DC/DC Converters
These printed circuit board mounted products are used in telecommunications, medical instruments, military and industrial control systems. Input voltages range from 3VDC to 300VDC. Output voltages range from 0.75VDC to 180VDC. Isolated and non-isolated products are available in both surface mount and through hole configurations. Calex also offers DIN Rail mount converters for process control applications. Calex offers both standard and custom solutions.

CBAM™
Commercial Off-The-Shelf (COTS) power solutions for military and aerospace applications. The CBAM™ offering includes filtering, hold-up, power quality and load sharing modules. All modules are compatible with Calex DC/DC converter products.

Power Supplies
Encapsulated printed circuit board mounted AC to DC power supplies with power levels from 1.5 watts to 10 watts. These are low noise linear designs and are typically used in analytical instruments, medical instruments, industrial scales and weighing systems.

Voltage Multipliers
Custom encapsulated high voltage multipliers for a variety of applications including X-Ray systems and mass spectrometers. Output voltages run as high as 15kVDC with inputs up to 5kVAC peak to peak. The multipliers provide DC output power up to 25 watts. Additional power and/or voltage requirements will be reviewed by the Calex custom engineering team.

Manufacturing Operations
Calex has manufacturing operations located in two plants totaling approximately 40,000 square feet. One plant is located in Concord, California and is used to introduce new products and support low volume/high mix production.
The other plant located in Tijuana, Mexico is dedicated to high volume products. Both plants utilize the same production equipment and all products can be built at either facility.

8 - SMT Work Centers
3 - Solder Paste Screen Systems
3 - Reflow Ovens
4 - Wave Solder Systems
8 - Burn In Racks
8 - Automatic Test Systems

Both plants are connected with a single ERP system integrated through a Wide Area Network (WAN) to optimize inventory and reduce lead-times. Calex supports it's customers with minimized lead-times and flexible delivery schedules to support Just in Time (JIT) planning and inventory control.
