Zero Current Switching (ZCS) ensures that a relay contact is closed at the zero crossing and opened at the precise moment when zero current flows through it. This has a number of advantages for smart power devices using relay switching techniques. With less potential harm from inrush currents, there is less wear on the relay itself and greater protection for connected switch mode power supplies (SMPS). There is also significantly reduced electromagnetic interference from repeated switching On/Off. Opening a relay contact when the current is zero is important for inductive loads (motors, transformers) but less so for capacitive loads including switch mode power supplies (SMPS) of the type found in computers, servers and IT network peripherals.

Perseus Monitoring
The Perseus Monitoring series is designed for environmental monitoring in the IT, pharmaceutical, food and other manufacturing and process control industries, and includes support for the audit of independent ISO Quality Management Systems (QMS) and other specific professional certifications.
Perseus Energy
The Perseus Energy series is designed to measure energy consumption and savings, and develop methods to improve the efficiency of heating and cooling systems, including the production of independent reports for subsidy and grant schemes.
Perseus Industrial
The Perseus Industrial series is a range products designed for project deployment in a wide range of environments, including engineering applications and is primarily aimed at supporting industry standards. The devices can run as PLCs using customer specific LUA scripts.
Perseus devices are designed to efficiently evaluate and transmit accumulated data to a remote portal, applying logic in order to allow both simple or more complex actions to be taken.
