Features and Applications

特長用途
小型軽量のパワーエレクトロニクス用、計装用電流シャント抵抗。
0.25％の許容差、長期安定性、低熱電力、優れた抵抗温度係数の優れた性能を有する。
電流端子、電圧端子ともねじが付属していて、電流ブスバーへの取り付け、電流計への接続が簡単。
このシリーズは米国計測研究所の標準とトレーサビリティを保証。
精密電源装置、電力変換装置、電流計測、電力量測定器など。

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 to ampere-meter through flexible
wires.
All of shunts are calibrated on equipment with current
certifications traceable to US-N.I.S.TFor 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
degrees
Ctheresistance may drift.
The temperature of theshunt is measured on
the resistance strips.
