APPLICATIONS
Note: The A_T-1W series also are available in our company.
The A_LT-2W Series are specially
designed for applications where a
group of polar power supplies are
isolated from the input power supply
in a distributed power supply system
on a circuit board.
COMMON SPECIFICATIONS
Short circuit protection
Temperature rise at full load
Cooling

25°C Max, 15°C Typ
Free air convection
-40°C~+85°C
These products apply to:
Operating temperature range
Storage temperature range
Lead temperature
Storage humidity range
Case material
1) Where the voltage of the input
power supply is fixed (voltage
variation ≤±10%);
-55°C ~+125°C
260°C (1.5mm from case for 10 seconds)
≤ 95%
2) Where isolation is necessary
between input and output
(isolation voltage =1000VDC);
3) Where the regulation of the
output voltage and the output
ripple noise are not demanding.
Such as: purely digital circuits,
ordinary low frequency analog
circuits, and IGBT power device
driving circuits.
