GQA Industrial Quarter Brick DC-DC Converters

TDK-Lambda GQA Industrial Quarter Brick Converters are an industrial version of HQA converters. These DC-DC converters are manufactured in an open frame construction with a baseplate encapsulation and offer up to 91.5% efficiency. The GQA quarter-brick converters feature an input voltage range of 9-36VDC/18-36VDC and 1500-3000VDC isolation options. These converters operate from -40ºC to 105ºC temperature range and offer up to 120W output power. The TDK-Lambda GQA series converters are ideal for industrial applications, transportation electronics that require wide input ranges, and LED signs.
