Non-Encapsulated 1500-Watt 1U COTS DC-DC Converters
Technology Dynamics Inc. announces the release of their new COTS TDDC series of 1U dc-dc converter modules. This robust and ruggedized construction allows high performance and superb reliability. With reduced size and weight along with higher efficiency (SWaP), it provides a high-density, space saving solution for applications across several industries including military (COTS, MOTS, Custom), telecom/datacom, utility, oil & gas, automation, and alternative energy among others. The TDDC series delivers up to 1500W of power and offers dc input voltage range of 18- to 32-Vdc. The output (24V or 48V) is adjustable and tightly regulated to ±1% (load) and ±0.5% (line).
Features include parallel/redundant operation, inhibit, Power-OK alarms, system reset signaling, active current sharing and programming/monitoring functions. In addition, the converters are fan cooled with a standard operating temperature range of –20 to +75 degrees C (derate 2.5%/degree C from +55 degrees C), with an option for -40 to +75 degrees C.
The unit includes forced current sharing, heavy duty output termination, remote inhibit, OV, OL, OT protection and it is designed to meet MIL-STD-810 and 461 standards. Forced current share makes this IU dc-dc converter suited for parallel connection.
Custom output voltages are available upon request with mechanical and electrical modification readily done. For MIL-STD-461F compliance an external EMI filter is needed. Additional available options include conformal coating, remote voltage adjust, rack mount/panel mount and parallel/redundant operation. The converter may be housed in an industry-standard 1U 19†racks. Other custom mounting configurations are also available.
