DIN Rail Power Supply gives 480W from wide input range

It features an efficiency level up to 95% enabling an ultra-compact case size of just 65x124x127mm ensuring maximum DIN rail space is available for system control components.

Featuring a wide range 3-phase input voltage of from 380-480VAC the unit is specified for 2-phase operation and has an MTBF of >600,000hrs. The power supply has an active input transient filter which together with active power factor correction and very low inrush current greatly simplifies circuit protection. Full output power is available over the temperature range -25°C to +60°C and a “DC OK” relay signal provides feedback to system controller. Reliable “quick-connect” spring clamp terminals are used for input and output connections simplifying installation and maintenance and the power supply has a 3-year warranty. The QT20 family includes two other models with output voltages of 36-42VDC and 48055VDC.


The QT20.241 fulfils the requirements of EN 61558-2-17, EN 60204-1, EN 61131 and EN 50178 and is approved to EN 60950-1, UL 508, UL 60950-1 and SEMI F47.

Typical applications include, industrial control equipment, office and electrical systems, control panels, communication systems and instrumentation. PULS Dimension products are available from stock in the UK.
