February 08, 2017 by Jeff Shepard

Technology Dynamics Inc. announced the ruggedized TWM Series of bulkhead power supplies intended for various industrial and military applications. The power supplies operate with a variety of inputs including 100- to 260-Vac 50/60 Hz and 400Hz to dc of 12V, 24V, 48V and 120V. The TWM series can be optionally-equipped with a supercapacitor output bank to enable the unit to supply up to 300A load pulses, and absorb back energy from motors and inductive loads which are started and stopped abruptly.

The series is designed for use in military shipboard applications, ground command and control rooms, as well as utility control rooms. These supplies are designed to meet MIL-STD-461 for EMI and MIL-STD-810 for environmental immunity. The units can be optionally-equipped with communication capability to monitor and control output voltage and current.

The TWM1000-XXX model is rated for 1000W output, while the TWM2000-XXX is rated for 2000W. These supplies can be used to replace or charge batteries. They can be operated in parallel or customized to enable a single unit to deliver up to 3kW.

Standard interface is by military circular connectors but customized versions with bus bars for output and terminal blocks for input are offered. The TWM series mounting is done using the side mounted L-brackets. The 1000W version measures approximately 13” x 12” x 4” and it weighs 7.5 kg.
