DESCRIPTION
The PSAKC series of AC/DC power supplies provides 20 watts of output power in a 2.76” x 1.89” x
0.87” encapsulated PCB mountable package. This series consists of single, dual, and triple output
models with a universal input range of 90-264VAC (100-375VDC). Some features include low ripple
and noise, -25°C to +70°C operating temperature range, and over current, over voltage, and short
circuit protection. The PSAKC series also has two types of screw terminal mechanical options
available. All models are RoHS compliant and have UL/cUL, CE, and CB safety approvals.

NOTES
1. Triple output models require a minimum of 10% loading on the output to maintain specified regulations. Operation under no-load conditions will not damage these
devices; however, they may not meet all listed specifications.
2. Load regulation for triple output models:
Main output (V1): 20% to 100% with 20% to 100% balanced on auxiliaries.
Auxiliary outputs (V2 & V3): 20% to 100% balanced on all outputs.
3. Cross regulation for dual output models: asymmetrical load 25% / 100% FL
4. Cross regulation for triple output models:
Main output 100% load, auxiliary 100%, other auxiliary 25% to 100%.
Auxiliary outputs (V2 & V3): Main output 100% load, auxiliary 100%, other auxiliary 25% to 100% or main output 25%, auxiliary 25%, other auxiliary 25% to 100%.
5. Screw terminal mechanical options available (see page 4). Please call factory for ordering details.
