D1SE DIN Rail Power Supplies

The TDK Lambda D1SE 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.
