Current transducers are used in many industrial applications to monitor or record current intensity. A range of features lets you customize these things for different measurements. A current transducer can, for example, measure very low currents, while another is designed for measuring large currents.
HiLetgo Digital Current Transducer
Using the HiLetgo Digital Current Transducer, you can measure the current flowing through an electrical circuit. It has a working voltage of 80-260VAC and a working frequency of 50/60Hz. The accuracy of measurement is 1%. Power consumption is 0.2W. Measurement speed is two times/s. Data storage when power off. Enable blue backlight on / off manually.
HiLetgo Digital Current Transducer can only measure AC circuits’ active power (real power). It cannot show apparent power or other values. Additionally, it features an overload alarm function to help prevent device damage or injury to people in case of electrical failure.
To install, connect the CT clamp around one phase wire and the voltage reading wires to lines 1 and 2 of your circuit. The backlight on the device can be turned on or off as needed, though it will automatically turn itself off after some time to conserve energy.

For accurate readings, the AC input should be in pure sine waveform. Many power sources are already pure sine wave, but if you are using an AC-DC converter, please make sure that the output from your inverter also meets this standard. You should not use this module outdoors and should not exceed its maximum rated power when wiring it. (It is essential to maintain proper wiring to prevent damage to the device if the applied load exceeds the rated power.)
CrocSee Digital Current Transducer
Using the CrocSee Digital Current Transducer, you can measure the current in an electrical circuit. It has a working voltage of 80-260VAC and a rated power of 100A/22000W. The operating frequency range is 45/65Hz, and it can operate within a temperature range of 14℉~140℉. This transducer has 1% measurement accuracy.
The CrocSee Digital Current Transducer is a device used to measure electrical parameters such as voltage, current, active power, energy, frequency, and power factor. In addition, it has an overload alarm that causes the backlight and power numbers to flash when power exceeds the preset value. There is a button on display for resetting energy data. Additionally, the transducer has a switchable backlight and a large, legible LCD screen. Finally, it can store data when no electricity is present, so you can still see your power consumption even if it is out.

You shouldn’t measure the AC power converted from DC, such as that from a DC-AC inverter; however, if it generates a pure sine waveform, which more closely resembles the type of electric power typically supplied by municipalities, it’s okay to use.
It shouldn’t be exposed to outdoor conditions; it’s for indoor use only. Furthermore, the applied load on the measured circuit shouldn’t exceed the device’s rated power. Reversing the wiring order between lines could damage the transducer and the attached equipment.
CrocSee Miniature Current Switch – CS-TS0
Using the CrocSee Miniature Current Switch, you can measure the current flowing through a circuit. It has an enclosure with dimensions of 88 x 25 x 50mm and mounting holes spaced 76mm on the base. The voltage range for the switch is 120-240VAC, with a rated load capacity of 2.5 A.
This switch’s contact type is normally open, which means that it’ll stay open until it senses a current higher than the threshold set point rating, then it’ll close.
It doesn’t operate well in environments where the relative humidity exceeds 95% non-condensing relative humidity, as moisture may interfere with its function. Its operating temperature range is from -20°C to 45°C (-4°F to 113°F). This model’s hysteresis (differential between ON and OFF switching thresholds) should not exceed 1%.
CrocSee AC Current Switch senses current draw between 1 and 50 amps and closes a set of contacts while AC passes through it. It allows for automatic control of systems or machines to prevent damage from excessive currents.
Conclusion
The three products are all current transducers used to measure the amount of current flowing through an electrical circuit. The first two, HiLetgo Digital Current Transducer and CrocSee Digital Current Transducer, can both be used to measure voltage, current, active power, energy frequency, and power factor. They also have similar accuracy levels (1%). If a preset value is exceeded, both devices will flash the backlight and power numbers, and they can store data without electricity.
The main difference between these two devices is that the HiLetgo has a blue backlight that can be turned on or off manually. In contrast, the CrocSee’s display screen will automatically turn off after some time to avoid wasting energy. Also, the Crosee comes with mounting holes making it easier to install than its competitor.
However, overall, they provide more or less the same features at slightly different price points, with one having slight advantages over another in certain areas.
