Lambda has expanded its line-up of the popular 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%, is suited for use in factory automation, industrial control systems and test equipment applications.

The DPP240 is low cost and 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°C to +61°C, derating linearly at 2.5% of a degree above 61°C to 71°C. Other features include over current and over voltage protection.

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

Measuring just 125mm x 83mm x 126mm, the DPP240 units will mount on either a TS35/7.5 or TS35/15 DIN rail offering engineers a flexible option for applications, including process control, automotive, chemical processing, burn-in and test. As with existing members in the DPP Series, the DPP240 is approved to UL508 safety standard for industrial control equipment. Further safety approvals include UL60950-1 and EN60950-1. The DDP240 meets Class B EMC compliance and is PFC compliant to EN61000-3-2. All models carry a two-year warranty and are CE approved.
