Feb 2008 - Universal 120 W DC/DC converters
The DIMENSION CD5 series is a complete range of new DIN-rail mount DC/DC converters. The field applications of these units is very diverse:
- Generation of a stabilized control voltage in battery powered applications.
- Galvanic isolation to avoid earth (ground) loops.
- Mobile applications in ships, fork-lift, trucks, etc.
- Improves the 24V regulation at the end of long wire run.
Voltage drops in long wire runs are frequently under-estimated. If for example, a motor starts and draws a high current, this can lead to a significant voltage loss causing control components to lose function. This is where the CD5.241 can help clean up the "dirty" voltage and deliver a stabilized 24V. All CD5 converters have input to output isolation, are rated at 120W (CD5.121: 96W) and a temperature range from -25degC to +60degC. The units can deliver an additional 20% power reserve and can be operated at this level continuously below +45degC. The shallow depth of the units permits installation in the usual 120mm on-machine-cabinets and the width of only 32mm saves space on the DIN rail. Other features include a built-in soft start, electronic inrush current limitation, input polarity protection and the comprehensive approvals package. The CD5.241-S1 has two built-in relay contacts. The "Input-Low" contact can be used to detect a battery that is discharged and the "DC-OK" contact makes it possible to build redundant systems. This unit is equipped with quick-connect spring-clamp terminals for the 24V and a plug connector with screw terminals for the relay contacts.
