Product Description
Rail mounting device, 4 rail units
ETS product family: Physical sensors
Product type: Energy detector
Characteristics
The energy detector has three channels for connecting loads to up to three separate phases with a common neutral conductor. Each channel can measure:
- Voltage (eff.)
- Current (eff.)
- Active power
- Reactive power
Additionally, the active power and reactive power of all channels will be summed up and displayed as three-phase power values along with the mains frequency. According to the parameterisation the measured values will be transmitted on the KNX bus, either cyclically and / or when the value changes. An additional telegram will be transmitted if certain values exceed or fall below a specified limit.
The following meters exist for each channel and for the three-phase values:
- 1 x energy meter total
- 1 x energy meter ¼ h value
- 3 x energy meter n
- 3 x energy intermediate meter n
- Direct measurement (without transformer)
- Transformer measurement (with external 75 A transformer, ratio 75:5, e.g. Phoenix Contact order key 2277611)
