The Phoenix Contact QUINT-PS/3AC/48DC/20 belongs to the Quint power supply series, which are primary-switched 24 V power supplies of 60 - 960 W. With a regulated and adjustable output voltage these devices feature a high level of efficiency and compact design. International approvals and a wide-range input guarantee worldwide, universal usage. An integrated function monitoring feature diagnoses unreliable operating states. The QUINT-PS/3AC/48DC/20 provides continuous full output power in unstable networks when power outages lasting more than 20 ms occur or a phase fails. The POWER BOOST power reserve ensures that more complex consumers, for example, capacitive loads with high switch-on currents are activated.
