Acopian Power Supplies has announced that its narrow-profile power supply
series is now certified to UL Safety Standards UL 60950 (Information
Technology Equipment) and UL 508 (Industrial Control Equipment), and CE
marking.
The single-output switching regulated AC/DC and DC-DC power supplies provide
up to 288W of output power, and operate from a universal input of 90-265VAC
/ 49-420Hz, single phase, or 110-350 VDC. They offer exceptional load
regulation and overall stability, along with extremely low output ripple and
noise = 150mV RMS typical.
The series consists of both forced-air and convection-cooled (fanless)
models. The forced-air units are available with either one or two fans,
depending on output power, and measure 1.7 (L) x 3.5 (W) x 9.8 inch (H).
Convection-cooled devices eliminate audible/ambient noise and vibration,
while measuring 1.7 (L) x 3.5 (W) x 8.8 inch (H).
The units offer high current limiting capabilities, and are used in a wide
array applications in which high inrush currents occur. The supplies most
frequently are employed in manufacturing, automotive, oil exploration and
refineries, power generation and distribution, and the railroad industries.
Convection-cooled units are especially well suited to industrial automation,
high-power LED lighting, test and measurement equipment, broadcast
equipment, gaming and point-of-sale equipment, and IT equipment. They are
also appropriate in communications, and motor control power, in addition to
motorized entrance gates, shades and blinds applications.
The narrow profile modules are available with 39 output voltages ranging
from 3.3VDC to 125VDC, with a +/- 0.5V or +/- 1V user-adjustment range
depending on selected model. Output voltage is adjusted by an external 1k
potentiometer or the provided internal potentiometer.
The power supplies feature power factor correction (PFC) of 0.99 at 115VAC,
60Hz and full load for compliance with EN61000-3-2. Additional electrical
specifications include 0.05% typical line regulation and 0.05% typical load
regulation.
The supplies offer power-saving efficiency up to 81% and an ambient
operating temperature range of 0C to +71C. They incorporate power factor
correction (PFC), soft-start and cold-start functions, input overvoltage and
under-voltage protection, output over-voltage protection, over-load /
short-circuit protection with automatic recovery, output inhibit, internal
EMI filtering, RFI shielding, remote sensing, and thermal protection.
