Key Features

  • Support improved conformance with energy conservation laws by providing two operating modes. 0.3 +0.1.
  • 0.05.
  • Standby mode (light loads): 3.0±0.3 Achieves better efficiency due to reduced frequency.
  • Normal mode: SIP009-P-0000C Achieves high efficiency in RCC local resonance operation with zero-cross detection.
  • Incorporating an input voltage compensation function available to a wide input range for worldwide use.
  • This function compensates.
