Fl-2 10A 20A 30A 50A 100A DC ammeter 75MV shunt Purpose: fixed constant value shunt is a suitable for measuring dc current under 10 ka direct effects on analog display instrument and used to enlarge the range of dc current measurement with shunt, or can be used as a current in the circuit in sequence sampling standard resistor, the voltage can be used as a measurement of a current sampling the analog signal. Main technical parameters 1, accuracy grade: 2 ~ 4000A;0.5 level: 5000 ~ 10000A;Level 1. 2, environmental conditions: -40 ~ +60℃, relative temperature ≤95%(35℃). 3, overload performance: rated current 120%, 2 hours. 4, voltage drop: 75mV 5. Heating under load: after the temperature rise tends to be stable, the rated current is less than 50A and does not exceed 80℃; The rated current is above 50A and does not exceed 120℃. |
