18 Vdc to 36 Vdc or 36 Vdc to 75 Vdc Inputs, 10 W and 15 W
LC/LW010- and LC/LW015-Series Power Modules:
Test Configurations
8-203(C)
Note: Input reflected-ripple current is measured with a simulated
source impedance of 12 H. Capacitor Cs offsets possible
battery impedance. Current is measured at the input of the
module.
Figure 33. Input Reflected-Ripple Test Setup
8-513(C).g
Note: Use two 0.47 F ceramic capacitors. Scope measurement
should be made using a BNC socket. Position the load
between 50 mm and 75 mm (2 in. and 3 in.) from the module.

Measurement Test Setup for Single
Outputs
8-204(C)
Note: All measurements are taken at the module terminals. When
socketing, place Kelvin connections at module terminals to
avoid measurement errors due to socket contact resistance.

Measurement Test Setup for Single
Outputs
8-808(C).d
Note: Use four 0.47 F ceramic capacitors. Scope measurement
should be made using a BNC socket. Position the load
between 50 mm and 75 mm (2 in. and 3 in.) from the module.

Measurement Test Setup for Dual
Outputs
8-863(C).a
Note: All measurements are taken at the module terminals. When
socketing, place Kelvin connections at module terminals to
avoid measurement errors due to socket contact resistance.
