Switching relay

ER12DX-UC

ER12DX/110-240V

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%.

230V LED lamps up to 200W (with active DX up to 600W), incandescent lamp load 2000W. No standby loss.
Modular devices for DIN-EN 60715 TH35 rail mounting. 1 module = 18mm wide, 58mm deep.
ER12DX-UC: Universal control voltage 12..230V UC.
ER12DX/110-240V: Control voltage 110-240V AC.
Contact position indicator with LED.
By using a bistable relay coil power loss and heating is avoided even in the on mode.
The relay contact can be open or closed when putting into operation. It will be synchronised at first operation.
This relay is not suitable to feed back the switching voltage signal of a dimmer switch. Use only relays ESR12DDX-UC, ESR12NP230V+UC or ESR61NP-230V+UC for this purpose.
1 NO contact potential free 16A/250V AC. With the ELTAKO-Duplex technology the normally potential-free contacts can still switch in zero passage when switching 230V AC 50Hz and therefore drastically reduce wear. Simply connect the neutral conductor to the terminal (N) and L to 1(L) for this. This gives an standby consumption of only 0.1 Watt.

If the contact is used for controlling switching devices which do not perform zero passage switching themselves, (N) should not be connected because the additional closing delay otherwise causes the opposite effect. Same terminal connection as electromechanical switching relay R12-100-.

Typical connections

ER12DX-UC

ER12DX/110-240V:

If N is connected, the zero passage switching is active.

EVG = electronic ballast units; KVG = conventional ballast units 1)
1) For lamps with 150W max.

For electronic ballast gears a 40fold inrush current has to be calculated. For steady loads of 1200W use the current-limiting relay SBR12.
Due to different lamp electronics and depending on the manufacturer, the maximum number of lamps may be limited, especially if the wattage of the individual lamps is very low (e.g. with 2W LEDs).

The strain relief clamps of the terminals must be closed, that means the screws must be tightened for testing the function of the device. The terminals are open ex works.
