UF-2000A / UF-4000A / UF-R4000A Fuente de poder (anteriormente conocido como UNIFLOW 4, UNIFLOW 4R)
UF-2000A / UF-4000A / UF-R4000A es una nueva fuente de poder para las tecnologías de soldadura por reflujo con barra caliente, sellado térmico, laminado ACF y encastrado térmico. Utiliza la tecnología de calor pulsado para suministrar calentamiento con un objetivo específico y control preciso de la temperatura para distintos componentes, incluidos los circuitos flexibles, cables de cinta, alambres, componentes de montaje superficial, conectores de extremo de uno o dos lados y unión por termocompresión de cintas de oro.
Key Features UF-2000A / UF-4000A / UF-R4000A Power Supply
- Closed-loop temperature and time control
- Stores 63 heating profiles
- Remote programming via RS-232/485
- Two thermocouples for process control and auxiliary monitoring
- Comprehensive and informative user interface: (Graphic and numeric process data, Status and alarm messages, Heat profile setting and envelope limits, Temperature error indicators, User scalable time axis, Real time temperature plot)
- Choice of a standard unit with built-in transformer or remote unit with small control unit and remote transformer. There are four versions of the remote transformers with a choice of two energy levels and two thermode voltage ranges for additional application flexibility
