Fiber Optic Isolated Voltage Probe. ISOVP
The ISOVP isolated voltage probe allows the safe and accurate measurement of floating voltages in power electronic modules or electronics. Although it is best suited for medium voltage equipment due to the isolation provided, the high common mode and EMI rejection make it a perfect choice for general low voltage measurements. The 25V input voltage range with the supplied x10 attenuator is ideal to measure gate voltage in various semiconductor switching devices and study potential problems and improvements. Also input capacitance has been kept to a minimum as this is what really hurts most high-frequency measurements, causing loading of high and medium impedance signal sources and signal degradation.
A calibrate function brings the zero automatically to its position and calibrates the gain of the probe, all this without the need to disconnect the input signal as compared to other probes. A remote standby function allows to safely reduce the power consumption and extend battery life of both probe head and receiver without accessing potentially hazardous areas. The output signal is provided via a BNC connector which allows the use of any 50Ohm input terminated scope.
The probe head is small enough to be used inside cabinets and small modules. It also features a camera mount type tripod thread that allows easy placement and clearances from the probe to ground to be maintained.
