Features:           1. Dual channel, two circuits of adjustableoutput voltage 0~32V and one circuit of fixed voltage 5V.     2. Master-slave tracking, constant voltageand current, & 8544;, & 8545; circuit can be used for master-slave tracking and used in parallelor in series.     3. Forced ventilation, temperature controlcooling system. When the temperature reaches 65& 8451;, the device dissipatesheat automatically.     4. Display mode: LED digital tube display,can show voltage and current simultaneously.     5. Low ripple, low noise     6. High regulation: 0.01%     7. Output ON/OFF control     8. Constant voltage and constant currentoperation     9. Optional European standard outputterminal     10.
