The RET-10 block allows high-precision scaling of one of the output current channels of RETOM-51(61) with the factors 10, 5 and 0,1, thus providing for the possiblilty of testing with the wider range of currents and loads.

From the user's standpoint, RET-10 block allows to widen the technical application of RETOM-51(61) considerably, namely:

  • to bring the maximal output current to 200 A,
  • to lower the minimal output current to 1 mA,
  • to issue current in the range of 2 A at high-impedance loads of up to 65 Ohm.

The current converter block RET-10 is made on the basis of magnetic core from nanocristallic alloy with rare-earth components.
