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, electro-mechanical applications, and marine related installation.
