Alpha 800 Instruction Manual
•
F modules can be used up to 20A in slots 6 and 7 and up to 33A in all other slots.
•
G modules can be used up to 15A in slots 6 and 7 and up to 25A in all other slots.
•
H modules can be used up to 3A in slot 7 and up to 5A in all other slots. For 29.01 - 32V output current is limited to 1A max
for all slots.
•
J modules can be used up to 6A in slots 6 and 7 (for 30-48V). For all other slots the max. permitted current is
limited to 8A at 48V and 10A at 41V. For intermediate voltages interpolation is used to determine the max.
permitted current. For outputs in the range 36-41V max. current is 10A.
•
J module Ampere Turns is calculated by AT = (Iout + 15)*4
•
K modules can be used up to 10A in slot 6/7 and up to 15A in all other slots.
•
L modules can be used up to 15A in slot 7 and used up to 25A in all other slots.
•
M modules can be used up to 5A in slot 7 and up to 8A in all other slots.
•
(a) N modules can be used up to 5A for outputs up to 29V. For 29-32V output current is limited to 1A max.
•
(b) N modules can be used up to 3A in slot 7 and up to 5A in all other slots.
•
P modules can be used up to 5A on the 18-29V channel in slots 1 to 6 and up to 3A in slot 7.
•
P modules can be used up to 8A in the 5-16V channel in slots 1 to 6 and up to 5A in slot 7.
•
Q modules can be used up to 25A in slots 1-6. In slot 7, this is 15A.
•
R modules can be used up to 60A in any slot.
•
S modules can be used up to 75A in slots 1/2, 76A in slots 2/3; 51A in slots 6/7 and up to 85A in all other slots. When the
psu is operated in a horizontal orientation (with the ratings label uppermost) the S modules may be used up to 85A in slots 2/3.
•
T modules can be used up to 37A in slot 6 and 7 and used up to 60A in all other slots.
•
U modules can be used up to 16A in all slots.
•
W modules can be used up to 15A in all slots.
•
Z modules can be used up to 15A in slot 7 and used up to 25A in all other slots.
Additional module limitations:
When using remote sense, the max output voltage will be reduced by 0.5V for L, S, T, Q and R modules, and
by 1.0V for C, D, F, G, J, M, K, N, U Modules.
Ampere turns for J module is calculated as AT=(output current + 15A) x 4.
Adjusting output voltage beyond the stated range may cause overvoltage protection (OVP) to operate, whereby all
outputs will turn off. To reset OVP, turn back output voltage adjustment and remove the mains supply for 30
seconds.
SELV and Outputs Connected In Series:
Outputs are SELV except as described below:
Non-earthed outputs that have secondaries with 2 or more turns are non-SELV as a single fault in the secondary

may make them exceed the SELV limit between output and earth.
Non-earthed outputs that are connected in series are non-SELV unless all the seriesed outputs use 1 turn

secondaries and there are no more than 3 outputs connected in series.
Outputs connected in series are non-SELV if the total output voltage + 20% of the max. rated output voltage of

the output with the highest rated voltage exceeds 60Vdc (the 20% addition allows for a single fault in any one
individual channel).
The total voltage of a seriesed output must not exceed 160Vdc.

If any output or seriesed output is non-SELV then all the outputs in the PSU must be considered non-SELV.

Non-SELV outputs must be guarded or a deflector fitted during installation to avoid a service engineer making

inadvertent contact with the output terminals, or dropping a tool onto them.
All outputs have operational spacings to earth, and due consideration must be given to this in the end product

design.
Energy Source Levels and Outputs Connected In Series:
Outputs are ES1 except as described below:
Non-earthed outputs that have secondaries with 3 or more turns are ES2 as a single fault in the secondary may

make them exceed the ES1limit between output and earth.
Non-earthed outputs that are connected in series are ES2 or ES3 unless all the seriesed outputs use 1 turn

secondaries and there are no more than 3 outputs connected in series.
Outputs connected in series are ES2 if the total output voltage + 20% of the max. rated output voltage of the

output with the highest rated voltage exceeds 60Vdc (the 20% addition allows for a single fault in any one
individual channel) or ES3 if the total output voltage + 20% of the max. rated output voltage of the output with the
highest rated voltage exceeds 120Vdc
