EFE400M Instruction Manual
Unit Nomenclature
EFE400M or EFE-400M models as described below:
Units may be marked with a Product Code: U6x or Y6x where x may be any number of characters.
Unit Configuration (Description :) Code may be prefixed by NS # followed by / or - (where # may be any number of
characters indicating non- safety related model differences).
Unit Configuration Code:
EFE400Mxy-a-b-cdef-gh-i-j-klm
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
D for Class II (with Y1 capacitors)
a = Channel 1 output Voltage (see Ch1 in the table below, adjustment range column).
b = Standby voltage: see standby voltage in table below.
c = BC for cover and U chassis without fan grill, with fan fitted (temperature controlled). (Y60001x
model only)
HN for Open frame, no fan, with 12V / 1A fan supply.
HU for U chassis (not EFE400MxD models), no fan, with 12V / 1A fan supply.
HC for Cover + chassis (not EFE400MxD models), no fan, with 12V / 1A fan supply.
EC for Cover + chassis (not EFE400MxD models), end fan (temp controlled).
NN for Open frame, no fan, no fan supply.
NU for U chassis (not EFE400MxD models), no fan, no fan supply.
NC for Cover + chassis (not EFE400MxD models), no fan, no fan supply.
HP for perforated cover, no fan, with 12V / 1A fan supply.
NP for perforated cover, no fan, no fan supply.
TF for Cover + chassis (not EFE400MxD models), top fan (fixed speed)
d = M for Molex KK type 41791 input connector or equivalent.
S for Molex Sabre type 43160 input connector or equivalent.
e = D for AC input with dual fuse.
F for AC/DC input with dual fuse.
E for single fuse input in the Live line.
G for single fuse input in the + line.
f = L for low Leakage.
R for reduced Leakage.
T for tiny Leakage. *
Z for EFE400MxD models (Class II).
g = Y for Oring FET included.
N for no Oring FET.
h = T for inhibit.
E for enable.
N for no remote signals
i = V for vertical output connector or nothing for horizontal output connector.
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, 18PD = 1.8V of positive load regulation).
klm = 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)
* L < 300uA leakage, R < 150uA leakage and T < 75uA leakage.
