Housed in a slim 76x31.5x25.8mm (2.99x1.24x1.02") DIN-Rail package, CUI has announced a family of compact DIN rail DC/DC converters. The family’s 47 modules, across three series - PYB10-DIN, PYB15-DIN and PYB20-DIN - have been designed for applications where the convenience of DIN rail mounting is required, such as industrial equipment, mobile equipment, and telecomms base stations.

Available input ranges of 9-36 or 18-75V DC make the units 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%. All models have an output range of 10-20W and with all electrical connections are easily accessible via screw terminals.

The PYB family is available in single output (3.3, 5, 12, 15, or 24V DC), dual output (±5, ±12, or ±15V DC), and in 15 and 20W 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 1,500V DC 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 with prices starting at $37.51 (USD) each in 100 unit quantities.
