CUI Introduces Low Power DIN Rail DC-DC Converter Family in a Slim Package

Designed to speed and simplify installation in industrial environments

TUALATIN, Ore. — CUI Inc today announced a compact DIN rail dc-dc converter line to ease installation in industrial environments.

The converter family is housed in a slim 76 x 31.5 x 25.8 mm (2.99 x 1.24 x 1.02 in) DIN-Rail package with all electrical connections easily accessible via screw terminals.

It has been designed for applications where the convenience of DIN rail mounting is required, such as industrial equipment, mobile equipment, and telecom base stations. The family’s 47 modules, across three series - PYB10-DIN, PYB15-DIN, and PYB20-DIN – have an output range of 10~20 W.

Available input ranges of 9~36 Vdc or 18~75 Vdc make the units ideally suited to battery-driven applications, where charging and discharging conditions require a wide input range.  The devices’ -40° to +85°C operating temperature range also allows the series to work reliably in harsh environments. For applications where power consumption is a concern, the PYB series delivers efficiencies reaching 91%.

The PYB family is available in single output (3.3, 5, 12, 15, or 24 Vdc), dual output (±5, ±12, or ±15 Vdc), and in 15 and 20 W versions, triple output (3.3/±12, 3.3/±15, 5/±12, or 5/±15) models. Outputs are fully regulated to within ±0.5% for overall line input conditions and ±1.0% for all load conditions. Input to output isolation of 1,500 Vdc is provided across the range of models.

Single output 15 W and 20 W models offer an output trim that allows ±10% nominal output adjustment. All parts include a remote on/off feature. Protections include continuous short circuit, over current and over voltage. The PYB series meets CISPR22/EN55022 Class B standards with limited external components. An optional heat sink is also offered on most models for improved thermal performance.

The PYB10-DIN, PYB15-DIN, and PYB20-DIN Series are available now through distribution starting at $ 37.51 for 100 pieces.  Please contact CUI for volume pricing.
