J & JJ modules can be used in slots 1-5 at 30-41V at 10A max, For output of 48V at 8A max. For voltages between 41 and
•
48V the current is linearly interpolated.
K & KK modules can be used in slots 1-5 up to 15A.
•
M & MM modules can be used in slots 1-5 up to 8A/channel.
•
L & LL modules can be used in slots 1-4 up to 25A/ channel and in slot 5 up to 20A per channel.
•
N & NN modules can be used in slots 1-5 up to 5A/channel for output voltages up to 29V, For output voltages 29.01V to 32V
•
maximum rated current is 1A.
P & PL modules 18-29V outputs can be used in slots 1-3 up to 5A and in slots 4-5 at up to 4A. P & PL modules 5-16V
•
outputs can be used in slots 1-3 up to 8A an in slots 3-4 at up to 6A.
Q & QQ modules can be used in slots 1-5 up to 25A/channel.
•
R & RR modules can be used in slots 1-5 up to 60A/ channel.
•
S & SS modules can be used in slots 1/2 up to 75A, Slots 2/3 up to 71A, Slots 3/4 up to 69A & Slots 4/5 up to 66A.
•
T & TT modules can be used in slots 1-5 up to 60A
•
U & UU modules can be used in slots 1-3 up to 16A, slot 4 up to 15A and slot 5 up to 13A
•
W & WW modules can be used in slots 1-5 up to 15A/channel
•
Z & ZZ modules can be used in slots 1-4 up to 25A/channel and in slot 5 up to 20A per channel.

The following limitations also apply:
(a) For power supplies having one or more A, AA, AL, R, RR, T and / or TT modules and mounted vertically with the airflow
downwards, the output is limited to 350W.
(b) For power supplies having one or more F or FF modules, the output is limited to 375W, only when operated in a vertical
position with the fan on top of the power supply.
(c) For power supplies fitted with an LSF option fan, the output is limited to 300W and 60AT. Operation in a vertical orientation
with the fan at the top is not permitted.
(d) For power supplies fitted with the fan reversed (RA option), the output is limited to 300W and 60AT. Operation in a vertical
orientation is not permitted.
(e) For power supplies having input or output connector housings fitted the total output is limited as follows:
PSU Orientation
Vertical with fan at top
All other orientations
subject to a maximum total power output of 400W and a minimum mains input voltage of 90Vac.
Where P = maximum total output power and Vin = mains input voltage
An example of a product would be: CA400 @B @B @C @/@E @M where @ and @/@ would be written on the product label as
numbers representing the voltage of the module e.g. 5B.
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.
Input Connections:
Input tabs - 6.3mm x 0.8mm, tin plated brass, rated 15A.

Output Connector Ratings:
1. 6.35mm fastons are rated at 15A.
2. 9.5mm Faston terminals are rated at 32A (Tab thickness = 1.0mm, suitable Faston terminals are AMP
151667-2 or AMP 280223-2
3. M5 screw terminals are rated at 100A subject to the wire and wire connector used to connect them.
Maximum recommended torque setting for M5 screws is 2.5 - 3.0Nm.
