Product Description:
space
space MAR & MVR series, are true rms,meters, they are able to measure a distorted sinusoidal wave with harmonics or periodical of non-sinusoidal signal. These meters have a very low burden of 0.25 VA. Their internal shunt provides for direct connection to 1A or 5A CT’s (current transformers) and up to 700 VAC
