SH Series Shunt Resistors

Precision metal clad resistors are distinguished by high load capacity

Ohmite's SH SeriesOhmite's SH series of shunt resistors offers a range of capabilities from 100 to 300 amps in a sturdy metal-clad housing. Standard part numbers all offer 0.5 percent tolerance and convenient 400 mm long insulated wire sense leads for convenient and accurate current monitoring. The manganin plate housed inside the SH devices forms the resistive element.

For safety, the SH series is supplied in a metal clad housing, making it more suitable for end-product use. The SH is ideally suited for use in renewable energy applications such as battery banks, wind turbines, and solar panels.

Precision metal clad resistors designed in a four-terminal technique are distinguished by high-load capacity as well as excellent accuracy. Isolated voltage and current connectors make them suitable for very precise current measurements. The simple four port Kelvin design ensures easy installation on large-current bus bars. Units have a low inductance and heavy copper terminals. Applications include: battery testing, current detection in precise power sources, constant current sources, industrial power conversion circuits, HEVs, fuel cells, and constant electronic loads.
