Sensoray has developed the Model 207 PC/104 Isolated Power Supply featuring input voltage of 9-36 VDC nominal, output voltages and currents of +5 VDC at 4 A maximum rating, +12 VDC at 0.42 A maximum rating, -12 VDC at 0.425 A maximum rating. The 207 has -25°C to 71°C operating range and 1500 V maximum input/output isolation.
The 207 has three different terminations for applying input power. One of these is a spring-loaded terminal block that accepts two wires without the use of a connector. There are two output terminations for supplying regulated power to external devices such as a cooling fan and RF amplifier 2400-500RF.
