NCM6 Series
Isolated 6W Wide Input Single & Dual Output DC/DC Converters
SAFETY APPROVAL
UL 60601
The NCM6 series is pending recognition by Underwriters Laboratory (UL) to the 3rd edition of 60601 and provides 2 MOOP (means of operator protection) based upon a working
voltage of 250 Vrms max., between Primary and Secondary.
UL 60950
The NCM6 series is pending recognition by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 250Vrms.
FUSING
The NCM6 Series of converters are not internally fused so to meet the requirements of UL an anti-surge input line fuse should always be used with ratings as defined below.
Input Voltage, 5V 3A
Input Voltage, 12V 2A
Input Voltage, 48V 1A
All fuses should be UL recognized and rated to at least the maximum allowable DC input voltage.
CHARACTERISATION TEST METHODS
Ripple & Noise Characterisation Method
Ripple and noise measurements are performed with the following test configuration.
C1
1μF X7R multilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC/DC converter
C2
10μF tantalum capacitor, voltage rating to be a minimum of 1.5 times the output voltage of the DC/DC converter with an ESR of less
than 100mΩ at 100 kHz
C3
100nF multilayer ceramic capacitor, general purpose
R1
450Ω resistor, carbon film, ±1% tolerance
R2
50Ω BNC termination
T1
3T of the coax cable through a ferrite toroid
RLOAD
Resistive load to the maximum power rating of the DC/DC converter. Connections should be made via twisted wires
Measured values are multiplied by 10 to obtain the specified values.
