CG FL21 DC Current Shunt Resistor — 600A, 60mV Key benefits Accurate, lowvoltage way to measure DC currents. Delivers a small millivolt signal proportional to current for safe, reliable measurement with standard meters and data loggers. Solves the problem of directly measuring large DC currents without expensive clamp meters or intrusive instrumentation by providing a predictable voltage drop (mV) at full rated current. Flexible series offering: available in multiple current ratings and mV output options so you can choose the shunt that matches your meter input and system range. What this product does Converts DC current into a precise millivolt output (60mV at the rated 600A for this unit) so you can monitor current with voltmeters, analog/digital ammeters that accept shunt inputs, or data acquisition systems. Key specifications and attributes Model: CG FL21 series This unit: 600A, 60mV (produces 60 millivolts at 600 amps) Available ratings in the series: 250A, 300A, 400A, 500A, 600A, 800A, 1000A, 1200A, 1500A Available nominal outputs: 75mV, 60mV, 100mV (depending on model) Functionality: DC current shunt resistor for measurement purposes Compatibility: Designed for use with meters, panel instruments, data loggers and control systems that accept lowmV shunt inputs Performance note: Linear, proportional millivolt output at rated current (e.g., 60mV at 600A equals 0.1 mV per amp) How it helps in practice Easy integration: connect the shunt in series with the load and measure the small voltage across the shunt with your instrument. The mV output scales directly to current according to the rated mV at full current. Simplified scaling: for this 600A/60mV unit, 1 amp = 0.1 mV (60mV / 600A). Read the mV on your meter and multiply by 10 to get amps, or configure your meter/data logger to use the 60mV fullscale reference. Typical applications Solar and battery systems: Monitor battery charge/discharge currents and inverter/charger performance in offgrid and hybrid systems. Power supply and equipment testing: Measure DC currents in laboratory or production environments where accurate, repeatable readings are required. Industrial control and energy monitoring: Integrate into panels and control systems for motor current monitoring, load management, and energy metering. Why choose the CG FL21 series Wide range of current ratings (250A–1500A) and mV output options (60/75/100mV) let you match the shunt to your instrumentation and measurement range without modifying your equipment. Straightforward electrical interface: lowvoltage output compatible with most common meters and data acquisition inputs for easy installation and system integration. This specific model (600A, 60mV) provides a convenient 0.1 mV per amp scaling for precise measurement of midto DC currents. Ordering and selection tips Confirm the meter or data logger input accepts the chosen mV fullscale output (60mV, 75mV, or 100mV). Pick the shunt rated at or above the maximum current expected in your application to avoid overload. Specify model CG FL21 and the desired rating (for example: CG FL21 600A 60mV) when ordering. Includes CG FL21 shunt resistor in the specified rating and mV output (600A, 60mV for this unit). Follow standard installation and safety procedures when wiring and measuring currents.
