Single-phase energy meter
WSZ15DE-32A without MID
Only skilled electricians may install this
electrical equipment otherwise there is
the risk of re or electric shock!
Temperature at mounting location:
-20°C up to +55°C.
Storage temperature: -25°C up to +70°C.
Relative humidity:
annual average value <75%.
Maximum current 32 A. Standby loss 0.4 watt
only.
Modular device for DIN-EN 60715 TH35 rail
mounting. 1 module = 18mm wide and 58mm
deep.
Accuracy class B (1%). With S0 interface.
This single-phase energy meter measures
active energy by means of the current between
input and output. The internal power consumption of 0.4 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.
Every 30 seconds, the display switches for
5 seconds from the accumulated active energy
in kWh to the momentary consumption in
watts.
1 phase conductor with a max. current up to
32 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 20 mA.
The display can only be read when the power
supply is on. However, the consumption is
saved to a non-volatile memory and is displayed immediately after power restoration.
Two N terminals for secure cross wiring of
several counters.
The digital display has 7 digits. Two decimal
places are indicated up to 99999.99 kWh.
Above 100000.0 kWh there is only one decimal
place.
Power consumption is shown by a bar ashing
at a rate of 1000 times per kWh.
Error message
In case of a wrong connection, a LED is blinking
on the display.
