Phoenix MINI-SYS-PS-100-240AC/24DC/1.5 Power Supply Unit

Power Supply Unit

MINI POWER is the extra narrow power supply unit, which is available in widths of 22.5 mm, 45 mm, and 67.5 mm (0.886, 1.772, and 2.657 in.). In addition to a 24 V version with output currents of 1 A, 2 A, and 4 A, special voltages are also available with 5 V/3 A, +/-15 V/1 A, and 10 - 15 V/2 A for connection to single-phase AC networks or to two external conductors in three-phase networks with nominal voltages of 100 - 240 V AC. Two DC/DC converters convert low direct voltages into an adjustable and regulated 24 V output voltage. With the DIN rail bus connector, the MINI-SYS-PS can be connected in parallel to supply other modules in the same system with a regulated 24 V DC voltage. Reliable startup of heavy loads is ensured by a power reserve of up to 100% – the POWER BOOST. The high level of operational safety is also ensured in complex global networks. MINI POWER also operates in applications where static voltage dips, transient power supply failures or phase failure are common. Powerful capacitors ensure mains buffering of more than 20 ms at full load.

• Extra narrow design with widths of 22.5 mm, 45 mm, and 67.5 mm (0.886, 1.772, and 2.657 in.)
• Global use due to a wide-range voltage input
• A high level of operational safety in complex global networks
• Reliable startup of heavy loads due to POWER BOOST
