The AC / DC sensitive residual current monitoring module is suitable for fault current moni­toring in transformerless photovoltaic inverters where direct and / or alterna­ting fault currents are likely to occur the value of which is constantly greater than zero.

• AC / DC sensitive residual current monitoring module
• r.m.s. value measurement (AC+DC)
• Frequency range 0…500 Hz
• CT connection monitoring
