Eltako electronics DSZ12WDZ-3x5A Operating Instructions Manual

CT operated energy meter with settable CT ratio and MID.
Maximum current 3x5A. Standby loss 0.5 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 0.5 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

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 transformer 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.

The S0 output can be changed in the menu so that either the energy supply
(S0 in), the energy output (S0 out) or the balance thereof (S0 bidi) is trans­mitted.
