Rugged, convection cooled, DC-AC pure sine wave inverters for 24Vac industrial applications

200VA conduction/convection cooled - CSI 200-XX/24F3

CSI 200 converts 24Vdc or 48Vdc to 24Vac. Convection cooled, F3 chassis

The CSI 200-XX/24F3 and CSI 300-24/24FX series of rugged, high performance DC-AC inverters are designed for 24Vac industrial applications. The units deliver 200VA and 300VA respectively.

The industrial quality inverters use field-proven, microprocessor controlled high frequency PWM technology to deliver 24Vac isolated, pure sine wave output voltage. The CSI 200-XX/24F3 series operates from a nominal input of 24Vdc or 48Vdc. The CSI 300-24/24FX series accepts a nominal input of 24Vdc. Custom input voltages are available on request.

High frequency conversion enables compact construction, low weight and high efficiency. Efficiency is typically 80% at full load, depending on the input/output configuration required. The units are ruggedly constructed. The 200VA version is housed in a 132 x 62 x 290 mm enclosure; the 300VA have a 153 x 67 x 357 mm form factor.

The input and output are filtered for low noise. The input on both designs meets EN55022 Class A with wide margins (Class B on request). This ensures that the inverters can be used in EMI sensitive environments without additional filtering. The units are designed for compliance with C22.2 No. 107.1 – 01, UL 458 and EN/UL60950-1 standards. Electronic protection for both series includes overload, over-voltage, short circuit protection, inrush protection when connected to a DC source, and thermal shutdown with automatic recovery.

The operating temperature range for both series is 0°C to +50°C with no derating required. Cooling is by conduction via baseplate. Additional cooling is achieved by natural convection through the cooling slots. All heat generating components are installed on aluminum heatsink blocks which are thermally connected to the base plate. The units are typically chassis mounted. Requirements for custom mounting options can readily be accommodated.
