Unique-Bargains 50A 75mV DC Shunt Resistor

SKU CH-P4JR-XMWNN

A 50A 75mV DC shunt resistor extends ammeter range with 0.5 class accuracy

  • Product typeHI - Electrical & Industrial Wire
  • 5 class accuracy ensures precise current readings
  • 50 A capacity handles high-current DC circuits
  • 75 mV voltage drop minimises power loss
  • 12 x 2.5 x 1.5 cm footprint fits tight enclosures
  • 59 g lightweight design simplifies panel mounting

Application

This Unique-Bargains DC shunt resistor extends the measuring range of an ammeter up to 50A with a 75mV voltage drop. It is built from metal and plastic in a black and silver-tone housing measuring 12 x 2.5 x 1.5cm and weighing 59g. The unit ships as a single component ready for panel or bus-bar mounting.

Suitability

It suits technicians and hobbyists who need to add high-current DC measurement to an existing analog or digital meter movement. Buyers who require an isolated sensor output, a different current rating, or a calibrated certificate traceable to a standards lab should look at other instruments.

Deciding spec

The 0.5 Class accuracy rating defines the measurement uncertainty you can expect from the shunt. If your application demands tighter tolerance than 0.5 percent of full scale, this part will not meet the requirement.

Questions about this item

What does the 75 mV drop tell me about wiring this shunt into my ammeter?

At 50 A the shunt produces a 75 mV signal, so the meter only needs to read millivolts and the wiring sees minimal loss.

How does the 0.5 class accuracy affect real-world current readings?

The 0.5 class rating means the measured current will stay within ±0.5 % of the true value across the operating range.

Will the 12 cm by 2.5 cm body fit inside a standard DIN-rail enclosure?

The shunt measures 12 cm long, 2.5 cm wide and 1.5 cm high, so check your enclosure’s internal clearance against those dimensions.
