Iwatsu SS-250 Current Probe

0 reviews | Model: SS-250

Compare

Current Probe, DC-100MHz, Max. 30Arms/50Apeak

Low noise characteristics for easy milliampere order observation
Wide bandwidth - DC to 100 MHz (SS-250)/DC to 50 MHz (SS-240)
High sensitivity and wide bandwidth implemented through use of thin-film Hall element
Power can be provided directly from the oscilloscope
(Models with on-board power supplies for Iwatsu probes - TS-81000, TS-80600, TS-8500, SS-7840H, SS-7840, SS-7830; models with on-board power supplies for Iwatsu probes, that are no longer available - SS-7825; models with on-board power supply connectors for other probes)
Clamp type, enabling easy measurement without having to disconnect the electrical circuit
Equipped with a function that provides simple protection for excessive input
Can also be used with measuring instruments that do not have a power supply for probes (power can be provided through the optional probe power supply PS-26)
Caution
-1. Use this product in circuits that do not exceed the maximum usable circuit voltage, so as to avoid accidents such as short-circuits and physical injuries.
-2. Do not use this product with bare conductors, so as to avoid accidents such as physical injuries and short-circuits when the leading end of the clamp core is opened.

Applications:

These current probes can be used as-is with oscilloscopes that feature power supply connectors for active probes. Current probes can also be used with oscilloscopes without power supply connectors for active probe, when used in combination with the power supply (PS-26) that is sold separately.
Use a jack plug conversion BNC plug adapter for oscilloscopes for which connection to the SS-240/250 is obstructed due to the input BNC connector being built into the external case (Iwatsu product DS-8710/8706).
When the SS-250 is used with an oscilloscope with a power supply for a probe, if the current being measured is large, the power supply for current probe PS-26 may be required.
With the power supply for current probe PS-26, if the current being measured is large, it may not be possible to use two SS-250 units at the same time.
