RoHSSHUNT - NIKKOHM

LIGHTWEIGHT PRECISIONCURRENT SHUNT RESISTORSNSLA10, NSLA20, NSLA30
NSLA50, NSLA75, NSLA80
NSLA85, NSLA100, NSLA150
Features and Applications
Lightweight large current shunt resistors for ampere-meters, designed for power electric equipment.
Excellent long-term stability, low emf and low TCR.
Easy current measurement is performed by attaching to current bus or wires and connecting toampere-meter through flexible wires.
All of shunts are calibrated on equipment with current certifications traceable to US-N.I.S.T
For high precision power supply, power converters, and current measurement instruments.

Note
The resistance willremain within 0.25% if
the shunt is operated
between 20 and 90
degrees C.
If thetemperature of theshuntexceeds
90
degreesC
theresistance may drift.
The temperature of theshunt is measured on
the resistance strips.
