Wide Input Compact Housing
Power Supply
With the PSW family, AC/DC compact DIN rail switching power supplies with single phase
wide input range, Altech further expanded the power supply line. Built-in active PFC
function, these high efficient power units meet the harmonic current limitation per
EN61000-3-2. Equipped with 180 to 550Vac single phase wide input range, they can be
used in general power system applications with single phase 230Vac input or can
capture two phases from the 220~550Vac three-phase power system, which can greatly
increase the flexibility of system deployment.
With up-to-date circuit design PSW series possess up to 93% of extremely high
efficiency and can provide 100% power continuously at 50*C by only free air convection,
or operate under 70*C ambient temperature by suitable power derating. The compact
design in width helps save the precious space on the rail and also makes it up to 50%
smaller in size compare to its predecessor models. Meanwhile, with wider input range
the PSW series also has 3% higher efficiency than corresponding models, which
response to the trend of green power with energy saving concept. Other standard
functions include DC OK relay contact alarm signal output, front panel DC voltage
adjustment , as well as protection for short-circuit, overload (constant current mode, shut
down if over 3 seconds), over voltage, and over temperature. The PSW series comply
with UL508, IEC60950-1 (CB), and CE certificates and also meet the EMC requirements
of heavy industrial immunity level (EN61000-6-2). Suitable applications include industrial
control system, semi-conductor fabrication equipment, factory automation, electromechanical applications, and marine related installation.
