The i7C series of non-isolated step-up / step-down converters are ideal for generating additional DC output voltage rails up to 300 W from a single output 12V, 24V or 48V AC-DC power supply. The highly efficient i7C series accepts a very wide DC input and has a wide output adjustment range. Three mechanical configurations are available; low profile open frame, baseplate construction for conduction cooling, or integral heat sink for convection or forced air cooling. A full feature Power Good signal, switching frequency synchronization and output current monitoring option is available.


The compact CUS400M series of single output AC-DC power supplies are available with 12V and 24V (15V, 19V, 28V, 36V and 48V to follow) outputs in an industry standard 3 x 5 inch package and can deliver 400W with forced air cooling or 250W with 400W peak power for extended periods of time when convection or conduction cooled.
CUS400M can be used in both Class I and Class II (no earth wire) applications and offers efficiencies of up to 94%.
An option board providing a 5V 2A or 12V 1A standby voltage, remote on/off, remote sense, DC OK signal and AC fail signal is available.
Mechanical options include metal base plate, U channel, cover and top mounted integral fan.
Safety certifications include IEC/EN/ES 60601-1 and IEC/EN/UL 62368-1 with CE marking for the Low Voltage, EMC and RoHS Directives. The units also comply with EN 55011-B and EN 55032-B conducted and radiated emissions  and meet the EN 61000-3-2 harmonics, IEC60601-1-2 Edition 4 and IEC 61000-4 immunity standards.
Typical applications include medical (B and BF type), home healthcare, dental, test and measurement, broadcast, professional audio and industrial equipment.


CUS150M is a single output 2” x 4” AC/DC supply with  IEC60601-1 3rd edition medical approval as well as IEC60950-1 and is available and is available in five mechanical formats: Open pcb, pcb with baseplate, U channel, U channel with cover and U channel with cover and integral top mounted cooling fan.
Open pcb versions provide 150W output power with forced air cooling of 1m/s, and 120W at 40 deg C ambient with convection cooling.
U channel and baseplate versions provide 150W at up to 50 deg C ambient without any forced air cooling when mounted to a chassis.
It meets class B levels for both conducted and radiated emi and is
compliant with EN60601-1-2:2015 Edition 4 immunity requirements.      
CUS150M is suitable for both Class I and Class II installations, is available with 12V to 48V outputs and is ideal for medical and general applications that require silent operation with no fan noise.
Efficiency is up to 94%, and off load power consumption is less than 0.5 W.


The DDA DIN rail mount, non-isolated step-down converters are ideal for creating additional high current output voltages from a single output 24V or 48V AC-DC power supply. This highly efficient, compact series accepts a very wide DC input and has a wide output adjustment range with a choice of single or dual output models.


Consisting of 68 input voltage, output voltage and output power combinations, the CC-E series offers a wide choice of field proven products to suit a variety of applications. Backed by a five year warranty, the light weight converters have a metal case to reduce radiated EMI and are available in through hole or surface mount packages.
