Safety and protection features
Insulation resistance | Min. 500MOhm | In the delivery state between input and output, measured with 500Vdc |
Min. 500MOhm | In the delivery state between input and Chassis Ground, measured with 500Vdc | |
Min. 500MOhm | In the delivery state between output and Chassis Ground, measured with 500Vdc | |
PE resistance | Max. 0.1Ohm | Resistance between PE terminal and the housing in the area of the DIN-rail mounting bracket. |
Output overvoltage protection | Typ. 31Vdc | In case of an internal defect, a redundant circuit limits the maximum output voltage. The output shuts down and automatically attempts to restart. |
Class of protection | III | According to IEC 61140 |
Degree of protection | IP 20 | According to EN/IEC 60529 |
Over-temperature protection | Not included |
|
Input transient protection | MOV (Metal Oxide Varistor) | For protection values see chapter “EMC”. |
Internal input fuse | Included | Not user replaceable slow-blow high-braking capacity fuse |
Touch current (leakage current) | The leakage current, which is produced by the DC/DC converter itself, depends on the input voltage ripple and need to be investigated in the final application. For a smooth DC input voltage, the produced leakage current is less than 100µA. | |
