Key Specifications & Feature
Double Type Moving Iron Ammeters
Feature: W/O cover on the movement(C), With cover on the movement(F)[the former is default]
Model: 90¡ã SF-144-3 SF-96-3 SF-72-3 SF-48-3
> Measuring the alternative current or voltage with frequency ranging from 15Hz to 100Hz,these meters indicate true RMS values and are substantially independent of system waveform.The nominal mark is T. Accuracy: Class 1.5
Specification: 0.1A 0.5A 1A 7.5A 10A 15A 20A 25A 30A 40A 50A 60A 75A 100A, for 10A-10KA use external current transformer with secondary current 5A
Notes: For 60A, 75A, 100A meters, when these meters directly connected to circuit, their accuracy is class 2.5
CP/KLY-T48A is class 2.5 for 20-60A
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¡æ and 120¡æ respectively. The highest enclosure code is IP54.
Changeable scale: Scale can be changed without opening meter, convenient to use, dust proof. Under the same secondary current, scale-change can be conducted without loss of accuracy or damaging the meter (48¡Á48 model must have identical scale class range).
Mounting: SF series is Flush mounting with bracket.
