1 for 175 or 1D (1D for Double Insulated Class II unit) y = Blank for Y2 capacitors from output to earth (except 1D models), P for Y1 capacitors
from output to earth (except 1D models); a = Number of Outputs : 1; b = Channel 1 Output Voltage where: T is for 12V, F is for 15V and G is for
24V; c,d,e = O (for omit) - non-safety related options; f = Standby supply: 12Vdc (S,S1,S2,S3,S4 versions) 5Vdc (S5, S6); g = U for U chassis,
C for U chassis with cover, K for custom chassis with cover and IEC inlet or blank for Open Frame; h = Blank is the standard upright output
connector, R is for the right angle output connector, S is for the screw terminal; i = Blank for standard leakage, L for low leakage; jkl = Three
numbers from 0 to 9 which denotes various output voltages and currents within the specified range of channel 1 output for a particular unit or
blank for standard output setting.
H - may be replaced with a sequence of five alphanumeric references as follows: 1,2,3 or 4; followed by 5,T,7, F or G; followed by 1,2,3,4,5 or 0;
followed by 3L, 5L, TL, FL, T, F or G followed by Y or 0; followed by 3H, 5H, T, F, TH, FH or 0H followed by P or 0
I - may be replaced with N, N1, N2, N3, N4, N5 or blank
J - may be replaced with U, C, F, I or blank
K - may be replaced with R, H, HR or blank
L - may be replaced with any numeric number between 000 and 999 denoting customer specific configurations (non safety critical)
N - may be replaced with a sequence of five alphanumeric references as follows: 1,2,3 or 4; followed by 5; followed by 3, 3H or 0; followed by
3L, 5L, TL, FL, T, F or G followed by Y or 0; followed by T, F, TH, FH or 0H followed by P or 0
P - may be followed by N3, N4, N5 or blank

S - To be replaced with a sequence of four alphanumerics of the following combinations: @B, @C, @CM, @BH, @/#DB, @/#DA (where @ is the
output voltage on single output module and the channel 1 voltage on dual channel modules; and # is the channel 2 voltage on dual channel
modules), or B/S where a blanking plate is fitted in place of a module. Where modules are combined in series: @BB or @BHB or @BBH or @BHBH
or @CC or @CCM (where @ is the total voltage of any two B, BH, C or CM modules connected in series), @/#BDB or @BHDB (where @ is the
total series voltage of any B or BH module and DB module channel 1 and # is the output voltage of DB module channel 2), or @HDB (where @ is
the total series voltage of any DB module channel 1 and channel 2)
V - Where V = 3 thru 48
W - Where W = 3 thru 24
XXX - Maybe CSM, K or M
