🖹 Description
SA60-50-0,5 Electric meter
RESISTANCE SHUNT 50A 60mV , 0.5 CLASS
Current Shunt Resistor – ENTES SA60-50 (50A / 60mV)
This is a current shunt resistor, specifically the SA60-50 manufactured by ENTES. It is a precision measurement device used in electrical systems to measure current by converting it into a small, proportional voltage.
What it is
The SA60-50 is a low-resistance shunt designed for accurate current measurement in DC and high-current applications. Instead of measuring current directly, it creates a controlled voltage drop (in millivolts), which can be read by meters, PLC analog inputs, or monitoring systems.
This method is widely used in industrial automation and energy monitoring due to its reliability and simplicity.
Key specifications
- Rated current: 50 A
• Output voltage: 60 mV at full scale
• Type: Precision shunt resistor
This means when 50 amps pass through the shunt, it produces exactly 60 millivolts.
Key difference from other models
| Model | Current Range | Output |
| SA60-50 (this) | 0–50 A | 60 mV |
| SA60-100 | 0–100 A | 60 mV |
Same output voltage, different current range = different sensitivity.
- Lower current rating → higher sensitivity
• Higher current rating → lower sensitivity but higher capacity
How it works
- Installed in series with the electrical load
• All current flows through the shunt
• A small voltage drop appears across its terminals
• A measuring device reads the millivolt signal and calculates the current
This allows safe and indirect current measurement.
Where it’s used
The SA60-50 is commonly used in:
• DC power systems
• Battery monitoring systems
• Energy measurement panels
• Industrial automation and control systems
• Power supplies and charging systems
Advantages
- Good balance between range and sensitivity
• Accurate measurement for medium current loads
• Simple and robust design
• Easy integration with measurement instruments
• Cost-effective solution
Practical selection tip
- Use 30A shunt → for small loads (higher precision)
• Use 50A shunt → for medium loads (balanced performance)
• Use 100A shunt → for high loads (prevents overheating)
Choosing the correct shunt ensures both accuracy and safety.
Simple explanation
In simple terms, this is a “sensor bar” that measures current by converting it into a small voltage. This version is designed for medium current applications (up to 50A), offering a good balance between measurement accuracy and load capacity.
