Calex Manufacturing Co. Inc.
Powering the Next Generation of Mobility
Calex offers a variety of cutting-edge DC-DC power converters and AC-DC battery chargers for e-mobility and industrial applications. Calex's power conversion products offer the highest efficiencies and power densities in ultra-compact, light-weight packages, all of which are designed, qualified, tested and manufactured in our Concord, CA facility.
Calex Manufacturing Company, Inc. announces the launch of the BCA (48S12.3K0BCA), a 3kW Bi-Directional non-isolated DC/DC converter. The BCA is compact and light-weight, weighing only 2.86 pounds, and features a low-profile design with dimensions measuring 8.67 x 6.14 x 1.01”. The ruggedized design boasts an efficiency of 97%, one of the highest power densities in the industry. The packaging and thermal design makes the converter ideal for harsh shock and vibration requirements, as well as easy integration with a battery pack. Standard Hybrid Electric Vehicle architecture typically requires the use of two independent batteries at different voltages, and Calex created the 3kW Bi-directional DC/DC converter in response to these requirements. The BCA charges a low side (12V) battery during normal operation (buck mode) and charges or assists the high voltage (48V) battery in emergency situations (boost mode). In the event that the 48V battery requires charging while in the boost mode, the unit enters into pre-charge mode. The BCA’s features include a disconnect switch based on a back to-back MOSFET configuration for the low side (12V battery), reverse voltage protection, short circuit protection, as well as low standby current for the low side. The baseplate of the enclosure allows for ease of mounting to a chill plate or chassis. The operational baseplate temperature range of the BCA is -40?C to 100?C. The BCA uses a Controller Area Network (CAN) 2.0B interface for complete control of the converter, as well as monitoring the LS current and the internal temperature. Additionally, the BCA uses a high speed CAN-Transceiver for communication with the microcontroller. “The BCA provides a complete solution for in-vehicle power distribution in 48V/12V battery configurations, making this an outstanding choice for OEM vehicle electrical systems,” says Michael McNally, director of product marketing at Calex Manufacturing.

Calex Manufacturing Company, Inc. announces the release of the 24S53.19FXW DC-DC converter. Ideal for battery connect applications, the converter meets the most stringent performance standards for transportation, industrial, and process control applications. This model represents the final product in Calex’s FXW series of DC-DC converters, exhibiting unparalleled power density of 181W/in³ over a 9-36 VDC input range in a ruggedized full brick package that delivers 1000-Watts of output power. The 24S53.19FXW boasts high efficiency and power density by incorporating advanced digitally controlled synchronous rectification technology and case construction that optimizes thermal performance. With a footprint of 2.5 x 4.7 x 0.52 inches, the converter operates at a fixed frequency of 200 kHz and a temperature range of -40 ⁰C to +105 ⁰C. Additionally, the converter can deliver full output power without derating up to 90 ⁰C. Heatsink options are available for extended temperature use. All models in the 1000-Watt FXW series feature a 4:1 input voltage range; output voltages of 12, 24, 28, 48 and 53 VDC; remote ON/OFF; remote sense and TRIM that allows users to adjust the output voltage +10% to -40%. Mindful of battery powered applications, an ON/OFF function is available to minimize the current draw from the batteries when the converter is in the off state. All FXW models are protected by over current, short circuit and over temperature protection. The FXW series is UL60950 approved.
