The quality of the power supply unit alone can’t guarantee a fault-free, 24-V supply. Power failures, extreme variations in the mains voltage or a faulty load can bring plant operation to a standstill and cause high costs. That’s why processes and plants that are critical for a company’s business generally require additional protection measures. SITOP add-on modules protect your production from a wide variety of potential hazards on the primary and secondary side and allow the completely flexible expansion of SITOP power supply units up to total, all-round protection.
As a ballast unit for SITOP power supplies, SITOP inrush current limiters reliably reduce inrush currents like those caused by the rectifier circuit on the input side with capacitor charging – as in the case of pulse-controlled power supplies. An inrush current limiter can also significantly extend the service life of the connected loads.
Maximum service life of current-sensitive components like relays thanks to reduced current inrushes
Space-saving, thanks to narrow width of only 18 mm
Suitable for LOGO! modules and sub-distribution boards thanks to stepped profile
Flexible installation on the DIN rail, on the wall or in various other locations
Maximum plant configuration enabled
Flexible application options at temperatures ranging from -40° Celsius to +70° Celsius
Reliable system protection against a wide variety of potential hazards
Power failures, extreme variations in the mains voltage or a faulty load can bring plant operation to a standstill and cause high costs.
