•
(a) C modules can be used up to 16A for outputs up to 12V. For 15-16V outputs C modules can be used at up
to 12A.
Maximum module output current derates linearly between 12V and 15V.
•
(b) C modules can be used up to 10A in slot 7 and up to 16A in all other slots, subject to the limitations of (a).
D modules can be used at up to 8A in slots 1-6. In slot 7 this reduces to 5A.
•
E modules can be used up to 5A in slot 7 and up to 8A in all other slots.
•
EQ and EB modules can be used up to 5.6A in slot 7 and up to 9A in all other slots.
•
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.
•
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 c 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.
