Applications

Closed loop (compensated) voltage

transducer using the Hall effect

Insulated plastic case recognized

according to UL 94-V0.

Railway equipment.

For voltage measurements, a current

proportional to the measured voltage

must be passed through an external

resistor R

user and installed in series with the

primary circuit of the transducer.

Excellent accuracy

Very good linearity

Low thermal drift

Low response time

High bandwidth

High immunity to external

interference

Low disturbance in common mode.

AC variable speed drives and servo

motor drives

Static converters for DC motor drives

Battery supplied applications

Uninterruptible Power Supplies

(UPS)

Power supplies for welding

applications.
