Thông tin sản phẩm

- Relays for energy flow EFR3000 monitor the current flow between public power grid and generating plant / consumer. When the own power plant generates more power than actually is consumed it often is more economical to consume the excess energy self. This is especially reasonable when the difference is high between the price you pay to the grid provider and the price the provider pays for fed in energy.
- Shift own consumption into times with high generation of energy
- Switch on consumers when you have overflow of energy
- Increase the share of consumed own energy
- intelligent control of consumers
- Measuring of active power
- Measuring inputs isolated from electronics
- Colored LCD display
- Intuitive handling with joystick
- 3 inputs for customary current transformers with secondary 1 or 5 A. Ratio programmable
- 3 relay outputs, 2 kW directly, higher loads with  contactors
- 2 digital inputs Y1/Y2 for control signals
- Analog output for stepless regulation of a consumer
- Measuring transducer with analog output 0/4-20 mA for power L1, L2, L3 or L1+L2+L3. Measuring range can be scaled
- Micro-USB port for configuration and update
- Interface RS 485 (Modbus RTU)
- Housing 140 mm wide
- Zero Export Device. Switch off within <500 ms at inadmissible feed in that is contrary to contract
