- -25°C to 71°C operating range
- 1500 V input/output isolation
Description
Sensoray's model 207 PC/104 Isolated Power Supply features a wide input voltage range and up to three isolated outputs rated at +5 VDC at 4 A, +12 VDC at 0.42 A, and -12 VDC at 0.425 A..
Three different terminations are provided for applying input power. One of these is a spring-loaded terminal block that accepts two wires so that input power can be connected directly, without the use of a connector. There are two output terminations for supplying regulated power to external devices; these are typically used for devices such as a cooling fan and RF amplifier (e.g., model 2400-500RF).
