1000VA railway quality pure sine wave inverters deliver convection cooling
ABSOPULSE ELECTRONICS RSI 1K-HSA-F31 series of railway quality dc-ac inverters use field-proven microprocessor controlled high frequency PWM technology to generate up to 1000VA output power with pure sine wave output voltage. Units are an addition to firm’s line of power conversion products that are cooled by natural air convection; no forced air or attachment to a heatsinking surface is required. Cooling is via a heatsink assembly block with fins attached to the under-surface of the chassis. Additional cooling is provided by natural convection through the cooling slots. The heatsink assembly also allows for mounting on uneven and thermally non-conductive surfaces such as brick walls, plastic and wood. The units are rated for operation over a -25C to +55C ambient temperature range for full specification without derating. Products are available with input voltages of 36Vdc (25–51V range), 48Vdc (33-67V), 72Vdc (50-101V), 96Vdc (67-135V), 110Vdc (77-154V) or custom. A 24Vdc (17-34V) input version is available with derating to 750VA output power.
