Product
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.

SW/CW Series
-
The SW and CW Series are highly efficient, single output DC/DC converters. Proportional energy transfer techniques enable these encapsulated modular converters to maintain well regulated outputs despite large variations in input voltage. The 2:1 input range makes the SW and CW Series ideal for applications where the input dc power is derived from abattery, a motor generator or other types of poorly regulated power sources.

DP Series
-
The DP family is an economically priced high performance series of regulated DC/DC converters offering single and dual outputs. Features include MOSFET design operating at a switching frequency of 100Khz, continuous short circuit protection, LC input filter, 500 Vdc I/O isolation, and an operating temperature range of -25°C to +71°C with no derating. These miniature converters maintain excellent regulation over varying line and load conditions (0.2% for line and 0.5% for load). They are packaged in an IC compatible 24 pin DIP configuration measuring 1.25” x 0.8” x 0.4” high.
