1 normally open contact, not potential-free, 600VA and 1-10V control output 40mA. Standby loss only 0.9 watts. Modular device for mounting on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. The SUD12 control unit can be used in two circuit types. Circuit type 1-10V output: In this circuit type, in conjunction with a universal dimmer switch EUD12D or MFZ12PMD, electronic ballasts and transformers with a 1-10V interface can be controlled with up to 40mA total control current. The EUD12D or MFZ12PMD is controlled locally and, if necessary, centrally using buttons on the universal control voltage input and causes the SUD12 to control the 1-10V output 0/Q1 for the interface via the Y1/Y2 connections. The load is switched on and off using a bistable relay on the EVG output. Switching at zero crossing to protect contacts. Switching capacity of fluorescent lamps or low-voltage halogen lamps with EVG 600VA. By using a bistable relay, there is no coil power loss and no heating as a result, even when switched on. After installation, wait for the automatic short synchronization before connecting the switched consumer to the mains. A directly dimmable lamp can be connected to the EUD12D universal dimmer switch at the same time. The EUD12D or MFZ12PMD universal dimmer switch can also be expanded with LUD12 power add-ons for directly dimmable lamps and lights. 1-10V input circuit type: In this circuit type, in conjunction with an LUD12 power booster connected to the X1/X2 connections, the output of a 1-10V control unit at A1/0 can be converted into a direct dimming function. Switching on and off is also done externally at L of the SUD12. The rotary switch of the LUD12 must be set to the additional lights position. Additional LUD15 power boosters can be connected to the SUD12 control unit in the power increase with additional lights circuit type. A 100 K potentiometer for brightness regulation can also be connected directly to the control input A1/0. If the input A1/0 is disconnected, the LUD12 dims to maximum brightness.
