PPS-4A Astron DC Power Supply

Used
The PPS-4A is a 65 Watt DC Power Supply from Astron. Supplies DC Voltage and Current to test, design, and troubleshoot electric and electronic circuits. Applications include Burn In, QA, ATE, Research, Design, and Education to name a few.

Additional Features:

  • Output Voltage: 0-16V DC continuously variable with coarse and fine controls
  • Load Current: 0-4 amps max., continuously variable with coarse and fine controls
  • Constant Voltage Mode Regulation: Less than ± 0.02% +2mV for ± 10% change in line voltage 
  • Load: Less than ± 0.02% +2mV for load change from zero to full load
  • Load Ripple and Noise: Less than 1mVrms max (20 Hz - 20 MHz)
  • Constant Current Regulation Line: Less than ± 0.5% +250uA for ± 10% change in line voltage
  • Load: Less than ± 0.05% +250uA  for change in output voltage from 0 volts to maximum output voltage

The PPS-4A preset regulated DC power supply has a unique feature to preset the voltage and current without actually loading the unit. It is a well regulated constant voltage voltage/constant current supply which delivers 0-16V at 0-4 amps and can be adjusted continuously throughout the output range. The front panel current control cab be used to establish the output current linit (overload) or short circuit). When the supply is used as a constant voltage source the voltage controls can be used to limit the output voltage. When the unit is used as a constant current source, current controls can be used to limit the output current. The unit will automatically cross over from constant voltage to current mode and visa-versa if the output current or voltage exceeds these preset limits.
