1. 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 So knob 6 should be rotated clockwise to maximum then the two outputs are in series Bv series connection if there is power output proper leads corresponding to output power should be used to short connect the negative terminal of master output with positive terminal of slave output reliabiv Since it is shorted bv a switchinside the unit current will pass on the shorted switch when there is power output This will affect the reliabilitv of the unit 2 2 3 Parallel using of the two adjustable outputs Press in switchs 15 at this time the two output are in parallel adjust voltage adjustment 20 of master output the voltage of two wavs keep same and slave output CC indicator 3 lights on When the two outputs are in parallel the CC adjustment 6 of slave output does not work When used as CC supply simply adjust the CC adjustment 21 of master output at this time output current of both master and slave are controlled by it and are same output current is up to double of independent s maximum current While the two outputs in parallel proper leads corresponding to output power should be used to short reliably the two positive terminal and the Two negative terminals of master slave output separately so as to2. 0 MI2066 FA 665B ADJ USTABLE DC REGULATED POWER SUPPLY FA 665B USER S MANUAL SAFETY NOTES Read the user s manual before using the equipment mainly SAFETY RULES paragraph The symbol A on the equipment means SEE USER S MANUAL In this manual may also appear as a Caution or Warning symbol WARNING AND CAUTION statements may appear in this manual to avoid injury hazard or damage to this product or other property USER S MANUAL VERSION Version Date September 2015 FA 665B USER S MANUAL SAFETY RULES A These instruments fulfill the regulations of CE LVD EN 61010 2001 and CE EMC EN 55022 1998 A1 2000 EN 55024 1998 EN61000 3 2 2000 EN61000 3 3 1995 To ensure safe operation of the equipment and eliminate the danger of serious injury due to short circuit arcing the following safety precautions must be observed Damages resulting from failure to observe these safety precautions are exempt from any legal claims whatever Prior to connection of the equipment to the mains outlet check that the available mains voltage corresponds to the voltage setting of the equipment Connect the mains plug of the equipment only to a mains outlet with earth connection Do not place the equipment on damp or wet surfaces Do not subject the equipment to direct sunlight or extreme temperatures Do not subject the equipment to extreme humidity or dampness Replace a defective fuse onl
