DCDC
JA/JP Series
-
The 15-Watt JA/JP series operates over an ultra wide range of 9-36 Vdc or 20-72 Vdc. Efficiencies of 80% 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 2.0” x 2.0” x 0.40”.

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.

DPS/DPD Series
-
The DPS/DPD is an economically priced series of miniature DC/DC converters offering both single and dual outputs. These unregulated converters offer the latest in MOSFET technology. Featuring efficiencies to 80% and a calculated MTBF in excess of 1,000,000 hours. Additional features include an operating temperature range of -25°C to +71°C with no derating and a LC input filter to reduce the reflected ripple. All this in a package measuring 1.1” x 1.1” x 0.5” high make these converters ideally suited for 0.75” cardspacing.

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.

GA Series
-
The GA series is an economically priced 15 watt DC/DC converter featuring ultra-wide input range, efficiencies to 85% and a continuous six-sided shielded case. Low ESRcapacitors are used both on the input and the output(s) to minimize the conductive noise. Other key features include: overvoltage protection, output trim adjustability, TTL and CMOS compatible remote on/off, short circuit protection and small size. The GA series measures only 1.6” x 2.0” x 0.40” and offers a power density of 11.7 watts/cu. in.
