The Kxxx1GL Series Multipulse™ SIDAC generates the multiple high voltage pulses required to ignite metal-halide lamps. Its quick turn-off characteristics allow generating a minimum of three pulses per AC half-cycle. Advantages include lower switching loss for higher pulse voltages, improved tolerance for input voltage variations, and longer pulse durations than earlier devices.
- Lower switching loss than earlier Kxxx1G Series Multipulse SIDAC
- Tighter breakover/trigger voltage (VBO) control than Kxxx1G Series
- Lower dynamic holding current (IH) than Kxxx1G Series
- Generates a minimum of three pulses per AC half-cycle
- Generates at least 20 percent higher pulse voltages
- Improved operating tolerance for the AC input voltage variations that are common in developing countries
- Longer high voltage pulse duration
- Best suited for metal-halide lamp ignition applications
