TDK presenta convertitori DC-DC isolati programmabili per montaggio su guida DIN con potenze di uscita di 120W e 240W e ampi rapporti di conversione

TDK Corporation (TSE:6762) announces the introduction of the TDK-Lambda DDSM 120 W and 240 W programmable DC-DC converters. These products feature a wide input and output voltage range with an isolated design. The DDSM series also offers remote control and real time monitoring via Modbus over USB using the PowerCMC control and monitoring center. In addition, a digital display shows the device settings, system alarms, and status information, with the ability to be operated manually via three push buttons on the front panel.

The DDSM series was developed to offer a wide conversion ratio. Its many applications include improved voltage stability over long cable lengths, providing a higher (step-up) voltage to support system loading, offering an independent isolated voltage for Power-over-Ethernet (PoE) requirements and supporting loads requiring special operating voltages. The wide input and output ranges can assist inventory management, reducing the need to stock multiple part numbers.

The DDSM converters accept a nominal 12 to 48 V input (maximum 10.8 to 52.8 V) and can deliver a nominal output range of 5 to 55 V (4.7 to 57 V maximum). Operating efficiency at standard operation is up to 93.0 %, which reduces internal heating losses and saves energy when in standby mode. The nominal output current is 5 A for the 120 W model and 10 A for the 240 W model. A 24 V/1 A DC-OK signal is accessible from the front panel. The DDSM measures 40.0 mm wide, 116.6 mm deep and 115.0 mm high, weighing just 500 g.

Safety certification is to IEC/EN/UL/CSA 61010-1, 61010-2-201 and IEC/EN/UL/CSA, 62368-1 (Ed. 3). The series is CE / UKCA marked to the Low Voltage, EMC and RoHS EU Directives and UK regulations. The models meet EN 55032-B radiated and conducted emissions and EN 61000-6 immunity standards.
