Input voltages between 85 and 90V are permitted providing the total output power is derated to 94% of the values
given below.
* 47 - 63HZ for all 60601-1 standards.
Output modules:
• Channel 1 output provides hazardous energy and must not be made user accessible. It 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.
• Adjusting output voltage beyond the stated range may cause overvoltage protection (OVP) to operate, whereby the
output will turn off. To reset OVP, turn back output voltage adjustment and remove the mains supply for 30 seconds
and then switch back on.
SELV and Outputs Connected In Series:
All outputs are SELV.
Modules connected in series or parrallel
Module outputs cannot be paralleled to other outputs in the same power supply or paralleled to other modules in
another unit. Paralleling of modules for redundant operation i.e. Output load does not exceed the load current of a
