Description
In addition to the usual functions of DIN rail power supplies, such as the output voltage adjustment, the series also has an output power adjustment. Thus, the output current can be adjusted through external voltage 1-10 V DC, PWM signal or resistance and offers the user to provide flexibility.
The series DRA-40 can be used on TS-35/7.5 or TS-35/15 DIN rail mounted. It has a 90-264 V AC input voltage range and 12 or 24 V DC output voltage. Thanks to its high efficiency of up to 87%, the power supplies also in ambient temperatures from -30°C to +70°C with simple air convection.
Other features are short-circuit, overload and overvoltage protection and an LED display for power on.
The series DRA-40 is certified according to UL/CUL/CB/TÜV/CE and meets the requirements of the IEC 60950-1 limited power source (LPS). Suitable applications are machine test systems and plant cultivation systems with LED light source.
