Electronic transformers

  • for low voltage halogen bulbs,
    due to the technical reasons we recommend for LED lamps our LED power supplies[Link]
    work in full power range from “0″ to the nominal value
    do not require any minimum load to work properly, this property is ensured by latest method of matching the load and gives the user great flexibility in the type and quantity of lights connected to electronic transformer. Other electronic transformers always have a certain minimum level of the load what determines the minimum amount of light below which the system ceases to function properly. By Govena’s transformers even for bigger loads they work properly starting form 0 W.
  • dimmable with any dimmer
    both triac (leading edge) and transistor (trailing edge). This property is ensured by intelligent co-operation of the transformer with dimmer. This allows you to adjust the light intensity in the full range from 0% to 100%.
    doubles the life of halogen lamps
    determined precisely, soft supply voltage , doubles the time of
    halogen lamps work. Govena’s Transformers are free of disadvantages which conventional transformers have, such as the dispersion voltage output and stroke current at startup.
  • doubles the life of halogen lamps
    determined precisely, soft supply voltage , doubles the time of halogen lamps work. Govena’s Transformers are free of disadvantages which conventional transformers have, such as the dispersion voltage output and stroke current at startup.
  • lower energy consumption
    high efficiency of 95% results in minimal energy loss and thus less power intake
  • reliability
    our transformers have a reversible short-circuit , overvoltage, overload and thermal protection. There are protections which do not damage the system (it switches automatically off) and after elimination of the abnormal conditions the electronic transformer will work correctly (turns on automatically).
  • guarantee of quality and safety
    each single product is tested before sending to the market
    due to non-flammable enclosure transformers are successfully used in the furniture industry and interior utilities
    isolated terminals
    galvanic separation
    can be installed in casings of unknown flammable class
  • convenience
    switching on and off, dimming and brightening with a radio remote control
    easy to mount – screws built into the casings
    small and light in weight
    no noise

GOVENA has a broad offer of transformers ranging from 50W to 250W. We also manufacture transformers for industrial applications, for example 24V, with a guaranteed working life of 50 000 hours and microprocessor control.

How to use transformers with LED strips or LED lamps 12V DC

The Converter AC/DC is exclusively designed to use with electronic transformer (11,5 VAC) for LED strips and LED lamps (12 VDC). In the case of use Converter AC/DC there is also a possibility to connect the LED sources with a rated voltage 12 VAC.

The Converter AC/DC should be connected only with Govena’s electronic transformers YT50/YT60, YT70 and YT105. It is possible to use Converter AC/DC with YT150, YT210 and YT250 by connecting several converters in parallel to the electronic transformer output (with uniform load per converter).

Auto-Recovering Protection:

Recommended load:

Cooperation with light dimmers:

GOVENA’s electronic transformer YT with the Converter AC/DC can be used for the adjustment of the LED light intensity by applying light dimmer.

Recommended light dimmers:

GOVENA’s Light Dimmers:S-Z+T401MSC-EMC-URS-Z+T601MSC-EMC-URUC-LFS-Z+I401MSC-V2-UR-CS-Z+I601MSC-EMC-UR

Maximal, theoretically allowed load which will work with dimmers of given maximum wattage (dimmer+YT+KYT50+LED strip):

In the case of use dimmable LED lamps do not exceed 30% of dimmer nominal load.
