DIN rail-mounted DC power supply buffer module 6EP series

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. Bridging short-term power failures Power failures usually last only a fraction of a second – but they can cause time- and cost-intensive damage. Used in combination with the 24-V DC power supply units, the buffer modules bridge short-duration voltage dips with their electrolytic capacitors and reliably preserves interruption-free operation. Fast and easy DIN rail mounting Connects the power supply unit with only two lines Protection against short power failures. Buffer time depending on load current: - SITOP PSE201U: 200 ms/40 A, 400 ms/20 A, 0,8 s/10 A, 1,6 s/5 A, max. up to 10 s - SITOP BUF1200: 300 ms/40 A, 600 ms/20 A, 1,2 s/10 A, 2,4 s/5 A - Multiplication possible using parallel switching, with PSE201U max. up to 10 s BUF1200 also available as explosion-proof variant Longer power failures bridged by SITOP DC UPS for up to several hours 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.
