Double Ammeter

Designed to measure AC/DC current and Volt, these meters indicate true r.m.s. values and are substantially independent of system waveform.

Specification: 1A 3A 7.5A 10A 20A 30A 50A 60A 75A 100A. For 10A -10KA, use external 75mV, 65mV or 45mV shunt.
Notes: For 50A 60A 75A 100A meters, when these meters directly connected to circuit, their accuracy is class 2.5
Case: Non-combustile ABS plastic material is used for making SF series'external case,and PPO plastic material is used for SF series's base; while Non-combustible PC plastic material is used for making SFT series'external case and base. Both of which will not suffer deformity under long-term use at 70°C and 120°C respectively.
Changeable scale: Scale can be changed without opening meter, convenient to use, effective dust proof. Under the same input signal, scale-change can be conducted without loss of accuracy or damaging the meter.
Mounting: SF series is flush mounting with bracket.
