2.  Control Table   SX-20KVA (1 set)
Features:
   Information including voltage, current, time, status, prompt notice and etc could be read on large LCD screen.
   Fully English interface, easy to operate.
   All the functions are settable by touching key, safe and reliable.
   Digital calibrating, suitable for onsite testing.
   High voltage icon flash indicating.
   Auto displaying test result (pass or fail), and recording the test object over current and voltage value of flashing or breaking down.
   Different alarm sounds if test is passed or failed.
   Could be paused arbitrarily under auto controlling mode.
   Withstand voltage time is settable from 0 to 9999 seconds.
   Auto timing: Under auto controlling mode, when the voltage is auto rising to the setting value, the unit starts to auto timing. After timing is up, to display test result, and back to zero start automatically.
   Manual timing: Under manual control mode, timer could be started by manual. After withstand voltage timing is up, unit to back to zero start automatically.
   Manual control mode: to increase/decrease the voltage by button control, unit to react the high/low limitation automatically, over-voltage, over-current protecting functions. To control the test process manually.  
   Fixed primary current overload, factory set to 120% of variable transformer rated primary current.
  Adjustable secondary current overload, variable from 10-110% of secondary current rating.
  Stop/emergency button, could restart manually.
  The voltage could be return to 0 V within few seconds after release safe button.
  To control rising rate intelligently, when the voltage is closing to setting value,  rising speed could be auto slowdown.
 Switch selectable output rate of rise, with fixed speeds of 750V/205kV/5kV/7.5kV per second.
   Over-current, flash, breakdown protection.
   0-10V DC analog feedbacks for output voltage and current.
   High stability and reliability.
   Communication function, to realize remote control and data monitor. (optional)
   Build-in printer (optional)
