The supplementary circuit for energy saving lamps and LED lamps improves the dimming behaviour of ESL and retrofit LED lamps. (LED lamps that can replace conventional incandescent lamps with identical base). Energy saving lamps and LED lamps have an electric ballast integrated in their base that limits the mains voltage to a level suitable for lamp operation. This electric ballast may prevent the detection of the main voltage zero crossing that is required for proper dimming operation, with the result that the lamp may start flickering.
- Simple parallel connection to the load (neutral conductor N and dimming phase LD can be connected either way, reverse connection impossible)
- Suitable for 230 VAC
- Operation independent of the load quantity
- Maximum power dissipation during dimming 1.7W, no stand-by losses
- Snap-on DIN rail housing with practical double terminals (ZSL-REG only)
- Range: from minimum load to maximum dimmer current
