ABSOPULSE Electronics has added its 1kVA addition to its line of compact, low profile DC-AC inverters with 3-phase pure sine output voltage. The use of the latest silicon carbide semiconductor technology contributes to 90% conversion efficiency at full load, ensuring high power density and significantly smaller size than earlier 3-phase 1kVA inverters. The inverters are typically used for testing 3-phase equipment in engineering labs, powering motor-driven systems and other industrial equipment.
The inverters provide 3-phase outputs of 208Vrms continuous (line-to-line) at 60 or 400Hz, or 380Vrms or 400Vrms continuous at 50 or 60Hz. They operate from 48V, 96V, 110V, 125VDC or custom DC input voltages. The input and output are filtered for low noise.
The input meets EN55022 Class A with wide margins; Class B is available on request. Custom electrical configurations, remote shutdown or enable and other options are also available.
High quality built-in fans and additional conduction via the baseplate provide sufficient cooling ensure 1,000VA continuous output power over a 0°C to +50°C operating temperature range without de-rating. Wider temperature ranges are available on request. The compact, ruggedly constructed inverters measure 280x67x356mm.
The printed circuit boards are conformal coated for immunity to humidity and airborne contaminants. Heavy ruggedising ensures that the units can withstand high levels of shock and vibration (IEC 61373 Cat 1 A&B).
Electronic protection includes 2250VDC input to output isolation, inrush current limiting, reverse polarity protection, and output current limiting with short circuit protection. The three phase inverters meet the requirements of C22.2 No. 107.1-01, UL 458, EN/UL60950-1 and equivalent industrial standards.
