FWZ12-65A Wireless Single-Phase Energy Meter Transmitter
Wireless single-phase energy meter transmitter module FWZ12-65 A
Only skilled electricians may install this electrical equipment otherwise there is the risk of fire or electric shock!
Temperature at mounting location: -20°C up to +50°C.
Storage temperature: -25°C up to +70°C.
Relative humidity: annual average value <75%.
Wireless single-phase energy meter transmitter module, maximum current 65 A.
With internal antenna.
Only 0.5 watt standby loss.
Modular device for DIN-EN 60715 TH35 rail mounting.
1 module = 18 mm wide, 58 mm deep.
This single-phase energy meter measures active energy by means of the current between input and output and transmits the consumption and meter reading over the Eltako wireless network.
Accuracy class B (1%).
Evaluation on the computer with Eltako Wireless Building Visualisation and Control Software GFVS or with energy consumption indicator FEA65D.
GFVS Energy supports up to 100 transmitter modules, GFVS 3.0 up to 250 transmitter modules.
The internal power consumption of max.
0.5 watt active power is neither metered nor indicated.
Like all meters without declaration of conformity (e.g. MID), this meter is not permitted for billing.
- phase conductor with a max. current up to 65 A can be connected.
If the anticipated load exceeds 50%, maintain an air gap of ½ pitch unit to the devices mounted adjacently. If necessary, use spacer DS12. The inrush current is 40 mA.
The consumption is saved to a nonvolatile memory and is immediately available again after a power failure.
Wireless telegrams: A telegram is transmitted within 60 seconds if the power status changes by min. 10 percent. A change in meter reading is transmitted immediately. A full telegram comprising meter reading and power status is transmitted every 10 minutes.
When the power supply is switched on, a teach-in telegram is sent to teach in the associated energy consumption indicator.
If the L input and the L output were inter changed when hooked up, a normal rate (HT)/off-peak (NT) switchover telegram is transmitted to indicate the hook-up error.
