D1SE DIN Rail Power Supplies

The TDK Lambda entry-range series comes with an AC and DC input and is optimized for essential functionality, without compromising on performance or quality. With efficiencies of up to 95.1%, energy consumption and internal losses are reduced, lowering internal component temperatures and enhancing long-term product reliability.

Equipped with push-in wire terminations, the cost-effective D1SE can be quickly and reliably mounted, reducing installation times or even enabling robotic automation. In addition to a conventional 100 V_AC to 240 V_AC nominal input, the D1SE is safety certified for operation from a 93 V_DC to 300 V_DC supply. Responding to market demand, the DC input is addressing applications where the energy supply is coming from a common DC bus voltage or a battery. Its compact size and easy installation make the D1SE series an optimal choice for a variety of control cabinets, machinery, and production systems.

The 120 W rated model can deliver a boost power of 156 W for 80 seconds, the 240 W rated model 312 W for 10 seconds, and the 480 W rated model 552 W for an extended 200 seconds. The 24 V output can be adjusted from 22.5 V to 29 V to allow compensation for cable drops, redundancy modules, or setting to non-standard output voltages. All three power supplies are available with or without a DC-OK contact. For applications in challenging environments, a printed circuit board coating option is available.

The units are housed in a rugged metal enclosure with a width of 38 mm for the 120 W models, 44 mm for the 240 W, and 60 mm for the 480 W. This narrow design saves space on the DIN-rail for other components, reducing cost. All models feature a high-quality electrolytic capacitor which extends lifetime, further reducing costs for users. The warranty is three years.

Input-to-output isolation is 5000 V_DC, input-to-ground 3100 V_DC, and output-to-ground is 750 V_DC. The D1SE models are convection-cooled and rated for operation in -25°C to +70°C ambient temperatures, with derating above +55°C.

The series is certified to IEC/EN/UL/CSA 61010-1, 61010-2-201, 62368-1 (Ed.3) and IS 13252-1 standards and is CE and UKCA marked to the low voltage, EMC and RoHS Directives. It meets EN 55011-B and CISPR11-B radiated and conducted emissions. The series also complies with EN 61000-3-2 (Class A) harmonic currents and IEC/EN 61000-6-2 immunity standards.
