50 VA rugged pure sine wave inverter targets CCTV systems

Fri, 07/11/2014 - 10:29pm


sine wave inverter for CCTVABSOPULSE Electronics (Ottawa, Canada) has released the CSI 50-24/24-FT, an industrial quality low voltage DC-AC sine wave inverter specifically designed for powering CCTV systems. The inverter uses field proven, microprocessor controlled high frequency PWM technology to convert the DC input to a 24 VAC pure sine wave output. Regulation is better than ±2 percent from no load to full load across all line and load conditions. Efficiency is higher than 80 percent at full load. New topology streamlines the circuitry, resulting in high MTBF at low cost. The input and output are filtered for low noise. The input meets the requirements for EN55022 Class B for conducted noise and radiated emissions. This ensures that the unit can be used in EMI sensitive environments, including residential areas, without any additional filtering. Additional features of the CSI 50-24/24-FT units include:

  • Main cooling via natural convection; the heat generating components are also conduction cooled to the base plate.
  • Operation over a 0°C to +50°C temperature range.
  • A robust aluminum chassis housing.
  • Inrush current limiting, reverse polarity protection, input transient clamping, output current limiting and short-circuit protection.
