Ultra Extremely fast voltage amp feedback and control system

S&R Engineering has developed ultra extremely fast voltage and amp feedback control system.

This S&R Engineering "Nano Feedback Control System" are achievement to controlled speed by nano second.

Extremely fast high power forward transfer admittance.

I-VAC has been optimized for very low forward voltage drop, with moderate leakage.

The S&R Engineering technology allows for reliable operation from -55°C to up to 140°C unit temperature.

possible to set Voltage every 0.01voltage , from 12.5v to 60v

Spec of Automotive Wire Harness (AWG12)

Note: Ampacities based on single conductor in free air, 30°C (86°F) or 40°C (104°F)

ambient temperature as specified, 105°C (221°F) conductor temperature, per table

310-17 of the NEC (adjusted for 105°C). Free air ratings assume a one cable diameter

spacing between adjacent conductors.
