JAHW050A and JAHW075A Power Modules:
Test Configurations
8-203 (F).l
Note: Measure input reflected-ripple current with a simulated source
inductance (L
TEST
) of 12 μH. Capacitor C
S
offsets possible bat-
tery impedance. Measure current as shown above.
Figure 12. Input Reflected-Ripple Test Setup
8-513 (F).d
Note: Use a 1.0 μF ceramic capacitor and a 10 μF aluminum or tan-
talum capacitor. Scope measurement should be made using a
BNC socket. Position the load between 51 mm and 76 mm
(2 in. and 3 in.) from the module.
Figure 13. Peak-to-Peak Output Noise
Measurement Test Setup
8-749 (F)
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.

Design 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 mod-
ule. For the test configuration in Figure 12, a 33 μF
electrolytic capacitor (ESR < 0.7
at 100 kHz)
mounted close to the power module helps ensure sta-
bility of the unit. For other highly inductive source
impedances, consult the factory for further application
guidelines.
Safety Considerations
For safety-agency approval of the system in which the
power module is used, the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standard,
i.e.,
UL
1950,
CSA
C22.2 No. 950-95, and
VDE
0805
(EN60950, IEC950).
If the input source is non-SELV (ELV or a hazardous
voltage greater than 60 Vdc and less than or equal to
75 Vdc), for the module’s output to be considered
meeting the requirements of safety extra-low voltage
(SELV), all of the following must be true:
I
The input source is to be provided with reinforced
insulation from any hazardous voltages, including the
ac mains.
I
One V
I
pin and one V
O
pin are to be grounded, or
both the input and output pins are to be kept floating.
I
The input pins of the module are not operator acces-
sible.
I
Another SELV reliability test is conducted on the
whole system, as required by the safety agencies, on
the combination of supply source and the subject
module to verify that under a single fault, hazardous
voltages do not appear at the module’s output.
Note:
Do not ground either of the input pins of the
module without grounding one of the output pins.
This may allow a non-SELV voltage to appear
between the output pin and ground.
The power module has extra-low voltage (ELV) outputs
when all inputs are ELV.
The input to these units is to be provided with a maxi-
mum 15 A normal-blow fuse in the ungrounded lead.
