ACDC
EC Series
The EC Series of line operated power supplies features near constant efficiency over theentire rated input voltage range. These electrically identical families employ a highly efficient, closed loop ripple regulation circuit, which contains a low pass filter. Each stage, transformer, filter and regulator is engineered for maximum efficiency.
