• Notes

• The Precise Power Lab 713 combines a variable high current low voltage power supply with an isolation transfomer that can be used independently or can be switch-connected as series-aiding or bucking for a variable isolated supply up to 3 amps AC for 90-140 volts, which can in turn be selected as rectified and filtered from 110-180 VDC at 75 mA continuous. 

  Variable low voltage at high current is available as AC from 0-24 volts up to 20 amperes or DC from 0-15 or 0-30 Volts at 10 amps continuous. 

  The high current low voltage variable AC can also be switched to boost or buck line voltage directly from 90-140 VAC up to 10 amps continous but without isolation.  The 713 was available as either 713K (kit version) at $62.95 or 713W (wired version) at $79.95.  The 713 isolation transformer was rated at 300 watts.  A model 711 was also available at lower cost but limited in isolation transformer output to 100 watts.  See the January 1957 ad in Popular Electronics (uploaded) for further detail.
