ACDC
EA Series
The EA 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.

TA Series 25 Watt
The 25-Watt TA series operates over an ultra wide input range of 9-36 Vdc or 20-72 Vdc. Efficiencies of 77% are typical over varying load conditions of 25% to 100%. Additional features include input reverse polarity protection, remote on/off control, logic compatible with CMOS or open collector TTL, short circuit protection with auto restart, overvoltage protection, and an operating temperature range of -25°C to +71°C with no derating. Units are packaged in a six-sided continuous shielded case for EMI/RFI protection and measure 2.5” x 3.0” x 0.83”

DCDC
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.
