DDSM Series
The DDSM series offers high-performance DC-DC converters with 120 W and 240 W output power in a compact, lightweight design. The DDSM series is highly flexible thanks to its isolated design and wide input and output voltage range, allowing it to be used for a variety of applications.
The DC-DC converter series is fully digitally controlled, with a 7-segment display showing precise system values, status and alarm codes. The system can be operated directly via three push buttons. An advanced communication interface is also available for operating and maintaining the DDSM using the PowerCMC software tool and Modbus over USB.
An additional DC-OK contact provides further signaling opportunities. Thanks to its push-in terminals, the DDSM series guarantees simplified installation and reliable performance in diverse industrial environments.
Flexible & Versatile
Thanks to the wide input and output voltage range and isolated design, the two DDSM models can be used for a variety of applications, reducing inventory and increasing flexibility. These compact, lightweight models are available with 120 W or 240 W output power to suit different requirements.
Advanced connectivity
The DDSM Series features Modbus over USB, enabling seamless integration, remote control and real-time monitoring. The DDSM is compatible with the comprehensive PowerCMC control and monitoring centre, providing efficient system management and diagnostics.
User-friendly operation
A clear digital display shows precise system values, status and alarm codes, all of which can be easily set up and adjusted via intuitive push-button controls. The option of local or remote operation provides maximum convenience.
Easy installation & maintenance
Push-in terminals and a compact design simplify installation, wiring and maintenance. The robust design ensures reliable performance in a variety of industrial settings. They also reduce installation time and minimise the need for tools.
