MDW1000 Series  
Test Configurations  
Overcurrent 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.

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  
on the input to insure startup.  
Input reflected-ripple current is measured with a inductor  
Lin (4.7uH) and Cin (220uF, ESR < 1.0[ at 100 kHz) to  
simulated source impedance.  
Capacitor Cin, offsets possible battery impedance.  
Current ripple is measured at the input terminals of the  
module, measurement bandwidth is 0-500KHz.  
By using a good quality low Equivalent Series Resistance  
(ESR < 1.0[ at 100 kHz) capacitor of a 8.2uF for the 5V input  
devices, a 3.3uF for the 12V input devices and a 1.5uF for the  
24V and 48V devices, capacitor mounted close to the power  
module helps ensure stability of the unit.  
Peak-to-Peak Output Noise Measurement Test  
Use a Cout 0.47uF ceramic capacitor.  
Scope measurement should be made by using a BNC  
socket, measurement bandwidth is 0-20 MHz. Position the  
load between 50 mm and 75 mm from the DC/DC Converter.

A good quality low ESR capacitor placed as close as  
practicable across the load will give the best ripple and noise  
performance.  
To reduce output ripple, it is recommended that 3.3uF  
capacitors are used on output.

The MDW1000 series has limitation of maximum  
connected capacitance on the output.  
The power module may operate in current limiting mode  
during start-up, affecting the ramp-up and the startup time.
