– Typical Applications
DC current measurement in power supplies, battery charging systems, load banks, and industrial control circuits. Ideal for data acquisition systems requiring galvanic isolation and direct analog signal conditioning.
– Compatibility & Integration
The 50mV output directly interfaces with standard analog instrumentation inputs, multimeters, and data loggers. Continuous operation should maintain current below 6.67A (two-thirds rated current) per AIEEE standards to optimize component longevity. Screw terminal design accommodates AWG 4 to 6 cable gauges typical in industrial power circuits.
