Eltako 33000008 Phase-fired dimmer Suitable for light bulbs: LED bulb Grey

Phase dimmer with DALI control input for DIN EN 60715 TH35 mounting rail. 98x17.5x56mm. Protection class IP20. Suitable for dimming of 230V LED retrofit lamps via DALI. Conversion of the DALI dimming level into a voltage with phase section or phase section. The minimum dimming level (MIN LEVEL) can be set via DALI. Additional operating mode as switch (DT7 compliant) from firmware 3.5. The module represents a node on the bus and can be addressed accordingly. Double connection terminals for simple looping of the DALI bus. Dimming range 0.1%-100%. Supply voltage 230V AC. Output load range 10-300W. High efficiency· Configuration via PC software DALI Cockpit. Function: The DALI-PD is based on the standard for DALI Control Gears (IEC 62386-102) and Device Type 4 devices (IEC 62386-205) as an interface between classic dimming technology (phase dimming) and DALI. The DALI-PD interface converts the desired dimming level into a corresponding voltage signal with a phase cut on or off. Depending on the load, the universal dimmer operates as a phase angle control or phase angle dimmer. The operating mode can be queried via DALI (DT4). The dimming characteristic is logarithmically scaled according to DALI standard. The phase and section control supplies a cut-off sine voltage. THE PHYSICAL MINlevel is 3%. From firmware version 3.5 onwards, the DALI-PD has another operating mode. You can switch from the DT4 (phase dimming) mode to DT7 (switch). In this mode, the DALI PD behaves like a switch. The behavior in this mode corresponds to the DALI standard for DT7 devices (IEC62386-208). In this mode, the switching characteristic is determined by comparing the virtual lamp power level (VDAP) with 4 switching thresholds. The virtual lamp power level (VDAP) corresponds to the dimming value of a DALI ECG and is subject to the corresponding properties (limitation by MINLEVEL and MAXLEVEL, dimming speed by FADETIME and FADERATE). For each dimming direction there are 2 switching thresholds, which are used for comparison with the virtual lamp power level: A threshold with the value MASK is inactive and is not used for comparison. Fading is used to implement on and off delays. The device is supplied by the DALI bus, therefore THE SYSTEM FAILURE LEVEL is only partially supported. With current devices (recognizable by firmware >4.0) a selection can be made between 0%,100% and MASK, with older devices the SYSTEM FAILURE LEVEL is fixed - with the 25W variant 100% is output, with the 300W variant 0% is output.
