Single Phase EC-2VA AC Voltage Current Logger

The EC-2VA AC Voltage Current Data Logger is specifically designed to monitor one voltage channel and one current. It allows you to monitor the main voltage supply and the load current, enabling staff to determine whether a voltage problem is load related or not.

The Electrocorder range is designed to allow electrical distribution companies to cost effectively monitor single and three phase supplies. Our products allow voltage problems to be highlighted quickly for further investigation. The EC-2VA is designed to allow engineering staff to monitor single phase voltage and current.

The voltage and current levels are stored with dates and times. With the backup battery, the Electrocorder can continue to record for a year. On the logger, recording is signified by a flashing green light. A red light advises users that the unit has completed recording.
