The PSAOCH series of AC/DC switching power supplies provides up to 4 watts of output power in a

1.44” x 1.06” x 0.67” encapsulated PCB mountable package. This series consists of single and dual

output models with a universal input range of 90-305VAC (120-430VDC). Some features include low

ripple and noise, -40°C to +70°C operating temperature range, and over power, over voltage, and

short circuit protection. All models are RoHS compliant and have UL/cUL and CE safety approvals.

NOTES

1. Dual output models require a minimum 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. Ripple & Noise is measured 20MHz limited bandwidth and with 0.1µF and 47µF capacitors in parallel across the output.
