Product description
The SI24D series comprises 24 V DC power supplies designed for the telecommunications and power industries. Equipped with modular rectifiers and PFC circuits, they ensure high energy efficiency and a stable buffer voltage under all conditions. Support for lead-acid batteries and the option to operate in a single- or three-phase configuration enhance application flexibility. Thanks to comprehensive digital communication capabilities, including Ethernet, Web/SNMP, SI24D units enable remote monitoring and diagnostics of operating parameters. High reliability, a wide operating temperature range and a compact design mean that SI24D telecoms power stations are the preferred choice for projects where energy efficiency and the safety of power supply systems are of paramount importance.
