Electronic Low Voltage (ELV) Dimmers were initially designed to regulate Electronic Low Voltage Transformers utilized in reduced voltage (12V) MR16-type fixtures. ELV dimmers and transformers are much more expensive; however, they use quieter operation, much better control, and often last longer than Magnetic Low Voltage Transformers (MLV).
هل ELV باهتة هو نفسه باهت LED؟
LEDs can only handle direct currents (DC), so using an ELV dimmer with an LED requires some driver. Diverse dimmers will affect LEDs differently. A low-frequency MLV dimmer will affect the LED in a way that contrasts with a high-frequency ELV waveform.
ELV dimmers generate reverse-phase, or “trailing edge,” waveforms. The luminosity of a connected light source governed by an ELV dimmer hinges on the balance between “on” and “off” durations during dimming adjustments. LEDs inherently function on direct currents (DC), necessitating an LED driver when coupled with an ELV dimmer. Different dimmers exert varying effects on LEDs. For instance, the influence of a low-frequency MLV dimmer diverges from that of a high-frequency ELV waveform.
An often overlooked aspect is that LEDs demand appropriate current regulation rather than voltage control for optimal performance. Transformers are designed primarily to regulate voltage, not current. Consequently, supplementary circuitry becomes imperative. Typically, this supplemental circuitry resides at the base of the LED fixture or lamp.

لماذا أحتاج إلى باهتة ELV؟
Electronic Low-Voltage (ELV) dimmers manage ELV transformers and dimmable LED power supplies, commonly utilized in settings like ELV track lighting, under-cabinet lighting, and LED strips. Installing ELV dimmers necessitates the availability of a neutral connection.
Applications of ELV Dimmers
The ELV Dimming Option finds its application in LITON General Purpose Recessed Housings and is designated “DLV” during the ordering process. For more comprehensive information, please refer to the provided specification sheets.

Benefits of ELV Dimming
- ELV dimming drivers from Liton have undergone extensive testing and gained approval from many dimmer manufacturers (refer to the list).
- They exhibit superior performance with LEDs compared to most magnetic low voltage (MLV) drivers.
- Facilitates smooth dimming down to 5%, subject to the limitations of the dimmer.
ELV Dimming Limitations
- ELV wall dimmers might cost more than incandescent or magnetic low-voltage dimmers.
- A smaller existing installation base might necessitate replacing incompatible dimmers during retrofit projects.
- ELV drivers with incandescent dimmers should be avoided to prevent malfunctions like dimmer buzzing, lamp flickering, circuit interactions, or radio frequency interference (RFI).
- All ELV drivers and dimmers require a 3-wire setup, including a neutral wire. This can lead to the need for additional wire installation in remodeling projects.
