300VA Watertight, Dustproof Railway Sine Wave Inverter by ABSOPULSE

RSI 300-IP66

ABSOPULSE Electronics has recently released the RSI 300-IP66 series of railway grade DC-AC sine wave inverters. The units are packaged in IP66 watertight, rugged, dustproof, die-cast aluminum enclosures.

The internal module is ruggedized and the boards are conformal coated for protection from shock, vibration and humidity. The inverters are also immune to oil, salt, fog, insects and sand. They comply with EN50155 railway standards and meet the requirements of EN 55022 Class B and EN 50121-3-2 conducted and radiated standards. The series is also suitable for operation in heavy industry, military, mining, marine and other heavy-duty environments.

Cooling is by conduction and convection via the walls of the IP66 enclosure. Minimum operating temperature range is -25°C to 50°C without derating. Extended temperature ranges are available on request. The chassis measures 360mm x 160mm x 90mm (14.1in x 6.3in x 3.5in) and weighs approximately 4.6kg (10lb).

These 300VA microprocessor-controlled high-frequency PWM inverters deliver 115Vac or 230Vac continuous at the required frequency. They accept nominal inputs of 48Vdc, 72Vdc, 96Vdc or 110Vdc with wide ranges. Line/load regulation is ±3% from no load to full load. Efficiency is typically 80% at full load. Electronic protection includes 3,000Vdc input-output isolation, inrush current limiting, reverse polarity protection, output current limiting with short-circuit protection and thermal shutdown with automatic recovery in case of insufficient cooling.
