EQW010-040 Series Power Modules

36 – 75Vdc Input; 1.0 to 12.0Vdc Output; 10 to 40A Output Current  
Test Configurations

CURRENT PROBE  
TO OSCILLOSCOPE  
The power module should be connected to a low  
ac-impedance source. Highly inductive source  
impedance can affect the stability of the power  
LTEST  
Vin+  
12μH  
module. For the test configuration in Figure 57 a 33μF  
electrolytic capacitor (ESR<0.1Ω at 100kHz),  
CS 220μF  
E.S.R.<0.1Ω  
mounted close to the power module helps ensure the  
33μF  
stability of the unit. Consult the factory for further  
application guidelines.

Output Filtering  
For 1.0V to 1.2V output voltage modules, an external  
capacitance of 1000uF is recommended to achieve  
monotonic start-up with very light load (2Amp).  
NOTE: Measure input reflected ripple current with a simulated  
source inductance (LTEST) of 12μH. Capacitor CS offsets  
possible battery impedance. Measure current as shown  
above.  
Safety Considerations  
Figure 57. Input Reflected Ripple Current Test  
Setup.  
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 60950-1-3, CSA C22.2 No. 60950-  
00, and VDE 0805:2001-12 (IEC60950-1).

SCOPE  
If the input source is non-SELV (ELV or a hazardous  
voltage greater than 60 Vdc and less than or equal to  
75Vdc), for the module’s output to be considered as  
meeting the requirements for safety extra-low voltage  
(SELV), all of the following must be true:  
0.01uF  
10uF  
0.1uF  
GROUND PLANE  
NOTE: All voltage measurements to be taken at the module  
terminals, as shown above. If sockets are used then  
Kelvin connections are required at the module terminals  
to avoid measurement errors due to socket contact  
resistance.

The input source is to be provided with reinforced  
insulation from any other hazardous voltages,  
including the ac mains.

One VIN pin and one VOUT pin are to be  
grounded, or both the input and output pins are  
to be kept floating.

Another SELV reliability test is conducted on the  
whole system (combination of supply source and  
subject module), as required by the safety  
agencies, 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 pins and ground.  
NOTE: All voltage measurements to be taken at the module  
terminals, as shown above. If sockets are used then  
Kelvin connections are required at the module terminals  
to avoid measurement errors due to socket contact  
resistance.  
The power module has extra-low voltage (ELV)  
outputs when all inputs are ELV.

Setup.  
All flammable materials used in the manufacturing of  
these modules are rated 94V-0, or tested to the  
UL60950 A.2 for reduced thickness.

For input voltages exceeding –60 Vdc but less than or  
equal to –75 Vdc, these converters have been  
evaluated to the applicable requirements of BASIC  
INSULATION between secondary DC MAINS  
DISTRIBUTION input (classified as TNV-2 in Europe)  
and unearthed SELV outputs.  
The input to these units is to be provided with a  
maximum 8 A time-delay fuse in the ungrounded lead.
