Transducers
T-51HSS
T-51/T-101 Series
Current Transducers (Saturated Power) [Insulated]
Suited for motor circuits, heater circuits and other circuits in which an overcurrent flows during
startup.
When combined with a needle indicator, an indicator with the scale expanded three-fold is realized.

The load resistance connected to T-51KSS is fixed. In the case of current output, please specify a
resistance value no more than that shown in the table above; specify a resistance value no less than that
shown in the table above in the case of voltage output.
Models with 2- to 5-times expanded saturated power can also be manufactured.
Error may occur when the input waveform is distorted.
For example, when the third harmonic content is 15%, the error is approx. ±5% for T-51KSS and ±2% for
T-51HSS.
The tolerance of the maximum saturated power is within ±10% (% in respect to saturated power value).
