3W and 5W Encapsulated AC-DC Power Supplies with Multiple Mounting Options

CUI‘s Power Group added 3W and 5W models to its line of low-power, encapsulated ac-dc power supplies. Available in board mount, chassis mount, wire lead, and DIN rail configurations, the single output PSK S3 and PSK S5B series are housed in compact packages measuring as small as 1.46″ x 0.97″ x 0.71″ (37mm x 24.5mm x 18mm). The company says that this small size makes them well suited for space-constrained applications in low-power ITE, industrial control, automation, and consumer electronics.

CUI designed the power supplies for easy installation. The wire lead PSK S3 L and PSK S5B L series, chassis mount PSK S3 T, PSK S5B T series, and DIN rail mount PSK S3 DIN and PSK S5B DIN series support additional options for more straightforward design implementation. (See image of PSK S3 models above).

These encapsulated modules feature 4kVac input to output isolation, have a universal input voltage range of 85Vac to 264 Vac, and a wide operating temperature range from -40°C to +70°C. The series also offers single output voltages of 3.3Vdc, 5Vdc, 9Vdc, 12Vdc, 15Vdc, and 24Vdc. The power supplies also have over-current, over-voltage, and continuous short-circuit protections.

All models are certified to the new IEC 62368-1 safety standard for ICT and AV equipment, while meeting CISPR 32/EN 55032 Class A limits for conducted and radiated emissions. They carry a minimum MTBF of 300,000 hours at +25°C ambient, per MIL HDBK 217F.

The PSK S3 and PSK S5B series are available immediately with prices beginning at $8.01 per unit at 120 pieces through distribution. Please contact CUI for OEM pricing.
