PC Board Mountable Power Supplies
DESCRIPTION
CALEX produces the highest quality, most dependable power
supplies in the industry. These rugged units are reliable, cost
effective power sources for use with a wide variety of
operational amplifiers, function modules, and data conversion
circuits. All units employ industry standard pin configurations
for system upgrading by replacement of or substitution for
supplies from other manufacturers.
All CALEX power supplies feature a 5 Year Warranty and are
characterized by tight regulation, low noise, and outstanding
stability. The short circuit protection features “foldback”
current limiting, so all units can be shorted indefinitely without
damage.

Specifications subject to change without notice.
Single 5 Volt output models have output overvoltage protection
which operates between 5.8V and 6.85 Volts. Power must be
removed to reset the clamp.
Power Supply Mounting Kit Options
Two types of mounting kits are available for convenient
installation of CALEX power supplies. The MK215-022 consists
of a PC card with a 22-pin connector for use in racks. The
alternative, our MK215-08BDV, employs a barrier strip type
connector for chassis mount applications. Two screws hold
the power supply firmly in place on the PC card without need
of soldering.
