Induction furnaces have gained popularity with laboratories as they offer a clean, controllable melting process that is quicker than conventional melting furnaces and uses less energy. The heat used to melt substances is generated within the furnace using magnetic fields rather than an external heat source, which can lead to contamination.
A new furnace design required programmable power supplies capable of providing 0 to 30V with power levels of 10kW and 15kW. The development team contacted TDK-Lambda’s sales team, who suggested two models from the GENESYS+™ series.
The first was the 2U high GSP30-340-3P400, which can deliver 10200W, with currents up to 340A and the second, the 15300W rated 3U GSP30-510-3P400 model with current levels up to 510A. Both models accept a three-phase input of 342 to 460Vac. A parallel rack kit was also purchased to put two power supplies in parallel for additional power.
All the models in the five-year warranty GENESYS+™ series share common programming functions, with built-in LAN, USB, remote isolated analogue and RS-232/RS-485 interfaces for remote operation. Waveforms can be created and stored for later use in the internal memory.
