Lambda UK is expanding its range of DPP series DIN rail power supplies with the introduction of new 240W models. The DPP240 complements the recently introduced DPP120 supplies, and with typical efficiency reaching an impressive 90 per cent, is suited to use in factory automation, industrial control systems and test equipment applications.

The DPP240 is low-cost yet feature-rich, with power factor correction and a switch function that allows up to three units to be connected in parallel (droop mode). The supplies are convection cooled and can operate at full power over a wide temperature range of -25 to 61degC, derating linearly at 2.5 per cent of a degree above 61 to 71degC. Other features include over-current and over-voltage protection.

Offering either 24V or 48V outputs, the DPP240 has a nominal 115/230V AC autoselect input range. Load regulation is +/-1 per cent in single-mode and +/-5 per cent in parallel mode, with ripple and noise below 100mV. A DC Good relay is provided on the 24V model, and red and green LEDs indicate output status on all models.

Measuring just 125 x 83 x 126mm, the DPP240 units mount on either a TS35/7.5 or TS35/15 DIN rail, offering a flexible option for applications, including process control, automotive, chemical processing, burn-in and test. As with existing models in the DPP Series, the DPP240 is approved to UL508 safety standard for industrial control equipment. Further safety approvals include UL60950-1 and EN 60950-1. The DDP240 meets Class B EMC compliance and is PFC compliant to EN 61000-3-2.

All models carry a two-year warranty and are CE marked.
