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.
