750W rugged, ac-dc power supply enables start-up in switchgear motors

EP&T Magazine   


ABSOPULSE HBC 319-A/125FTS rugged ac/dc power supply delivers 750W peak output power without fan cooling. Product provides the high peak power for the start-up of the motor in electric switchgear. The industrial grade unit generates 125Vdc at 4A, with 6A peak current for 30 seconds during the motor start-up stage. Several modules can be connected in parallel for higher output current to ensure that output voltage remains constant at 125Vdc, even during the high peak load period. The input accepts 115Vac (97-132Vac operating range) and a 230Vac input is also possible. Custom input and output options are available on request. A built-in redundancy diode provides separation between the units if used in multiple-configuration – a truly redundant system can be created with a number of units.
