example, knob (6) is at the position of counterclockwise to end or current of slave output excesses current-limiting protection point, at this time, the voltage of slave output will not track the voltage of master. - Page 11 CAUTION: This unit has excellent protection function, 5 V output has reliable protection for current-limit and short. The two adjustable outputs have current-limit protection. As there is controlling circuit for regulating transistor's power loss in the circuit, when short-circuit occurs, the power loss on large power transistors is not very high, it can't cause any damage to the unit.
