Optical Fiber Isolation System (analog trans.): PH-A360-041-200


Photonics' Optical Fiber Isolation System isolates the signal sensing unit from the waveform detector which observes waveforms of surge impulse.
Calibration of zero level/amplitude level is automatically set and it can be controlled via command from OE converter. The input range of EO converter: }0.1Vmax to }10Vmax is set from OE converter.
The optical fiber is 200ƒΚ‚ core multimode fiber and a set of three optical fibers (analog signal transmission x 1, channel and digital control signal x 2 channels), which can be extended to about 600 meters at maximum, are employed conjointly.
EO unit is operated by the detachable secondary cell and it enables the floating observation of EO unit.
The operating time is approximately 10 hours (with standard cell).
