CHOPPER (DC-DC CONVERTER) TRAINING KIT
MODEL: CTK-200
The CTK-200 is a versatile, robust and easy to use training kits used for teaching,
learning and constructing circuits based on chopper (DC-DC converter)circuits theory
and fundamentals. Covers both step down(Buck) and step up(Boost) converter
circuits. Suitable for basic power electronics circuit designs and application.
The CTK-200 is a self-contained system, equipped with the power supply modules,
various experiment plug in modules, user guide, experiment manual, connection
cables and related accessories.
For each experiment, circuits are constructed by the user using safety connection
cables and built-in connector sockets to avoid any hazardous risk to the user and also
the training kit itself. Each experiment is detailed in the lab workbook.
Each of these modules can be directly placed on the laboratory lab bench or can be
mounted onto an optional robust table top frame rack (ITEM: TFR-003) when
conducting experiments. Connection using 4mm safety sockets.
