Redundancy Power Supply - 24V, 10 A, 240 W, Single-phase Input
Safety and Protection
Features
Isolation resistance
Min 500 MΩ At delivered condition between input and output, measured with 500V DC
Min 500 MΩ At delivered condition between input and PE, measured with 500V DC
Min 500 MΩ At delivered condition between output and PE, measured with 500V DC
Min 500 MΩ At delivered condition between output and DC OK contacts, measured with 500V DC
PE resistance Max 0.1O Ω Resistance between PE terminal and the housing in the area of the DIN rail mounting bracket.
Output overvoltage protection
(1)
Typ 30.5V DC
In case of an internal defect, a redundant circuit limits the maximum output voltage. The output
shuts down and automatically attempts to restart.
Max 32V DC
Class of protection I
According to IEC 61140
A PE (Protective Earth) connection is required
Degree of protection IP 20 According to EN/IEC 60529
Over-temperature protection
(2)
Included
Output shut-down with automatic restart. Temperature sensors are installed on critical
components inside the unit and turn the unit off in safety critical situations, which can happen e.g.
when ambient temperature is too high, ventilation is obstructed or the derating requirements are
not followed. There is no correlation between the operating temperature and turn-off temperature
since this is dependent on input voltage, load and installation methods.
Input transient protection MOV (Metal Oxide Varistor) For protection values see EMC on page 19
Internal input fuse Included Not user replaceable slow-blow high-braking capacity fuse
Touch current (leakage current)
Typ 0.14 mA / 0.36 mA At 100V AC, 50Hz, TN-,TT-mains / IT-mains
Typ 0.20 mA / 0.50 mA At 120V AC, 60Hz, TN-,TT-mains / IT-mains
Typ 0.33 mA / 0.86 mA At 230V AC, 50Hz, TN-,TT-mains / IT-mains
Max 0.18 mA / 0.43 mA At 110V AC, 50Hz, TN-,TT-mains / IT-mains
Max 0.26 mA / 0.61 mA At 132V AC, 60Hz, TN-,TT-mains / IT-mains
Max 0.44 mA / 1.05 mA At 264V AC, 50Hz, TN-,TT-mains / IT-mains
