PC/104+, stackable, power supply, PSU, Model 209, SENSORAYPC/104+ stackable high-efficiency power supply


  • Input voltage of 12-24 VDC nominal (8-30V max)
  • Outputs:+5 VDC at 5 A, +12 VDC at 0.5 A, -12 VDC at 0.5 A
  • -25°C to 50°C operating range
  • No active cooling needed

SENSORAY's Model 209 PC/104 Power Supply accepts any input voltage in the range 12-24 VDC and produces regulated outputs of +5 VDC at up to 5 A, +12 VDC at up to 0.5 A, and -12 VDC at up to 0.5 A. The unit has a -25 to 50 °C operating range.


Two different terminations are provided for input power: a 2 mm power jack and a terminal block. Also, two output terminations are provided for supplying regulated output power to external devices such as a cooling fan and RF amplifier 2400-500RF.

Total output powert 37W maximum with forced external cooling
Efficiency > 90% overall input voltage range
Output voltages and currents +5 VDC at 5 A maximum rating
+12 VDC at 0.5 A maximum rating
-12 VDC at 0.5 A maximum rating
Output accuracy ±0.1 V for 5 V output
±0.24 V for +12 V output
±0.24 V for - 12 V output
Temperature range -25°C to 50°C operating range
Output ripple Pk - Pk 100 mV on 5 V  | 100 mV on 12 V
Line regulation (full input voltage rating) ±0.05 V for 5 V output
±0.12 V for +12 V output
±0.12 V for -12 V output
Load regulation (full load swing) ±0.025 V for +5 V output, ±0.12 V for + 12 V output, ±0.12 V for -12 V output
Reverse input polarity protection Unit will restart  when correct input polarity is established.
Short circuit protection Unit will turn off when a short circuit is detected. Power cycling the unit forces the power supply to start after a short circuit event.
Load damp protection Unit is protected against load dump transients
