IEC/EN60950-1 and IEC/EN60601-1 and IEC/EN61010-1 - CB Report and Certificate.
CE marking when applied to any EFE300M product indicates compliance with the Low Voltage Directivein
that it complies with EN60950-1 and with the ROHS Directive.
UL/CSA 60601-1 - UL + C -UL approval
UL/CSA 61010-1 - UL + C -UL approval
Fusing: Internal fuses (F1): dual fuses in the L and N line (except L option, single fuse in the live line). F8AH,
250V, 5x20mm.
Symbols:
AC DC AC/DC
If the earth terminal of the EFE300M PSU is connected to the main incoming earth conductor of the end
equipment, the installer must cover the earth symbol with a label bearing the earth symbol of IEC60417-5019.
Note: All output voltages/variants may not be available as standard units, refer to datasheet for
standard product range. These (and other variants) may be available as non-standard or custom
units, please contact our sales team for details.
Nomenclature:
EFE300M or -EFE300M models as described below:
Unit Configuration Code:
EFE300Mxy-a-b-cdef-ghijk
Where:
x = Nothing or J for Japanese models (may have non-safety differences).
y = Blank for Y2 capacitors from output to earth, P for Y1 capacitors from output to earth.
a = Channel 1 output Voltage: see Ch1 in the outputs table below, adjustment range column.
b = Standby voltage: see standby voltage table below or 0 for omitted
c = HN for Open frame, no fan, with 12V / 1A fan supply.
HU for U chassis, no fan, with 12V / 1A fan supply.
HC for Cover + chassis, no fan, with 12V / 1A fan supply.
EC for Cover + chassis, end fan (temp controlled).
NN for Open frame, no fan, no fan supply.
NU for U chassis, no fan, no fan supply.
NC for Cover + chassis, no fan, no fan supply.
CN for Open frame, no fan, with 12V / 0.25A fan supply.
CU for U chassis, no fan, with 12V / 0.25A fan supply.
CC for Cover + chassis, no fan, with 12V / 0.25A fan supply.
d = M for molex input connector or equivalent, J for JST connector or equivalent.
e = D for dual fused input or L for single fuse in the live line
f = S for standard Leakage, L for low Leakage, R for reduced Leakage, T for tiny Leakage. *
g = Y for Oring FET included or N for nothing.
h = E for enable, T for inhibit, N for no inhibit, no enable.
i = Nothing for horizontal output connector, -V for vertical output connector, -S for screw terminal
j = Nothing for standard channel 1 output voltage, -xD or -xPD where D is for units with programmed
negative load regulation, PD is for units with programmed positive load regulation, x is the voltage
of the regulation in 100mVolts and is within the Output Adjustment range (example, 7D = 0.7V of
negative load regulation, 24PD = 2.4V of positive load regulation).
k = Nothing or -x where x is three numbers from 0 to 9 which denotes various output voltage/current
settings within the specified ranges of each output for a particular unit or blank for standard output
settings. (may define non-safety related parameters/feature, e.g. reduced primary current limit,
reduced OVP)
*At 440Hz, leakage current is > 3.5mA and therefore must be assessed in the end use application.
