LANEUW Series
Single and Dual Output
2 Watt DC/DC Converter
4:1 Ultra Wide Input Range
DESIGN & FEATURE CONSIDERATIONS
Input Source Impedance
The power module should be connected to a low ac-impedance input source. Highly inductive source
impedances can affect the stability of the power module.
In applications where power is supplied over long lines and output loading is high, it may be necessary
to use a capacitor at the input to ensure startup.
Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to
use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100 KHz) capacitor of a 1.5uF for
the 24V and 48V input devices.
Maximum Capacitive Load
The LANEUW Series has a limitation of maximum connected capacitance on the output. The power
module may be operated in current limiting mode during start-up, affecting the ramp-up and the startup
time. The maximum capacitance can be found in the “Output Voltage / Current Rating Chart.”
Over Current Protection
To provide protection in a fault (output overload) condition, the unit is equipped with internal current
limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit
inception, the unit shifts from voltage control to current control. The unit operates normally once the
output current is brought back into its specified range.
