Relay for energy flow EFR4001IP by Ziehl
The EFR4001IP power flow relay monitors the flow of power between the consumer and the public power at the grid connection point. The ERF4001IP now allows an increase of two-thirds of the generation power than the grid connection allows, when the overbuilt power is consumed and not supplied to the public power grid. Monitoring ensures the stability of the system.
Product advantages
- Convenient operation via built-in web server or LCD plain text display
- Control of heat pumps (SG-ready)
- Partial or complete shutdown of generators when the permissible feed-in power is exceeded.
- Connection of up to 3 consumers
