Description
The unique CALEX “CM” design creates the most flexible and
well-engineered power supply package on the market today.
These chassis mountable supplies are ideal for use with
dedicated microprocessor systems, instrument design and
test equipment. The CM units can also be used as
supplemental bench or laboratory power supplies.
The special “clamp” type barrier strip secures the wire without
twisting. Note the protected, recessed, barrier strip facing the
top of the case. This allows all connections to be made in tight
quarters while protecting the barrier strip from physical
damage.
Nothing else offers this combination of ruggedness, flexibility
and convenience. All CALEX chassis mount power supplies
are guaranteed to provide at least 5 years of reliable service.
Models CM1.5.500 and CM1.5.1000 have output voltage
protection which operates between 5.8 and 6.85 Volts. Power
must be removed to reset the overvoltage clamp.

Mounting Adapter
Model MP 90
The model MP 90 interface plate is an adaptor between the
mounting pattern of CALEX CM power supplies and that of
some competitive products. This allows you to replace worn-
out and obsolete models with reliable CALEX modules.
The interface plate is made of anodized aluminum with
threaded holes and through holes for your choice of quick and
convenient mounting.
