AC/AC power supply: integral cycle thermal load converter
3x400 VAC, 15-75 A, 10-50 KVA
Cognito Quam Electrotechnologies Ltd
They interface with most (if not all) hardware as well as most automation equipment in the market and are an effective thermal load interface in many applications. They are all fully protected, digitally-controlled and programmable units. They are simple to install and are effectively employed in applications driving:
* All types of resistive and inductive heaters,
* Ovens, and
* Boilers.
Main features of the line include:
* Low noise integral cycle thyristor control. Only complete cycles are conducted to the load, thus eliminating all di/dt and dV/dt caused interference,
* 3phase, 15 - 75 A (per phase), 230/400 V (nominal; 1600 VDC power circuit),
* Drives both, Wye/Star and Mesh/Delta connected loads,
* Complete, electronic protection (overcurrent, undercurrent, overvoltage, undervoltage, against noise, faults and disturbances in the supply, phase integrity, internal temperature),
* Versatile two input user/control interface,
* Galvanically isolated bit outputs ("Idle", "Run", "Load Fault", "Fault"),
* Small power supply 20 VDC available to power a local sensor or other automation device,
* Installation-friendly, robust, space-saving "bookcase" style enclosure.
