15Hz - 100Hz Square Type Moving Iron AC Voltmeters, Digital Panel Meters

15Hz - 100Hz Square Type Moving Iron AC Voltmeters, Digital Panel Meters

Description:

Feature: W/O cover on the movement(C), With cover on the movement(F)[the former is default]
Model: 90° SF-144-3 SF-96-3 SF-72-3 SF-48-3
> Measuring the alternative 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.(br)  

Accuracy: Class1.5
Specification: 30V 50V 75V 100V 120V 150V 200V 250V 450 500V 600V For 450-450KV, meters can use potential transformer with secondary voltage 100V or 110V
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 and 120 respectively.
Mounting: SF series is flush mounting with bracket
