The Enertex® KNX HV Dimmer is a dimming actuator for all types of dimmable 230 VAC lamps. Each channel provides a dimming power of 250 W, and when up to 4 channels are operated in parallel, a total power of 1000 W is possible.
The dimmer is available in 4-channel NEW (from 2025-12-15) and 8-channel versions.
Compact
With its eight dimming channels in just six module widths, the device sets new standards in space efficiency. This means that only half as much space is required in the distribution box compared to conventional dimmers.
The smaller 4-channel version requires an installation width of 4 modular units.
Easy commissioning
With the help of the display and control buttons, the dimmer including wiring and lamps can be operated and tested without a PC or ETS software. The display of the current power values also allows monitoring of the power of the installed lighting.
Automated lamp calibration
Using the measurement function, the optimal dimming parameters for the lamps on a channel are automatically determined and applied. This eliminates the need for time-consuming manual adjustment of minimum and maximum brightness levels and the ideal dimming curve.
Dimming behavior
The dimmer uses two innovative technologies to ensure smooth, flicker-free, and harmonious dimming across the entire dimming range: the lamp correction method (LKV) and the low-light stabilization method (SSV). In addition, selectable dimming curves provide the flexibility to adjust the desired dimming ramp.
Lamp monitoring
With this function, the dimmer can detect the failure of a single lamp within a lighting circuit and send it on the bus. This allows the building management system to identify a failure remotely and organize a lamp replacement.
Protection functions
The device features a range of protective functions to prevent damage in the event of a fault. Short-circuit, overload, overtemperature, and overvoltage shutdown mechanisms protect the device from damage. An additional configurable lamp protection function also safeguards the connected lamps and their supply lines from overload.
No LED ghosting
The Enertex® KNX HV Dimmer also effectively addresses the issue of residual currents. In conventional dimmers, residual currents often cause low-power LED lamps to emit a faint glow even when switched off. The high-quality control of the new Enertex dimmer reduces residual currents to as little as one-tenth of those found in other dimmers. As a result, lamps remain completely dark when turned off.
Time-dependent dimming
Different switching behaviors for day and night are supported, as well as time-controlled dimming. The latter enables brightness control based on the time of day. The reference points can be defined either as absolute times or relative to sunrise and sunset (astro function).
Wake-up light / Sleep light
These comfort functions create light sequences that gradually brighten or dim. This allows for a gentle wake-up or a calm transition into sleep.
Timer
The device features an extensive timer with 64 switching times for up to 64 group addresses, including comprehensive logic functions, a holiday calendar, and an integrated astro function. This allows, for example, lighting to be switched on or off depending on sunrise or sunset.
Blink function
The lock function can trigger blinking at one-second intervals – ideal as a visual warning signal or for automatic activation via the alarm system.
Energy meter
The device has an integrated energy and electricity cost meter. With that energy consumption can be monitored, leading to savings on energy costs.
