What this company actually does
Delta Electronics (Thailand) is the Thai-listed arm of the Delta Group (Taipei-listed parent), one of the world's largest makers of switching power supplies. Core product scope spans industrial power supplies, telecom power, data-centre UPS, and increasingly EV infrastructure. FY2024 group revenue above THB 150B makes DELTA one of the largest SET-listed industrial companies by revenue.[]
The EV segment is the single largest listed Thai exposure to BEV content growth. Delta manufactures EV chargers (AC, DC fast), onboard power electronics (DC-DC converters that step down battery voltage for auxiliaries), and DC fast-charging network infrastructure for utilities and charging operators. As Thai BEV share rises and as Delta supplies EV infrastructure across ASEAN and Europe, the EV segment revenue growth outpaces the traditional power-supply business.[]
