Trim_Down
For trim down an external resistor is to be connected between TRIM and Vout pins of the module.
The value of Rtrim_Down is calculated from the following relationship.
The values of Vr , R1 and Rt are as defined above.
ΔV is the adjustment trim required.
Examples:
Vout = 1.5V Trim_Up required 8% to 1.62V
Vout = 1.5V Trim_Down required 8% to 1.38V
Remote Sense:
All Murata Power Solutions SIP power modules offer an option for remote sense. The remote sense
compensates for any distribution drops to accurately control voltage at the point of load. The voltage between
the sense pin to Vout pin should not exceed 0.5V.
Safety Considerations
The NCF series of converters are certified to IEC/EN/CSA/UL 60950. If this product is built into information technology
equipment, the installation must comply with the above standard. An external input fuse of less than 50 Amps (5A to
30A recommended), must be used to meet the above requirements. The output of the converter [Vo(+)/Vo(-)] is
considered to remain within SELV limits when the input to the converter meets SELV or TNV-2 requirements.
The converters and materials meet UL 94V-0 flammability ratings.
