  • Cold Start Peak Inrush Current: < 10Apk cold and hot start for < 16ms
  • Power Factor: >.98 at full load. Meets CE requirement (EN61000-3-2)


  • Maximum Total Output Power: 150 Watts
  • Output Voltage: 5Vdc*            
  • Maximum Continuous Load: 30A
  • Minimum Load: 0.0A150 watt single output ac to dc power supply
  • Maximum Ripple: 50mV pk-pk
  • Efficiency: 75% Minimum.
  • Set Point Accuracy: Outputs shall be initially set to ± 2.0% of nominal output voltage.
  • Load Regulation: ±5.0% maximum for minimum to maximum load.
  • Line Regulation: ± 2.0% maximum over the entire AC input range
  • Temp Coefficient: ± 0.02%/degree C


  • Input Surge Voltage: Input transient suppression circuitry to protect power supply from voltage spikes.
  • Input Protection: Internal slow blow fuse.
  • Over Current Protection: Output is protected for overload conditions exceeding 110-115%. Auto-recovery after removal of overload condition. 
  • Short Circuit Protection: The power supply is protected from short circuit conditions and will recover automatically after short circuit condition is removed.
  • Overtemperature Protection: The power supply to shut down during over temperature condition.
  • Circuitry and automatic recovery when temperature returns to normal.
  • Overvoltage Protection: 125% ±5% of nominal. OVP shuts down the unit. AC input line is removed for 5 seconds and then reapplied to turn unit on. OVP sensing is done ahead of the isolation diode.

Safety Agencies and EMI
  • EMI Requirement: Pass FCC Part 15 Subject J class B, CISPR 22 class B.
  • Safety Regulation: Designed to meet UL1950, CSA C22.2 No. 950-95, EN60950.
  • Leakage Current: The AC leakage current shall not exceed 3.5mA when the power supply is connected to a supply voltage equal to the upper limit of the rate voltage range.
  • HI-POT: The power supply shall withstand for 3 Sec without breakdown the application of a 1500 VAC supply voltage applied between both input line and chassis (10mA DC cut off current). Isolating transformers shall withstand 3000VAC


  • Internal Isolation Diodes: Built in isolation diodes in the positive output line to prevent a failed power supply from affecting the bus.
  • AC Power Fail: Upon loss of AC line, signal goes from low to high before loss of output regulation.
  • DC Good Signal: Provides output logic high signal when DC output is present. When the DC output is not present the output of this option will drop to logic ground. LED on indicates output good.
  • Logic Inhibit: Less than 0.5 volts will inhibit the supply. Two volts or more or an open circuit will enable the supply. Logic inhibit return should be connected to negative output.
