Eltako electronics DSZ12WDZ-3x5A User manual

Two-way three-phase energy meter DSZ12WDZ-3x5A
with display and MID approval
GB
CT operated energy meter with settable CT ratio and MID.
Maximum current 3x5A. Standby loss 0.4 watt per path only.
Modular device for DIN-EN 60715 TH35 rail mounting.
4 modules = 70mm wide and 58mm deep.
Accuracy class B (1%). With S0 interface.
The directly measuring two-way three-phase energy meter measures active energy by
means of the currents flowing between inputs and outputs. The internal power
consumption of 0.4 watt active power per path is neither metered nor indicated.
The active energy will be added dependently on the sign.
Energy consumption is displayed with a right arrow and power supply with a left
Arrow each over the active bar in the display.
3 phase conductors with max. currents up to 5A must be connected.
The inrush current is 10mA.
The N terminal must always be connected.
The 7 segment LC display is also legible twice within a period of 2 weeks without
power supply.
Power consumption is shown by a bar flashing at a rate of 10 times per kWh. On the
right next to the display are the keys MODE and SELECT. Press them to scroll through
the menu. First the background lighting switches on. After that, the total active energy
per reference and supply, the active energy of the resettable memory per reference and
supply as well as the instantaneous values of power, voltage and current per phase
can be displayed.
The CT ratio can also be set. It is set to 5:5 at the factory and blocked with a bridge over
the terminals which are marked with 'JUMPER'. To adjust the CT ratio to the installed trans-
former remove the bridge and reset the energy meter according to the operation manual.
Then block it again with the bridge. Adjustable current transformer ratios: 5:5, 50:5, 100:5,
150:5, 200:5, 250:5, 300:5, 400:5, 500:5, 600:5, 750:5, 1000:5, 1250:5 and 1500:5.
Error message (false)
When phase conductor is missing the bar 'false' appears and the corresponding phase
conductor is also shown in the display.
Important! Before working on the current transformers disconnect the voltage paths of the
energy meters.

Typical connection:
4-wire-connection 3x230/400V
Operating instructions:
The energy will be added dependently on the sign. Positive power in the energy meter
stands for energy reference, a negative power for energy supply.
